Article Citation - WoS: 12Citation - Scopus: 15Evaluation, characterization, and engine performance of complementary fuel blends of butanol–biodiesel–diesel from Aleurites moluccanus as potential alternative fuels for CI engines(SAGE Publications Inc., 2018) Atabani A.E.; Mekaoussi M.; Uguz G.; Arpa O.; Ayanoglu A.; Shobana S.Biodiesel has gained worldwide attention due to its renewable aspects. However, it needs more quality improvement. Recently, butanol has been considered as a favorable alternative fuel or additive over methanol and ethanol in compression ignition (CI) engines. In this regard, the present work deals with the evaluation of butanol–diesel–biodiesel blends as potential alternative fuels. In this work, biodiesel has been produced from Aleurites moluccanus oil followed by blending with Euro-diesel and butanol. Important characteristics such as kinematic viscosity, density and cloud point besides FT-IR, UV-vis spectra, TGA, DSC and NMR (13C and 1H) were analyzed. Some important engine and emission performance parameters, such as BP, BSFC, CO, HC, NOx and EGT were also studied in this work. Results revealed that blending butanol and Euro-diesel with biodiesel improves the properties of pure biodiesel such as kinematic viscosity (2.41–3.55 mm2/s) and density (841.8–884.6 kg/m3), while maintaining an acceptable range for cold flow properties that are analogous to Euro-diesel. In addition, reduction in BP (24.65–26.35%), HC (52.57–38.71%), and CO (39.18–30.4%) was observed for all the blends at full load compared to Euro-diesel. However, increases in both BSFC (38.17–41.14%) and NOx (24.18–8.35%) were observed. Overall, the blends appear to be good alternatives to biodiesel–diesel blends. Thus, butanol–biodiesel–diesel blends can be considered as potential sustainable fuels for fossil diesel. © The Author(s) 2018.Article Photovoltaic Solar Power Plant of Soguksu: A Case Study(2025) Saka, Kenan; Ayanoglu, AbdulkadirInvestments in photovoltaic solar power plants continue to increase across all provinces of Türkiye. However, Bursa is not among the regions that receive the highest levels of solar radiation compared to the eastern parts of the country. The Soğuksu power plant, located in the village of the same name in Bursa, was commissioned in March 2017 with an installed capacity of 7 MW. In this study, the actual generation data of the power plant for 2022 were analyzed, and the performance ratio (PR) and capacity factor (CF) were calculated. The results show that the minimum electricity generation occurred in December 2021 with 401.21 MWh, while the total electricity production in 2022 reached 10.64 GWh. During the summer season, the plant generated 7,262.8 MWh, corresponding to 68% of its annual production. The lowest performance ratio was observed in June at 75.1%, while the highest capacity factor was recorded in July at 28%. Furthermore, the performance ratios for November, December, and January exceeded 100%. Since the PR is calculated based on the solar energy values reported in the regional solar atlas, such results indicate a notable discrepancy between the published data and the actual site conditions. The exceptionally high PR values during the winter months may suggest that the region experiences milder winters and receives higher solar radiation than the atlas values imply.Article Citation - WoS: 27Citation - Scopus: 27Perspective of safflower (Carthamus tinctorius) as a potential biodiesel feedstock in Turkey: characterization, engine performance and emissions analyses of butanol–biodiesel–diesel blends(Taylor and Francis Ltd., 2017) Al-Samaraae R.R.; Atabani A.E.; Uguz G.; Kumar G.; Arpa O.; Ayanoglu A.; Mohammed M.N.; Farouk H.Safflower (Carthamus tinctorius) is widely farmed in Turkey. This study investigates the physicochemical properties of safflower biodiesel and its blends with Euro diesel and butanol. A polynomial curve-fitting method was used to predict kinematic viscosity and density of the ternary blends. Furthermore, characteristics such as DSC, FT-IR, UV-Vis and TGA were adopted to evaluate the influence of butanol addition on biodiesel–diesel blends. Engine performance parameters such as BP, torque and BSFC and emissions such as CO, HC, NOx and EGT were studied. Safflower methyl ester satisfied both EN 14214 and ASTM D 6751 standards regarding viscosity, flash point and density. However, iodine value was quite high. Oxidation stability fails to satisfy either standard. This is due to the high level of unsaturated fatty acids (91.05%). A reduction in BP, torque, HC and CO coupled with an increase in BSFC, NOx emissions and EGT was observed for all blends compared to Euro diesel. Overall, all blends appear to be good alternatives to biodiesel–diesel blends. This work supports that biodiesel can be blended with diesel and butanol as ternary blends (up to 20%) for use as a fuel in compression ignition (CI) engines. Therefore, combustion characteristics of blends shall be further investigated. © 2017 Informa UK Limited, trading as Taylor & Francis GroupArticle Chemical characterization of waste tire pyrolysis products(International Advanced Researches and Engineering Journal, 2021) Uğuz, Gediz; Ayanoğlu, AbdulkadirThe significance of tire disposal, an attractive waste to convert into burning oil or absorber etc.,has been increasing day by day. However, if it does not change into a useful form, it will damagethe nature and the living things. Thus, pyrolysis, a well-known method, which is used to convertrecycle tire waste into gas, liquid and char. On the other hand, the waste pyrolysis oil or wastetire oil (WTO) has a substantial avaliable calorific value similar to those of fossil fuels. Due topyrolysis reaction, high amount of sulfur is detected in the WTO; therefore, another step ofexplosion applied to WTO to decrease sulfur and also re-upgrade quality of oil with suchcatalysts as Calcium Oxide (CaO) and Natural Zeolite (NZ) at a ratio from 2 to 10 with anincrease of 2 for each step, individually. It is noticed that distillation test is a key analysis forseparation discrimination of rich or lean quality fuel. As a consequence of mixture of catalystWTO reactions, the best curve was observed at a 10% CaO-WTO mixture which was close todiesel#2 and the mixture was separated into two new fuels as light (Gasoline Like Fuel orabbreviated as GLF) and heavy one (Diesel Like Fuel or shortened as DLF) due to temperaturedifferences. According to distillation, FT-IR, NMR and UV–vis were used to analyze WTO,GLF and DLF for defining their characterization as well. Thus, the characterization result data ofsamples have quasi-equivalent with standard petroleum in open literature, and can be combustedin engine as well.Article Elektrikli ve Konvansiyonel Otomobil Klimalarının Donanımsal Karşılaştırılması(2025) Saka, Kenan; Ayanoglu, AbdulkadirSürücüler ve yolcular için konforlu bir yolculuk sağlayan otomobil klima sistemleri uzun süredir otomobillerin vazgeçilmez bir parçası durumuna gelmiştir. Elektrikli otomobil kullanımı ise içten yanmalı motorla çalışan araçlara bir alternatif olarak her geçen gün daha da artmaktadır. Elektrikli araçlarda kullanılan klima sistemi teorikte aynı buhar sıkıştırmalı mekanik soğutma çevrimi olmasına rağmen konvansiyonel taşıt klima sistemlerine göre donanımsal farklılıklara sahiptir. Bu çalışmada içten yanmalı motorla çalışan araçlara ait klima sistemleriyle elektrikli araçlara ait klima sistemlerinin tasarım karşılaştırmasına yer verilmiştir. Çalışmaya her iki tür araç klimalarından beklenilen soğutma görevinin karşılaştırılmasıyla başlanmıştır. Daha sonra bir klima sistemini oluşturan kompresör, evaporatör, kondenser ve kısılma vanası karşılaştırmasıyla devam edilmiştir. Sonuç olarak içten yanmalı otomobillerde bulunan klima sistemi sadece konfor şartlarının iyileştirilmesine katkıda bulunurken elektrikli araçlarda bulunan klima sistemi kabin içi soğutma görevinin yanında batarya ve motor soğutma görevini de yerine getirmektedir. İçten yanmalı otomobillerde ısı pompası uygulamasına gerek yokken elektrikli otomobil klimalarında ısı pompası uygulaması ticari olarak başlamıştır.Article Citation - WoS: 78Citation - Scopus: 92Fuels properties, characterizations and engine and emission performance analyses of ternary waste cooking oil biodiesel-diesel-propanol blends(SUSTAINABLE ENERGY TECHNOLOGIES AND ASSESSMENTS, 2019) Bencheikh, Kamel; Atabani, A. E; Shobana, Sutha; Mohammed, M. N.; Uguz, Gediz; Arpa, Orhan; Kumar, Gopalakrishnan; Ayanoglu, Abdulkadir; Bokhari, AwaisApplication of biodiesel synthesized from waste-based raw materials with numerous solvents (higher chain alcohols) in diesel engines is a topic of great interest. This article examines the effect of biodiesel-diesel-propanol ternary blends. Physio-chemical properties, fatty acids composition (FAC), FT-IR, TGA, DSC, NMR along with some selected engine and emissions performance parameters were examined. Biodiesel was produced from waste cooking oil and exhibits excellent FAC that yields kinematic viscosity, cetane number, oxidation stability, higher heating value and iodine value of 3.93mm(2)/s, 58.88, 7.43 h, 39.45 MJ/kg and 64.92 g/100 g. Propanol blended biodiesel depicted an affirmative improvement in cold flow properties and decremented density. FT-IR and NMR results confirms the existence of biodiesel-diesel-propanol and prove their qualities as reliable methods. DSC and TGA results confirm that propanol reduces the onset and crystallization temperatures of the blends. Engine and emissions performance revealed that propanol addition further increased brake specific energy consumption (BSEC) and brake specific fuel consumption (BSFC) and reduced carbon monoxide (CO), exhaust gas temperature (EGT), nitrogen oxides (NOx) and smoke. This study proves the feasibility of the ternary blends with rewarding benefits in cold flow properties and densities besides acceptable engine and emissions performance results.Article Atık Lastik Piroliz Ürünlerinin GC, ICP-MS, TGA ve DSC Tarafından Karakterizasyon(2021) Ayanoglu, Abdulkadir; Uğuz, GedizBüyük miktarda atık lastik (AL) çevreye atılmakta ve doğa üzerinde tehlikeli etkilere sebep olmaktadır. AL’in geri donuşumu için, piroliz kullanılarak atık lastiklerin gaz, sıvı ve katı ürünlere dönüştürülerek AL’nin zararlı etkilerini bertaraf etmek amacıyla kullanılan etkili bir tekniktir. Bu çalışmada, bir kesikli reaktör kullanılarak iki adımda sıvılaştırma yapılmıştır. İlk olarak, atık lastik gaza, atık lastik yağına (ALY) ve karbon siyahına dönüştürülmüştür. İkinci adımda ise ALY, farklı oranda Kalsiyum Oksit (CaO) veya Doğal Zeolit (NZ) ile karıştırılarak; benzine veya dizel benzeyen yakıt yüksek kaliteli yakıt elde etmek için piroliz edilmiştir. Distilasyon eğrisi, yakıt kalitesini tanımlamak için iyi bir referanstır. % 10CaO-ALY karışımının distilasyon eğrisi dizel yakıta benzerlik gösterdiği tespit edilmiştir. Fakat karışımın dizel yakıttan daha düşük olan 54 oC'de distile edilmiştir. Bu nedenle karışım, ilk-son kaynama noktalarına göre ayrıştırılarak iki fraksiyon elde edilmiştir. 54 oC ile 150 oC arasında, benzin benzeri yakıt (BBY); 150 oC ile 360 oC arasında dizel benzeri yakıt (DBY)) elde edilmiştir. Elde edilen bu iki fraksiyon, geleneksel yakıtlara benzerliklerini değerlendirmek amacıyla GC, ICP-MS, TGA ve DSC teknikleri kullanılarak analiz edilmiştir. Örneklerdeki ağır metaller ve diğer elementler ICP-MS tekniği ile analiz edilmiştir. TGA yakıtlardaki termal ve oksidasyon kararlılığını belirlemek için kullanılan iyi bir tekniktir. DSC ise yakıt örneklerindeki kristallenmeye başladığı noktanın belirlenmesi amacıyla kullanılmıştır. GC analizi ile gazin ısıl değeri tespit edilip, bununla beraber gaz içeriği de tespit edilerek standard yanabilen gazlarla karşılastıtılmıştır. Elde edilen sonuçlar BBY ve DBY ile sıvılaşmayan gaz numune sonuçlarının motorlarda problemsiz kullanılabileceğini göstermiştir.
