文摘
The kinetic behavior has been studied for cracking a commercial feedstock on a hybrid catalyst(with 5 wt % of HZSM-5 zeolite) made up of 80 wt % of a catalyst equilibrated in a fluid catalyticcracking (FCC) unit and of 20 wt % of a catalyst prepared based on a HZSM-5 zeolite. Alaboratory-scale reactor which allows for operation under conditions similar to those ofcommercial FCC units has been used. From the analysis of the gases and gasoline obtained inthe 500-550 
C range, with contact times between 2 and 10 s and for a catalyst/feedstock = 6,the influence of HZSM-5 zeolite presence in the catalyst on gas and gasoline composition andon gasoline research octane number has been analyzed.
