摘要
采用微型固定床反应装置,选用FH-98型催化剂,在催化剂活性稳定阶段且消除内、外扩散影响的情况下,进行废轮胎热解油轻质馏分加氢脱硫反应本征动力学研究,并考察了反应温度（563.15~643.15 K）、反应压力（1.0~3.0 MPa）对加氢脱硫反应的影响规律。结果表明：提高反应温度和反应压力对加氢脱硫反应有利;经F检验及相对误差分析确定建立的动力学模型显著可信,用其描述热解油轻质馏分在FH-98催化剂上的加氢脱硫反应本征动力学是合适的。
Intrinsic kinetics of hydrodesulfurization（HDS） of light fraction of used tire pyrolysis oil over the FH-98 catalyst was studied in a micro-fixed bed reactor during the stage with stable catalyst activity and without internal and external diffusion.The effects of reaction temperature（563.15-643.15 K） and reaction pressure（1.0-3.0 MPa） on HDS were investigated.The results showed that the increase of reaction temperature and pressure was favorable to the HDS reaction.The kinetic model was significantly reliable through F test and relative error analysis.Thus,it was suitable to describe the intrinsic kinetics of HDS of light fraction of used tire pyrolysis oil over the FH-98 catalyst.
