In addition to a primary emphasis as a near term, cost effective, clean boiler fuel, solid solvent refined coal (SRC‐I) has unique potential as an intermediate to produce products of vital importance to several of the basic industries in the U.S.A. These include the aluminium, steel, chemical, and petroleum industries, in addition to the electric utilities. Solid SRC can be hydrotreated catalytically to produce liquid fuels and aromatic chemicals using technology which is commercially proven on petroleum residuums. At comparable product cost, these liquids would be lower in sulphur and nitrogen than competitive one‐stage coal liquefaction processes. Thus, coal can be converted to products to serve the major uses of petroleum, i.e. transportation fuels and fuel oils which will facilitate displacing the imported petroleum currently serving these markets. Secondly, solid SRC can be coked and calcined to produce anode quality coke for the aluminium industry. Currently, carbon anodes, which are an essential component of the Hall smelting process, are being produced from petroleum based coke. Thirdly, metallurgical Formcoke used in steel industry blast furnaces can be produced by processing solid SRC with hydrocarbonized non‐metallurgical grade coals. the process using SRC as the binder is continuous, environmentally acceptable, and economic as compared to the batch coke over route using coking coals. Solid SRC, with its uniform properties relatively independent of feed coal, could solve many of the raw materials and fuel requirements of the aluminium, steel, and petroleum fuels industries.
