Abstract
Palm oil mill biomass is a promising sustainable energy source. High quality gas can be obtained in a properly designed biomass gasification process. A downdraft biomass gasification system for palm oil mill biomass is designed with a capacity of 30 kglhr. The system consists of a gasifier and a gas purification system including a cyclone separator a venturi-wet scrubber and a dryer. It is found that the system can be operated stably within the temperature range from 700C -950C. The biomass was initially pyrolyzed and the char produced was then partially gasified in the upper combustion region of the reactor and further char residue was fully gasified at the bottom region of the reactor at the temperature above 700C. The gasifier assessment performance was evaluated in terms of fuel consumption rate producer gas composition calorific value and gasification efficiency. This study indicated that under optimum operating condition a fuel gas could be produced with a production rate of 2.5 -3.0 Nm3/kg biomass and heating value of about 4500 kJlNm3 The concentration of hydrogen carbon monoxide and methane in the fuel gas produced were 6.6 12.4 and 3.7 respectively. The system carbon conversion and cold gas gasification efficiency reached above 90 and 60. Study revealed that the palm oil mill biomass could satisfactorily be gasified in the open core downdraft gasifier.
