Abstract
A process for thermally cracking carbonaceous substances, such as coal, is described, comprising: rapidly heating the carbonaceous substance to 500.degree. to 950.degree. C. in an atmosphere consisting essentially of hydrogen gas at a pressure of 35 to 250 kg/cm.sup.2 (gauge pressure) in the presence of at least one compound selected from the group consisting of halides, sulfates, nitrates, phosphates, carbonates, hydroxides, and oxides of Group VIII metal elements of the Periodic Table. The process increases the cracking of the carbonaceous substances and accelerates the conversion of the carbonaceous substances into gas and liquid products, greatly increasing the yields of the gasoline fraction and light oils.
