Title: AN INTEGRATED PROCESS FOR CONVERSION OF METHANE TO ETHYLENE AND BENZENE
Abstract:
A process for producing ethylene and benzene comprising introducing fuel and oxidant to combustion zone to produce combustion product; introducing first reactant mixture comprising hydrocarbons and combustion product to first reaction zone, wherein combustion product heats hydrocarbons to temperature effective for pyrolysis; allowing first reactant mixture to react via pyrolysis and produce pyrolysis product comprising unconverted hydrocarbons, C2H2, C2H4, CO, H2, H2O, and CO2; cooling pyrolysis product in quench zone to form cooled pyrolysis product; introducing cooled pyrolysis product to second reaction zone; allowing a first portion of acetylene in cooled pyrolysis product to undergo hydrogenation to ethylene and a second portion of acetylene in cooled pyrolysis product to undergo trimerization to benzene, to produce second zone effluent comprising unconverted hydrocarbons, unconverted C2H2, C2H4, C6H6, CO, H2, H2O, and CO2; and separating second zone effluent into ethylene, benzene, CO2, and syngas.
