ABSTRACT:
A liquid product containing a high percentage of phenolic compounds is obtained from coal by the hydrocarbonization of coal in a fluidizing bed in the presence of hydrogen. The hydrocarbonization is conducted at a temperature of 480.degree.-600.degree. C. and a hydrogen partial pressure of from about 100 to about 1,200 psi and an average solids residence time of 1 to about 30 minutes. Oxidation of the coal even by atmospheric air must be substantially avoided to maximize phenolic production. Oxidizing coal reduces the tar and the phenolic yield by as much as 50 percent in some instances. Subbituminous, especially non-agglomerating varieties are especially preferred coals.
