Aromatization of natural gas liquid using fluoride doped platinum catalyst

Abstract

This research studied the aromatization of Natural Gas Liquid (NGL) by using fluoride doped platinum catalysts. Investigations were performed by varying the temperatures between 350-430℃ under hydrogen pressure of 20-60 psi. Furthermore, the catalyst concentration effects were observed by varying the platinum and fluoride conterts. The effects of solid support were also studied by comparing alumina support with 4A molecular sieve support. Aromatization of NGL occurred well at 430℃ and 40 psi of hydrogen. The appropriate concentraltion of platinum and fluoride were 0.6% and 0.5% by weight respectively. The suitable solid support for aromatization NGL was alumina when compared with 4A molecular sieve. The present process has the advantage of maximizing the yield of aromatics from a mixed feedstock and percent yield of aromatics related to total conversion was 95%.
