There is a world-wide demand for clean, reliable and affordable energy. New technologies are needed to produce more oil and natural gas from ‘stranded’ locations. This work is based on gas to liquid (GTL) conversion of natural gas through Fischer-Tropsch (FT) synthesis. Fe & Co based catalysts of varying compositions were prepared in the laboratory and its performance was checked for the FT reaction. CO & H2 (from natural gas source) were mixed in the desired proportion and allowed to pass through the catalyst bed for synthesis of complex hydrocarbons, which was then condensed to yield liquid products viz. diesel,kerosene, gasoline etc. The resultant product is free of SOx and NOx and is environmental-friendly. Also, it has good fuel characteristics, which signifies the importance of GTL technology in future.
