Coal Gasification - an overview ScienceDirect Topics

This coal gas is a mixed gas of hydrogen and carbon monoxide called synthesis gas. Gas synthesis research has been conducted for quite some time, and the basic reaction formula of general gasification is as follows. (5.21)Coal → H2 + CmHn + Char (C) (5.22)C + O2 → CO2. (5.23)C + 1/2CO2 → CO. (5.24)C + CO2 → 2CO.
