Abstract

Gasification appears to be the way of processing and utilizing coal cleanly. However, currently the main issue of coal utilization is CO2 production that adversely impacts the environmental sustainability of this process. Some efforts have been made to control and reduce the CO2 emission in the atmosphere, such as using CCS (Carbon Captured and Storage) or CCU (Carbon Captured and Utilization). As a part of those efforts, this work investigates the effect of utilizing CO2 in the gasification process. Towards this aim, numerical simulations of single coal particle gasification are conducted. The benefits of adding CO2 to the gasification process compared to that of air are examined thoroughly. It is found that H2, CO and CH4 productions are increased with CO2 addition thus indicating an improvement in syngas generation from the coal gasification.
