Light gases were produced from biomass tar gasification using limonite and dolomite as catalysts. Experiments were performed in a fixed bed reactor with the gasification temperatures of 600–800 °C. Limonite gave the obvious effect on the tar gasification, and the light gases of hydrogen and carbon oxides were mainly obtained. Also, the gas yields depended on the catalytic temperature. Hydrogen yields tend to increasing with temperatures from 650 to 800 °C. The reaction equilibrium was changed by dolomite addition in the reactor system; hydrogen gas was doubled with the limonite and dolomite mixture compared to limonite only.

The catalytic effects of Zn on the yield of the gaseous products during steam gasification of lignite char were investigated by using a fixed-bed reactor. The gas composition was measured using a gas chromatography (GC). The experimental results show that Zn has catalytic effects on steam gasification and increased the yield of H2. There was an optimum content of Zn implanted into the coal above which zinc does not show further catalytic activity.

Experiments of biomass char combustion in 10%O2/90%CO2, 21%O2/79%CO2, 10%O2/90%N2 and 21%O2/79%N2 atmospheres were performed in the fixed-bed reactor system at the temperature of 800°C-1200°C. The results show that at the same temperature, NO emission is higher in O2/N2 atmosphere than that in O2/CO2 atmosphere. The higher the O2 concentration is, the higher the NO yield is. As the temperature rises, the NO yield rises at first and then decreases at the same O2 concentration and atmosphere.
