Production of desulfurized liquids and gases from coal

Abstract

Abstract An integrated process for simultaneously recovering liquid and gaseous products from coal. A slurry is formed from crushed coal and recycled oil and is introduced to a three-zone reactor along with a hydrocracking catalyst and sand, the latter of which acts as a conveying medium. In the first zone, coal liquids are extracted and conveyed to a fractionation unit. In the second zone, the carbon coked on the solids is gasified with air creating a producer gas which flows upwardly countercurrent to the downward flow of the aforementioned mixture and supplying heat for the extraction stage. In the third stage, the remaining carbon is gasified with oxygen and carbon dioxide to a substantially nitrogen-free carbon monoxide. The carbon monoxide is desulfurized in a metal oxide bed.
