Abstract

Raise of energy demand, in line with the rate of population growth is always followed by waste volume increasing. Where the largest percentage comes from organic waste, it is potentially utilized as raw material of biomass mixture for emission reduction efforts on fuel conversion from waste energy. The main objective of this paper is to study the characteristic of co-gasification, especially gasification temperature, lower heating value and gas emission, on the performance of the biomass gasification process in a downdraft fixed bed gasifier. In this study, organic waste used twigs of rice husks in the pelletization as raw materials on combustion technology Downdraft Gassifier. Methods were carried out by co-gasification techniques between rice husk, mixture and RH (rice husk) pellet. Where syngas testing is done direct measurement on burner with TCD gas chromatography. The flaming pyrolisis temperature in the reactor is 700 C – 750o C and the temperature in the combustion zone is 900 C – 1100o C. The result of the syntetic gas testing obtained the highest lower heating value in rice husk pellet 100% composition at 2.68 MJ/Nm3. The lower the calorific value of the raw material in the fuel composition, the smaller the LHV syngas output, where an increase in RH pellets will increase the LHV syngas value. This resulted in visually low tar content and low ash particles in all compositions of about 30% of the initial mass of each composition according to the experimental literature, with the lowest ash in the 100% rice husk pellet composition predicting yield.
