摘要
设计了ＴＰＣ方法研究催化剂前驱体的热分解；对ＴＰＣ方法求取催化剂的热分解动力学方程进行了理论推导；采用ＴＰＣ方法试验求得了Ｎｉ－Ｚｎ／Ｃ催化剂的热分解动力学参数。试验表明，ＴＰＣ方法能直观、灵敏、方便地反映催化剂活性组份前驱体的本征热分解。
new technique of temperature programmed calcination (TPC)is designed to investigate the thermaldecomposition of catalyst precursorThe kinetics equation of thermaldecomposition ln(h/A)=lnk0-Ec/RT is first derived from TPC graph,from which the thermaldecomposition kinetics equation of NiZn/C catalyst can be obtainedExperimental results show that this method is more direct,convenient and sensitive for characterizing the thermaldecomposition process of catalyst than the TGDTA method
