The catalytic cracking of NNJ 150 over USHY, HZSM 5 and SAPO 34 catalysts presented as that the selectivity of light olefins over USHY was the lightest among the three calalysts with a quicker deactivation, while HZSM 5 showed a longer catalyst life and lower selectivity of light olefins, for SAPO 34, both the conversion and the selectivity of light olefins were the lowest.

实现吸热型碳氢燃料这种功能的关键之一是选择适当的化学反应。由于碳氢燃料的裂化是吸热反应，而催化裂化与热裂化相比，能降低反应的温度，因此催化裂化是实现吸热型碳氢燃料功能较好的途径之一。由热力学可知，燃料裂化生成乙烯、丙
