Abstract

A novel concept of cracking-based oligomerization of naphtha (C5-C8) to produce higher range hydrocarbons (C9-C15) suitable for the jet fuel applications has been explored by using various zeolite type catalysts. Among the bi-metallic BEA, MOR, Y, ZSM-5 and Nano ZSM-5 based catalysts, the bi-functional Pt-Sn/Nano ZSM-5 catalyst exhibited promising catalytic activity to give higher range hydrocarbons in a single step vapor phase reaction. The catalyst produced 47 wt.% higher range hydrocarbons (C9-C15) from naphtha (C5-C8) at 400 ºC and 15 bar pressure, which is first of its kind to observe on any solid acid catalyst to the best of our knowledge. Further, the studies are also conducted on various other zeolites metal functionalized by similar manner so as to understand the effect of zeolite type and the metals.
