A process for beneficiation of coal by selective caking.

摘要

A process is disclosed for beneficiation of coal by selective caking, in which process a caking mixture is employed consisting of: - one or more solvents selected among the light hydrocarbons having boiling points not higher than 70 DEG C; - one or more non-ionic additives selected among oil-soluble propoxylated or propoxylated-ethoxylated phenolic or alkylphenolic compounds; - possibly one or more heavy co-caking agents selected among coal-derived oils having boiling points between 200 DEG C and 400 DEG C, or the residual products of petroleum refining, or mixtures thereof.
