APPARATUS FOR THE GASIFICATION OF COAL

摘要

Gasification of coal by hydrogenation to produce CH4 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.
