摘要： A process for producing ethylene from a carbonaceous containing feedstock the process comprising the steps of a) reforming the carbonaceous containing feedstock into a first product stream comprising carbon dioxide, carbon monoxide and hydrogen; b) fermenting the first product stream with an acetogenic anaerobic bacteria to produce a second product stream comprising ethanol; c) concentrating ethanol from the second product stream into a third product stream and; d) dehydrating ethanol in the third product stream to produce ethylene.

摘要： A method of producing ethylene and, optionally, propylene comprising: a) subjecting a feedstock to steam cracking to produce a first olefin containing stream; b) heating an ethanol containing stream with heat from a steam cracker; c) passing the heated ethanol containing stream over a dehydration catalyst at a temperature between 200 C to 500 C preferably 250 C to 450 C to produce a second olefin containing stream; d) combining the first and second olefin containing streams to give an initial product stream comprising ethylene and optionally propylene; and e) subjecting the initial product stream to purification comprising at least i) water content reduction ii) hydrogen content reduction iii) reduction of content of molecules containing 4 or more carbon atoms and iv) ethane content reduction.

摘要： Method of producing ethylene and, optionally, propylene by subjecting a feedstock to steam cracking to produce a first olefin containing stream; heating an ethanol containing stream with heat from a steam cracker; passing the heated ethanol containing stream over a dehydration catalyst at a temperature between 200 C to 500 C preferably 250 C to 450 C to produce a second olefin containing stream; and combining the first and second olefin containing streams to give an initial product stream containing ethylene and optionally propylene. The initial product stream is subjected to purification including at least i) water content reduction ii) hydrogen content reduction iii) reduction of content of molecules containing 4 or more carbon atoms and iv) ethane content reduction.
