Abstract

Fischer-Tropsch process is one of the developing processes in the world, and es- pecially in Iran, for the conversion of synthesis gas into paraffin and olefinic prod- ucts. The purpose of this study was to investigate the effect of feed temperature and pressure on hot spot formation by means of reactor SIMULATION. The SIMULATION of GTL process FIXED BED REACTOR is carried out by MATLAB SOFTWARE package us- ing COMPUTATIONAL FLUID DYNAMICS. Also, the kinetics proposed for Fischer-Tropsch process in the literature has been compared. Two-dimensional modeling was per- formed and flow regime within the reactor was considered laminar. The finite vol- ume method was used to solve the equations. The results of the process modeling suggest that hot spot formation is more possible in bed primary section because of reaction concentration. Increasing reactor temperature resulted in an enhance- ment of reactant conversion and product yield. Raising feed temperature causes hot spot temperature to increase. According to the modeling results, the optimum temperature and pressure are equal to 570 K and 20 bar respectively. It was also found that increasing pressure and consequently temperature increased C7+ prod- uct yield, which in turn will increase the production of linear hydrocarbons.
