Abstract
Utilization of biomass to produce gaseous, liquid and solid fuel has become the most attractive resource in Thailand. This could sustain the energy adequacy and economy stabilization at the same time. Although an indirect liquefaction of biomass via Fischer-Tropsch synthesis to produce clean liquid transportation fuels such as gasoline and diesel is extremely interesting, the program is not popular in commercial view according to a high cost of technology. However, this problem could be overcome by the development of Fischer-Tropsch catalysts and the system configurations that served the long-term with large scale production. The present research is aimed at exploring the feasibility of producing synthetic liquid fuel from bio-syngas over Ru supported on mixed oxide catalyst via Fischer-Tropsch synthesis. Attention is mainly focused on the development and improvement of Fischer-Tropsch catalysts. A series of magnesium oxide modified Ru/Al2O3 catalysts were prepared and characterized by TPD, XRD and BET technique. The catalytic behavior of catalysts prepared is elucidated in Fischer Tropsch reaction using transient and steady state conditions. The experiment has been carried out in a fixed bed reactor under the flow of CO/CO2/H2/CH4/He and CO/H2 mixture over Ru/Al2O3 and Ru/Al2O3-MgO catalyst. The preliminary of transient study reveals that the hydrogenation of pre-adsorbed CO using TPSR technique was observed at 80oC and TPSR profile shows peak maximum at ~ 200oC. The steady state reaction illustrates that the production of higher hydrocarbons (C5+) was obtained. The modification of magnesium oxide on alumina support catalyst has an effect on the catalytic performance of Ru catalysts.
