研究了常压下JP-10燃料在HZSM-5/不锈钢筛网复合膜上的催化裂解。研究发现,HZSM-5/不锈钢筛网复合膜对JP-10裂解具有较好的催化活性。400℃、停留时间6.51 s时,高密度碳氢燃料JP-10在空白不锈钢筛网上不发生任何裂解,而在HZSM-5/不锈钢筛网复合膜上的裂解转化率为15.2%;500℃、停留时间5.67 s时,JP-10在空白不锈钢筛网上的裂解转化率为3.1%,而在HZSM-5/不锈钢筛网复合膜上的裂解转化率高达42.1%。JP-10催化裂解的主要产物为C1-C4、苯、环戊二烯和甲苯,苯的含量随停留时间增加而逐渐增加,而环戊二烯的含量则逐渐减少,C1-C4和甲苯的含量随停留时间变化不大。根据产物分布,提出了JP-10在HZSM-5/不锈钢筛网复合膜上催化裂解的可能反应途径。
The catalytic cracking of JP-10 fuel at atmospheric pressure over HZSM-5 / stainless steel mesh composite membranes was investigated. The study found that, HZSM-5 / stainless steel mesh composite membrane JP-10 pyrolysis has better catalytic activity. 400 ℃ and residence time of 6.51 s, pyrolysis rate of high-density hydrocarbon fuel JP-10 on blank stainless steel mesh was 15.2% at 500 ℃, When the residence time was 5.67 s, the pyrolysis conversion rate of JP-10 on blank stainless steel mesh was 3.1%, while the pyrolysis conversion rate on HZSM-5 / stainless steel mesh composite membrane was as high as 42.1%. The main products of JP-10 catalytic cracking are C1-C4, benzene, cyclopentadiene and toluene. The content of benzene gradually increases with the increase of residence time while the content of cyclopentadiene decreases gradually. The content of C1-C4 and toluene Content with little change in stay. According to the product distribution, a possible reaction pathway of JP-10 on catalytic cracking of HZSM-5 / stainless steel mesh composite membrane was proposed.
