摘　　要：利用提升管中试实验装置,研究了催化汽油二次裂化制丙烯过程中热裂化、氢转移反应的特点和影响因素,给出了不同反应条件对丙烯选择性的影响,考察了丙烯选择性最大点处热裂化反应、氢转移反应的变化。研究结果表明,采用适当的反应温度和剂油比以及缩短反应时间能有效抑制热裂化反应和氢转移反应的发生,提高丙烯的选择性。Thermal cracking and hydrogen transfer reactions Occurred in FCC naphtha cracking for propylene were studied on pilot riser FCC unit. Influence of operation parameters （reaction temperature, catalyst to oil ratio, resident time） on propylene selectivity, thermal reaction and hydrogen transfer reactions were investigated and thermal cracking reaction and hydrogen transfer reactions were discussed at maximal value of propylene selectivity. The result showed proper reaction temperature, catalyst to oil ratio and short reaction time may detriment thermal cracking reaction, hydrogen transfer reactions , and get high propylene selectivity.
