2021-7-8 The conversion of coal to gaseous fuels has roots in commercial coal carbonisation work, that spanned almost 300 years. With the advent of the oil embargo and consequential drastic increases in oil prices, as well as serious shortages in natural gas in the early 1970's, the interest in coal gasification was revived with great intensity

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 ...
