Abstract: A high temperature steady heat conduction flow calorimeter was constructed to determine the catalytic cracking heat sink of endothermic hydrocarbon fuels (EHF). The linear relation for the thermal constant was good and it was believed to be in conformity with Tian’s equation. This calorimeter can be used in experiments reliably. The catalytic cracking heat sink of EHF named RL7 and NNJ-150 on zeolite SAPO-34 were measured at 500℃, 600℃ respectively. Contrasting with pyrolytic cracking heat sink at the same conditions, the results show that the heat sink of NNJ-150 can be enhanced due to the existence of zeolite SAPO34. The endothermic working temperature of EHF could be decreased by 100℃.

摘要： 报道了一套高温下测量吸热型碳氢燃料催化裂解热沉的稳态热导型流动热量计,仪器常数标定结果线性关系良好,符合Tian’s方程,可以正常工作;测定了500℃和600℃下吸热型碳氢燃料RL7及NNJ 150在SAPO 34分子筛催化剂上的催化裂解热沉,并与相同条件下热裂解热沉相比较,结果表明,吸热型碳氢燃料在SAPO 34分子筛催化剂上发生催化裂解能够比热裂解获得更高的热沉,燃料吸热工作温度可降低100℃。
