摘要：
A process for producing ethylene comprising introducing fuel and oxidant gas to combustion zone to produce combustion product; introducing first reactants (hydrocarbons, combustion product) to first reaction zone to produce pyrolysis product (unconverted hydrocarbons, C 2 H 2 , CO, H 2 , CO 2 , optionally C 2 H 4 ), wherein combustion product heats hydrocarbons to first temperature effective for pyrolysis; cooling pyrolysis product in quench zone to produce cooled pyrolysis product having second temperature lower than first temperature; introducing second reactants (C 2 H 6 , cooled pyrolysis product) to second reaction zone excluding catalyst to produce second product (C 2 H 4 , CO, H 2 , C 2 H 2 , CO 2 , unconverted hydrocarbons), wherein C 2 H 6 dehydrogenates to C 2 H 4 , wherein CO 2 hydrogenates to CO, wherein C 2 H 4 amount in second product is greater than in pyrolysis product, wherein second product is characterized by third temperature lower than second temperature; separating second product into C 2 H 4 &C 2 H 2 stream (C 2 H 4 , C 2 H 2 , CO, H 2 , unconverted hydrocarbons) and CO 2 stream; and recycling CO 2 stream to second reaction zone.
