1. Coal properties and main chemical reactions
1.1 Typical composition of coals by source
The composition of coals varies considerably from one type to another, and has an influence on gasification reactions. Global analyses (proximate) give an indication of coal type and quality:
The first synthesis gas was produced by coal pyrolysis in the late 18th century. Gasification became a commercial process in 1812 with The London Gas, Light and Coke Company.
The first applications were lighting, followed by heating. Electricity generation is a much more recent development.
Coal gasification developed rapidly between 1940 and 1955, before the use of natural gas. During this period, it was developed mainly in the Federal Republic...
