INTRODUCTION

Numerous experimental studies have persuasively shown the advantages of hydrocarbon fuel productions from synthesis gas via the Fisher-Tropsch synthesis (FTS) in slurry reactors 1., 2.. The key advantages are: the effective temperature control and, as a result, almost temperature gradientless operation that permits to achieve high selectivity of C3 + hydrocarbons formation, a possibility to operate at low H2/CO ratios without catalyst deactivation, lower operation expenses compare to tubular or

CONCLUSION

The mathematical model of processes occurring in the FTS slurry reactors is proposed. We have estimated the coefficients of the mathematical model and shown that reaction of synthesis carried out in the transition region, when both the catalyst activity and gas-liquid mass transfer affect. The optimal conditions for the FTS were obtained numerically.

    The LTFT processes produce predominantly longer chain linear paraffins. After mild hydro-treatment to convert olefins and oxygenates to paraffins the linear oils and various grades of linear waxes are sold at high prices [51]. FT synthesis always produces a wide range of olefins, paraffins and oxygenated products such as alcohols, aldehydes, acids and ketones regardless of reaction conditions.
