Synthesis gas by gasification of Eucalyptus with the operating temperature of 550-800 ํC was studied. In this process, Eucalyptuses were used as the reactant. Steam was added with feed rate of 0.15-2.100 g/h/g of biomass as gasifying medium for synthesis gas. The effects of temperature, steam feed rate, and amount of catalyst were also studied. The objective of this research is to synthesize gas with the ratio of H[subscript 2]/CO as 1:1 which will be suit for dimethylether (DME) production. It was found that with low steam feed rate, the ratio between H[subscript 2] and CO is about 1:1. In contrast, at high steam feed rate the ratio between H[subscript 2] and CO was significantly increased. The same result was also observed for the case of temperature. The ratio between H[subscript 2] and CO was increased when temperature in reactor was increased. And the ratio was decreased when temperature was decreased. The ratio of 1:1.612 for H[subscript 2] and CO was achieved at 15 g of Eucalyptus 0.15 g/h/g of biomass 550 ํC. By adding dolomite catalyst with the same condition, it was found that the product has the ratio of H[subscript 2] and CO as 1:0.96.
