Pollutant emissions produced during gas turbine power generation with a fuel gas from coal gasification are reduced by initially cooling the fuel gas to a temperature above the dewpoint but between 200.degree. and 400.degree. C. to condense alkalies on dust grains. In the fuel gas, HCl and HF are adsorbed on calcium carbonate and filtration removes the particulates. The fuel gas is reacted with oxygen in the presence of a carbon containing adsrobent to eliminate sulfur, and the flue gas after combustion is catalytically treated with a carbon containing adsorbent to remove nitrogen and sulfur oxides.

Process for the reduction of pollutant emissions from power stations

Coke is mixed with bituminous coal and the mixture is converted into briquettes. To obtain high-quality and high-strength briquettes, the temperature of the coke is adjusted, prior to mixing, to such a level that when the mixing takes place, the coke/coal mixture will have a precisely predetermined temperature within the scope of 400.degree.-500.degree. C. The exact temperature within this range is selected in dependence upon the characteristics of the coke and the coal.

Method of hot-briquetting mixtures of coal and coke

Fine-grained coke is produced by the degasification of fine-grained coal by a process which includes the following steps:
