摘要: Pulverized coal is converted by means of a gaseous mixture and partial oxidation into synthesis gas which is subsequently utilized as a feedstock for the production of hydrocarbons. A gaseous mixture containing non-converted synthesis gas and low boiling hydrocarbons is separated from the higher boiling hydrocarbons and recycled to the coal conversion step.
