Abstract (en)

[origin: EP0047509A2] 1. Process for pretreating bituminous coal, using coal, using coal which cakes only slightly or not at all, by grinding, drying and preheating, the drying and preheating being carried out under inert conditions with steam originating from the coal to be dried itself, and the coal particles then being mixed with a binder in the presence of steam, before they are subjected to tamping and coking, characterised in that the mixing period of the coal with the binder is fixed in such a way that the coal particles are coated by the binder, and the binder fulfils the function of protecting the coal from atmospheric oxygen on the way to coking.
