Energy crisis and global wanning have advanced the widespread research on the effectively utilization of energy resources.Natural gas is one of the important fossil energy resources, and mainly used via low efficient combustion such as gas-fired plant.As a result, methane, the predominant component of natural gas, is recognized as a greenhouse gas like CO2.Besides natural gas, there is a significant amount of CO2 in CH4-riched gas resources such as biogas and coal seam gas.In addition, purified CO2 can be captured from oxyfuel combustion plant as a feedstock for chemical conversion processes for example dry reforming where the two greenhouse gases (CH4 and CO2) are reformed into syngas (a mixture of H2 and CO).As a mediate, the syngas can be converted into valuable liquid fuels and chemicals via the Fischer-Tropsch process.
