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...

This paper proposes a polygeneration system based on a multi-input chemical looping combustion system, which generates methanol and electricity, through the use of natural gas and coal. In this system, the chemical looping hydrogen (CLH) production system and the coal-based methanol production...

The broadly applicable equations for estimating learning rates of cost variables in energy systems with CO2 capture (CC) are formulated, in which the effect of overall plant efficiency upgrade on learning rates is reflected. Based on the equations, as a case study, we estimate the learning...

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...

The coal based polygeneration with CO2 capture (PG + CC) technology is expected as one of the possible options to mitigate CO2 emissions with low cost and low energy. This work assesses the cost reduction potential of PG + CC technology based on learning curve method, and finds out what...
