Coal Gasification - an overview | ScienceDirect Topics

In Environmental Impacts of Coal Mining & Utilization, 1987. 4.1 Basic Principles. Coal gasification means the complete conversion of coal into gas using heterogeneous gas solid reactions. The main process is the reaction of the carbon of coal with steam, at pressures below 10 MPa and temperatures above 750°C, to form a “synthesis gas” containing mainly CO and H 2 with smaller amounts of ...

Clean Coal Technology related to Coal

Clean Coal Technology related to Coal Gasification. Coal is more abundant and cheaper than oil and natural gas, but it exhausts high carbon dioxide gas (CO 2) and sulfur content of the environment load at the time of the use. Clean coal technology (CCT), which uses coal in high efficiency and clean, is a key technology to reduce the discharge ...
