Process for the production of ethylene and other hydrocarbons from coal
A process is claimed for the production of substantial amounts of ethylene and other hydrocarbon compounds, such as benzene from coal. Coal is reacted with methane at a temperature in the approximate range of 500/sup 0/C to 1100/sup 0/C at a partial pressure less than about 200 psig for a period of less than 10 seconds, and preferably at a temperature of approximately 850/sup 0/C, and a partial pressure of 50 psig for a period of approximately 2 seconds. Ethylene and other hydrocarbon compounds may be separated from the product stream so produced, and the methane recycled for further production of ethylene. In another embodiment, other compounds produced, such as by-product tars, may be burned to heat the recycled methane.
