 Abstract
The paper presents a novel technique that enhances the hydrogen yield of conventional biomass steam gasification. This is done by integrating
the gasification and absorption reactions. The method involves steam gasification of a carbonaceous fuel (biomass) in presence of a CO2
sorbent. Experiments were conducted by gasifying pine bark in presence of calcium oxide. The gasification was carried out at atmospheric
pressure in the temperature range 500.700 ◦C. The hydrogen yield, total gas yield and carbon conversion efficiency increased by 48.6%, 62.2%
and 83.5%, respectively, in the presence of sorbent at a gasification temperature of 600 ◦C. This was attributed to the reforming of tars and
hydrocarbons in the raw product gas in presence of calcium oxide. The CO and CH4 concentrations in the product gas were lower while using
the sorbent. The calcium oxide played the dual role of sorbent and catalyst.
