Abstract

Abstract: Ir-ReOx/SiO2 combined with HZSM-5 was used as catalyst for biogasoline production in the biphasic system. The effects of various parameters such as reaction time, temperature and hydrogen pressure on the yield of biogasoline were investigated. The experiment results show that, when using biomass as substrate, a maximum C5/C6 alkane yield is obtained under the optimal conditions with the reaction temperature being 170 ℃ and hydrogen pressure 7 MPa. In addition, It is found that dehydration reaction is the control step in the experiment. Compared with other catalysts, HZSM-5 has suitable Lewis acid and Bronsted acid, and it has a channel architecture which can increase substrate concentration and thus shows better catalytic activity.

Key words: biphasic system；C5/C6 alkane, dehydration, solid catalyst, biomass
