Process for catalytic cracking a pyrolysis oil
View Patent ↗A process for catalytic cracking of a pyrolysis oil derived from material comprising biomass. In one embodiment, the process comprises subjecting a feed comprising the pyrolysis oil to a hydrodeoxygenation step to prepare an at least partially deoxygenated pyrolysis oil; heating a hydrocarbon feed to a temperature in the range from equal to or more than 50° C. to equal to or less than 200° C. to prepare a preheated hydrocarbon feed; mixing the at least partially deoxygenated pyrolysis oil and the preheated hydrocarbon feed to prepare a feed mixture; and contacting the feed mixture with a catalytic cracking catalyst in a catalytic cracking reactor at a temperature of at least 400° C. to prepare a product stream containing one or more cracked products.
1. A process for catalytic cracking of a pyrolysis oil, said process comprises
contacting a feed comprising a pyrolysis oil with hydrogen and a hydrodeoxygenation catalyst to produce an at least partially deoxygenated pyrolysis oil, wherein the pyrolysis oil is derived from material comprising cellulose and/or lignocellulose;
heating a hydrocarbon feed to a temperature in the range from equal to or more than 50° C. to equal to or less than 200° C. to produce a preheated hydrocarbon feed;
mixing the at least partially deoxygenated pyrolysis oil and the preheated hydrocarbon feed to produce a feed mixture; and
contacting the feed mixture with a fluid catalytic cracking catalyst in a catalytic cracking reactor at a temperature of at least 400° C. to produce a product stream containing one or more cracked products.
2. The process of claim 1 , further comprising atomizing the feed mixture prior to contacting the feed mixture with the fluid catalytic cracking catalyst.
3. The process of claim 2 , wherein the atomizing step comprises atomizing the feed mixture in a feed nozzle.
4. The process of claim 3 , wherein the feed nozzle is a bottom entry feed nozzle or side entry feed nozzle located in a riser reactor.
5. The process of claim 1 , wherein the hydrocarbon feed comprises a petroleum derived hydrocarbon feed.
6. The process of claim 1 , wherein the hydrocarbon feed is heated to a temperature of equal to or more than 60° C. and equal to or less than 140° C.
7. The process of claim 1 , wherein the mixing step comprises mixing the at least partially deoxygenated pyrolysis oil and the preheated hydrocarbon feed in a feed nozzle.
8. The process of claim 7 , wherein the feed nozzle is a bottom entry feed nozzle or side entry feed nozzle located in a riser reactor.
9. The process of claim 1 , further comprising supplying the feed mixture to a riser reactor via one or more bottom entry nozzles and/or one or more side entry nozzle.
10. The process of claim 1 , further comprising separating the product stream into one or more product fractions.
11. The process of claim 10 , further comprising converting the one or more product fractions into one or more biofuel components and/or biochemical components.
