ABSTRACT:
A continuous, hydrocarbonization process wherein a dense-phase flow of coal particles is indirectly preheated in the absence of oxygen to a temperature below the temperature at which the coal particles undergo plastic transformation, introduced into the bottom of a vertical fluid-bed reaction zone at a high velocity in a vertically upwards direction and reacted with hydrogen to yield char, liquid and gaseous products. The hydrocarbonization reaction is conducted at a temperature of 480.degree. C-600.degree. C, a hydrogen partial pressure of from about 100 p.s.i. to about 1200 p.s.i. and an average solids residence time of 1 to about 30 minutes, preferably about 5 to about 60 minutes. A high velocity enables the coal particles entering the reaction zone to rapidly and uniformly distribute themselves at their preheated temperature within a matrix of nonagglomerating particles within the reaction zone, thus preventing agglomeration of the coal particles in the fluid-bed reaction zone.
