Medium-load power generating station with an integrated coal gasification plant, a gas turbine power generating station part connected to the coal gasification plant, a steam power generating station part connected to the raw gas heat exchanger plant of the coal gasification plant, a methanol synthesis plant having a plurality of modules connected in parallel to each other, and a purified gas distribution system which connects the methanol synthesis plant to the gas turbine power generating station part and which includes a purified gas continuous flow interim storage plant and is connected on the gas side to the raw gas heat exchanger plant. The methanol synthesis plant is associated, for hydrogen enrichment, to a 'cooler-saturator loop' which is connected to the raw gas heat exchanger plant and consists of the saturator, a converting plant, cooler and following gas purification plant. In one mode of operation, a water electrolysis plant is associated with the methanol synthesis plant and its hydrogen line is connected to the methanol synthesis plant, and its oxygen line is connected to the coal gasifier.

Power generating plant with an integrated coal gasification plant

Combination method for the gasification of coal and the reduction of metal ores involving hydrogenation gasification of coal to produce hydrocarbons and a coke component. The coke is subjected to steam gasification and the gas therefrom used to reduce ores. Spent gas from the reduction is treated to convert CO in the gas to H.sub.2 and CO.sub.2. The CO.sub.2 is scrubbed out and the H.sub.2 is sent to the hydrogenation gasification to hydrogenate the coal.

Combination method and device for gasifying coal and for reducing metal

Gasification of coal by hydrogenation to produce CH.sub.4 hydrocarbons, and by steam to produce hydrogen. Forming a medium-grain and a small-grain fractions from coal. Hydrogenating the volatile and readily reactive components of part of the small-grain fraction to form hydrocarbons and coke. Mixing the coke with the other part of the small-grain fraction. Forming briquets from the mixture. Mixing the briquets with medium size coal fraction and steam gasifying to produce hydrogen. The hydrogentation is preferably carried out in a fluidized bed operation and the steam gasification in a fixed-bed operation.
