Hydrogen-rich fuel gas from rice straw via microwave-induced pyrolysis

This study aimed to research the productivity of H2-rich fuel gas from rice straw using the microwave-induced pyrolysis. The formation constituents of gas product and the mechanism of its production were also discussed. The primary components of gas product were H2, CO2, CO, and CH4, with average percentages of 50.67, 22.56, 16.09, and 7.42 vol.%, respectively. According to the TA-MS analysis, it was suggested that focused heating by microwaves made the microwave-induced pyrolysis different from the traditional pyrolysis. A chemical equation could be nearly balanced to illustrate the gas composition generated from rice straw. From the viewpoint of energy consumption, close to 60% of the input energy could be derived and utilized as bioenergy.
