Refractories for Coal Gasification

2020
Coal gasification is an important industrial chemical process and a step towards cleaner energy. The synthetic gas produced from coal gasification can be used both as a fuel and as starting material for many other synthetic chemicals. Different processes used for coal gasification is discussed.

Kinetics of Coal Gasification

1988
Coal gasification consists of coal pyrolysis and gasification of the pyrolysis products. During gasification gas/gas-, liquid/gas- and solid gas reactions can occur. All three types of reactions are treated, discussion of the heterogeneous solid/gas reaction between coal char and the gasification media (CO2, H2O, H2) is restricted to the surface ...

Coal Gasification in Europe

1979
Several European countries have been pioneers in coal gasification, both for surface gasification from coal mined underground and for in-situ gasification. With respect to the former, mention may be made of the industrial plants employing the German processes, the Koppers-Totzek and Lurgi processes, and in the latter the research conducted for 50 years

Innovative Approach to the Integrated Use of Energy Resources of Underground Coal Gasification

Solid State Phenomena, 2018
Topical issues concerning the low efficiency of underground coal mining from thin and very thin seams as well as the problems of reserves left in mine fields by the closed-down enterprises resulting in substantial coal reserve losses have been ...
