Development of a high efficiency GTL process based on CO2/steam reforming of natural gas and slurry phase FT synthesis

Abstract CO 2 /steam reforming catalysts composed of noble or transient metal and MgO support and Ru-based slurry phase FT synthesis catalyst have been developed to improve the efficiency and lower the costs of GTL processes. Their high carbon and hydrogen conversion in the CO 2 /steam reforming, low methane selectivity, high olefin/paraffin ratio of the light hydrocarbons used in the FT synthesis, together with their durability, have been verified through extensive bench scale tests. Based on the performance of these catalysts, an optimal commercial scale GTL plant configuration has been developed, along with a cash flow economic evaluation that confirms the promising economics of this process. The COE (Crude Oil Equivalent) price is around US

Development of synthesis gas production catalyst and process

A CO 2 reforming catalyst and process have been developed. The commercial scale CO 2 reforming catalyst has demonstrated its activity and stability in pilot plant tests under operating conditions for the manufacture of synthesis gas with a H 2 /CO ratio of 2.0 for approximately 7,000 hours. In these tests, synthesis gas was generated by CO 2 and H 2 O reforming with high energy efficiency: low CO 2 /carbon and low H 2 O/carbon ratios in feed gas composition. Our catalyst exhibited high carbon removal characteristics with steam from the catalyst surface, which prevents carbon deposition on our CO 2 reforming catalyst.
