摘　　要：选择正己烷作为积炭反应物 ,应用WCT - 2型微机差热天平 ,考察了几种由偏钛酸制成的催化剂载体的积炭情况。实验结果表明 :用不同厂家的偏钛酸原料、不同的焙烧温度所制得的催化剂载体 ,其失重量不同 ;用偏钛酸制成的PTA催化剂载体 ,其高温下的抗积炭性能优于椰壳炭载体 ,且水合铝的添加量有一合适的限度 ;其高温下不同时间段的抗积炭性能仍然呈现出偏钛酸制成的PTA催化剂载体优于椰壳炭载体 ,且焙烧温度为 4 5 0℃、水合铝的添加量为 30Selecting normal hexane as reactant of carbon deposit, carbon deposit of several catalyst carriers, which are made from metatitanic acid, has been investigated by WCT-2 computer differential thermal analysis. The results show that catalyst carriers from different metatitanic acid raw materials and different calcination temperatures, the weight losses are different.Anti-carbon deposit performance of PTA catalyst carrier from metatitanic acid under high temperature and in different periods are better than that of coconut carbon carrier, optimum conditions are calcinations temperature 450℃ and hydrate aluminum content 30%.
