Flash methanolysis of coal for the synthesis and production of ethylene, benzene and liquid hydrocarbons
Abstract
On rapidly reacting methane with coal at short residence times (< 10 sec) in an entrained tubular reactor at temperatures in the range of 825/sup 0/ to 900/sup 0/C and pressures of 50 to 100 psi, significant yields of ethylene, BTX, and light oils are formed. The yield of ethylene increases strongly with decreasing pressure. There appears to be no net consumption of methane. A preliminary economic analysis of a process for production of the above feedstocks from coal, recycling the methane and using the residual char as a boiler fuel indicates a very ample return on the investment.
