Coal gas
Semi-coke can be used for utility boilers and coking coal in steel smelters, yields more heat than raw coal and can be converted to water gas. Water gas can be converted to oil by the Fischer–Tropsch process. Coal gas from Karrick LTC yields greater energy content than natural gas. Phenolic wastes are used by the chemical industry as feedstock for plastics, etc. Electrical power can be cogenerated at nominal equipment cost.
