Method of producing gasoline
This patent describes a process of converting coal by passing a gasiform fluid upwardly through each of a fuel bed, the fluidizing gas in the second bed being a combustion-supporting gas and the fluidizing gas in the third bed comprising gas reactant with said coke to produce hydrogen and carbon monoxide. The process involves maintaining the mixture of coke and coal at coal-carbonizing temperature in said first bed to distill off volatile constituents including tar from said coal and thereby convert said coal to a residue coke. Coke from said first bed is continuously fed to the said second bed where combustion is used to raise the bed temperature substantially above the temperature in the first bed. The process continues by continuously feeding a stream of hot coke from the second bed to the first bed, and feeding a stream of hot coke from the second bed to the third bed. A gas containing hydrogen and carbon monoxide is recovered from the third bed which is catalytically synthesized to form liquid hydrocarbons. An unconverted residue part of the last-mentioned gas is used to hydrogenate the coal tar and thereby increase the yield of liquid product.
