Title: Make ethylene and benzene by flash hydropyrolysis of coal in methane. [In controlled atmosphere of methane]
Abstract: On rapidly reacting methane with coal at short residence times (less than or equal to 10 sec) in an entrained tubular reactor at temperatures in the range of 825/sup 0/C 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 boiler fuel, indicates a very ample return on the investment. Analogous to the flash hydropyrolysis process for coal, this process has been termed flash methanolysis.
