Catalytic Pyrolysis of Waste Bicycle Tires and Engine Oil to Produce Limonene

NaOH, dolomite and NiCl2 were used as catalysts to examine their effects on co–pyrolysis with waste bicycle tires (WT) engine oil (WEO). The pyrolysis behaviors investigated by thermogravimetric analysis. activation energy of the catalytic main reaction stage was derived Kissinger–Akahira–Sunose (KAS) method under four different heating rates conditions. calculations show that all three can reduce reaction. Co–pyrolysis WT WEO performed in a self–made lab bench at 600 °C explore impact distribution three–phase products. properties gas products characterized FTIR Py–GC/MS (Agilent 7890B, Santa Clara, CA, USA). With mixing catalysts, (Eα) decreased 15–30% process. NaOH increased yield 7% 10%. significantly improve CH4. proportion limonene 19.65% 10% NaOH. This article provides new for efficiently producing
