مستخلص: Biomass gasification technology is an attractive issue because its necessity has gradually increased amid many efforts to reduce fossil fuel consumption by total substitution or certain combination masses between fossil and biomass feedstock. In this research, catalytic testing was carried out on a bubbling fluidized bed gasification system using local bentonite from Pacitan, East Java – Indonesia as the bed particle. Silica sand was selected to get comparation performance since it is commonly used as bed material in fluidized bed gasification. The Umf values are 0,011 m/s and 0.031 m/s at a pressure difference (ΔP) of around 781 Pa. Gasification in the hot model system was taking place in superficial velocity into 4 Umf with the temperature at 700°C. Bentonite gave better fluidization stability, during sampling addition without significant agglomeration formation based on ΔP activities. The tar reduction was also more effective on bentonite compared to silica sand, shown by a decrement amount of tar that could be trapped in the tar capture system. The tar that was soluble on the acetone solvent in the cold trap sharply decreased becoming 52% from 186.33 g for silica sand to 89.49 g for bentonite application. [ABSTRACT FROM AUTHOR]

مستخلص: Biomass syngas as the intermediate product of utilization biomass to liquid fuel, bio-methanol. The syngas production itself was conducted due to its environmentally clean fuel and reducing greenhouse effect. The syngas was subject to low cost catalytic methanol synthesis assessment in term of low pressure and low temperature using high local content was developed in BPPT Indonesia. The catalyst has key role to achieve optimal conditions through lowering energy activation. BPPT has developed the methanol synthesis with Cu-based impregnation catalyst using γ-Al2O3 and Activated-Carbon from palm oil shell as support catalyst. Previous experiments delivered maximum methanol product reached 8 % by operational condition 14 bar and 260°C which closed to equilibrium concentration. Further work studied more detail using internal standard and simulation by MATLAB 2014. By this condition 4% of CO was converted to methanol. Validation conducted in micromeritic at 260°C of the simulation showed maximum yield based on H2 conversion reached up to 35.39 and 31.17% at 14 and 17 bars respectively. CO conversion calculation gave maximum yield up to 36.39 and 35.45% at 14 and 17 bars respectively. [ABSTRACT FROM AUTHOR]
