Methane (CH4) and carbon dioxide (CO2) are the components of gas produced by biomass pyrolysis gasification and biogas from bioreactor. These two gases are known as the main greenhouse gases that affect world climate change. This study has tried to investigate the characteristics of microwave heating reformation that seeks to convert the produced gas into valuable fuel energy. Through microwave reforming, a carbon receptor was used as two types of sludge char and commercial activated carbon. Regarding CH4 reformation, H2 was produced via thermal decomposition with generated carbon (C) that adsorbs on the active catalytic plate and reduces the active catalytic reaction. In the case of CO2 reformation, CO was produced via reaction with the carbon on the surface of the carbon receptor; this can solve the problem of removing the adsorbed carbon from the carbon receptor. Using the sludge char as the carbon receptor showed higher gas yields for H2 and CO than the commercial activated carbon receptor, while giving a comparatively higher heating value for the sludge char receptor. In addition, in the cases of lower temperature and residence time in the carbon captor, the CH4 and CO2 conversions and the reforming gas yields had lower values.
