REDUCING SULPHUR CONTENT OF COAL

摘要

A process for reducing the sulfur content of coal comprising the steps of: 1) contacting an aqueous slurry of water and sulfur-containing coal particles at elevated temperature with oxygen under conditions such that the resulting coal can form coal-oil agglomerates; 2) contacting the slurry of coal particles with hydrocarbon oil to form coal-oil agglomerates; and 3) recovering coal-oil agglomerates wherein the coal has reduced sulfur content. r
