摘    要:固定床内研究了甲苯裂解特性,考察了熔融盐种类、裂解条件对甲苯裂解率、气体产物及苯产率的影响。结果表明,熔融盐对甲苯裂解有明显的催化作用,添加熔融盐时,相同裂解温度下甲苯裂解率明显提高。在71%Na2CO3+29%K2CO3(NK)盐和8.3%Na2CO3+91.7%NaOH(NN)盐中800℃催化裂解时,与热裂解相比,甲苯裂解率分别提高27%和46%,苯产率明显减少。NN盐催化裂解时,750℃后产物中的氢气主要来源于裂解碳与NN盐的反应。

Abstract:The toluene cracking experiments were carried out in an eutectic salt reactor. Catalytic effects of NN salt (8.3%Na2CO3+91.7%NaOH) and NK salt (71%Na2CO3+29%K2CO3) on the toluene cracking rate, gas product yield and benzene yield were investigated. The results show that the eutectic salts have obvious catalyses on the toluene cracking. When cracking at 800℃ with NK salt and NN salt, the toluene cracking rates are increased by 27% and 46%, respectively, compared with thermal cracking. And the benzene yield is greatly reduced. When cracking with NN salt at a temperature higher than 750℃, H2 in gas product is mainly from the reaction between NN slat and the cracking tar.
