Study on influence factors for FCC naphtha catalytic cracking for propylene
FCC汽油二次裂化增产丙烯过程中主要影响因素的研究

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 shor...
