Chemical characterization of waste tire pyrolysis products

Abstract

The 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.
