Abstract

This paper proposes a polygeneration system based on 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 production (CLH) system and the coal based methanol production system is integrated. The high quality fuel, natural gas, is used to prove the conversion ratio of coal. The Gibbs energy of the two kinds of fuels is fully used. Benefits from the chemical looping process, the 27% of CO2 can be captured without energy penalty. With the same outputs of methanol and electricity, the energy saving ratio of the new system is about 12%. Based on the exergy analyses, it is disclose that the integration of synthetic utilization of natural gas and coal plays a significant role in reducing the exergy destruction of the new system. The promising results obtained may lead to a clean coal technology that will utilize natural gas and coal more efficiently and economically.
