Catalytic combustion of ultra-low heat value fuel over 0.5%Pd/ZrO2/γ-Al2O3 was investigated to offer an opportunity for scientifically using such fuel sources. The experimental studies were performed using single fuel, synthetic mixtures and different kinds of gasified biomasses, respectively. The effects of varied combustible gas concentration, inlet temperature and flow velocity on the conversion rate were also studied. The results showed that the ignition temperature of 1.4% CH4 over the catalyst used is lower 210 °C than that in the oxidation absence of catalyst. Conversion of CH4 increased with decreasing flow velocity and increasing combustible gas concentration. The influence of the flow velocity on the conversation is more significant when further increasing the CH4 concentration to a certain degree. The ignition temperature for CO, H2, CH4 decreased with increasing concentration, and the specific order is TCH4, TCO, TH2. The experimental data showed that the influence of H2 is very obvious for CH4 combustion-supporting character by adding different concentration of H2. Among the experiments of three kinds of gasified biomasses, the catalytic combustion characteristics of wood chip gas is best, followed by grape seed gas and cotton wood gas. These studies would provide the experimental analysis and technical support for catalytic combustion technology application in ultra-low heat value fuel.
