Abstract

The production of fuels, such as gasoline, diesel, and jet fuel, the use of sales gas through GTL-FT (Gas to Liquid Fischer Tropsch) has received increasing attention over the last few years. In this research, the Gas to Liquid process to produce jet fuel from Sales Gas is simulated. Kinetic data and simulation basis was taken from published journal papers. Simulation was initially validated based on reference and optimized based on several aspects: ATR and FT operating temperature, hydrocarbon-steam-ratio, and staging ratio while looking into several objective parameters: the H2/CO ratio in syngas produce, reactor conversion, and jet fuel (C6-C16) product mol fraction. An increase in the steam-gas ratio and an increase in operating temperature on the ATR will result in an increase in the resulting H2/CO syngas ratio. The staging effect on ATR will also increase the value of the H2/CO ratio of the resulting syngas. The increase in operating temperature on the Fischer Tropsch will reduce the liquid fuel gain and mole fraction yield to be obtained. Furthermore, staging on the reactor fischer tropsch will increase the actual conversion and mole fraction yield of jet fuel
