The energy saving mechanism and the potential of efficiency improvement for coal to synthetic/substitute natural gas and power plant with different schemes and CO2 capture is disclosed through exergy analysis, and the effects of key parameters on exergy losses and system performance are...

A novel methanol-based power system with Chemical-Looping Combustion (CLC) is proposed in this paper. CLC system is a promising approach to greatly decrease the energy penalty for CO2 removal, where iron oxides circulate between two reactors and an inherent CO2 separation occurs. The combustion...

For both energy security and CO2 emission reduction, synthetic natural gas (SNG) production from coal is an important path to implement clean coal technologies in China. In this paper, an overview of the progress of coal to SNG technologies, including the development of catalysts, reactor...
