摘要： A method of forming a liquefied coal product having a lower sulfur percent by weight than the solid coal from which it is derived comprising the steps as follows:(a) providing solid coal having a sulfur percent by weight of a particle size less than about 14 Tyler mesh,(b) providing calcium oxide of a particle size less than about 40 Tyler mesh,(c) mixing said solid coal and said calcium oxide with liquefaction solvent to form a liquefaction mixture,(d) hydrogenating and heating said liquefaction mixture to at least about 750.degree. F. forming a liquefied coal product having residual coal solids and calcium sulfide solids,said liquefied coal product having a liquefied coal product sulfur percent by weight, which is less than said solid coal sulfur percent by weight.
