Abstract

By using fraction of Yanhua FCC gasoline as a feedstock, the effects of reaction temperature, weight hour space velocity, feedstock performance on yields of liquefied petroleum gas production, and aromatics and propylene are researched in a confined fluidized bed reactor. Aromatization index (AI) and competent parameter (CP) are first proposed to study the mechanistic pathways of aromatization reaction of fraction of Yanhua FCC gasoline. The experimental result shows AI values of FCC gasoline decrease with the increase of the reaction temperature under the same catalyst; CP values and the aromatization reaction function for the same catalyst increase with the increase of the reaction temperature. The isomerization reaction for fraction of Yanhua FCC gasoline has more advantage than that of the aromatization reaction.
