热解和气化过程焦油析出的影响因素分析

Analysis on the influecing factors of the tar extract in the process of pyrolysis and gasification

在热解和气化过程中产生的焦油给气化工业带来极大的不便。讨论了温度、停留时间、压力、气氛、粒径以及床料等对热裂解和催化裂解产生的影响。催化剂的加入对上述因素又产生了新的影响。同时介绍了不同研究者对催化剂性能的研究,在此作出对比。

In the process of gasification, the product of tar is inevitable, which may prove to be a sticky problem to keep for normal system operation. Effects of temperature, residence time, pressure, atmosphere, particle size and bed material, are researched. The accession of catalysts make new effects on all of the factors above. At the same time, the activities of different catalysts are compared by different investigators.
