Abstract

Use of lignocellulosic biomass as an alternative; renewable and sustainable source of energy has fulfilled part of the growing demand for energy in developed countries. Amongst various technologies applied to convert biomass wastes to biofuel and bioenergy; biomass gasification has attracted considerable attention. In this work; gasification of palm empty fruit bunch as a potential lignocellulosic waste was investigated in a pilot scale air-blown fluidized bed. Silica sand and dolomite were used as bed material. The bed temperature was varied in the range of 650 to 1050 oC. The quality of the producer gas (H2223 were achieved using silica sand and dolomite. Maximum dry gas yield of 1.84 and 1.79 (Nm3gas/kg biomass); carbon conversion of 91 and 85% and cold gas efficiency of 69 and 65% were obtained for silica sand and dolomite; respectively. Although the quality of the produced gas was considerably improved at high temperatures; however formation of the bed agglomerates was the major concern at temperatures above 800 and 850 oC for silica sand and sawdust.
