(582cg) The Effect of CO2 on FTS over FBR System for Applications in Gtl-FPSO Process

The crude oil price on fluctuation, together with world energy demand is continuously increasing. The Gas to Liquid (GTL) process is spotlighted in energy industry and one of the promising alternative methods of petroleum fuels production technologies. In addition to the emergence of shale gas, large quantity of stranded gas has been discovered in the offshore. For better use of offshore platform, our group suggests the GTL-FPSO process based on a new concept of combining Compact GTL with Floating Production Storage and Offloading (FPSO).

In offshore stranded gas field, lots of gas fields have CO₂ content more than 30%. Steam carbon dioxide reforming (SCR) of methane which can produce synthesis gases is one of the processes where CO₂ can be utilized as a feed stock.

The synthesis gases from SCR process were adjusted for applications in GTL-FPSO system. The Co based catalyst was prepared by impregnation method and characterized by XRD, TGA, TPR and FT-IR technologies. The effect of CO₂ on Fischer-Tropsch synthesis (FTS) reaction over FBR system was investigated over the Co based catalyst and analyzed by product distributions and temperature profiles.
