Abstract
A reactor system includes a reactor that treats a lipid feedstock using a metal oxide catalyst to produce a treated stream comprising a bio-oil. The metal oxide catalyst includes catalyst particles having a diameter of 0.01 to 0.5 mm. The metal oxide catalyst can comprise calcium on alumina. The bio-oil has an increased proportion of transportation fuels relative to other techniques for processing lipid feedstocks.
Claims18
A method of processing a lipid feedstock, the method comprising:
- feeding a lipid feedstock to a reactor comprising at least one bed of catalyst particles, wherein the catalyst particles comprise a metal oxide on an oxide support and promote combined ketonization and pyrolysis of the lipid feedstock to produce a treated stream;
- and
- fractionating the treated stream to obtain a gaseous fraction and a liquid fraction, the liquid fraction comprising a bio-oil having a lower content of oxygen and impurities than the lipid feedstock, wherein the catalyst particles have a diameter of 0.01 mm to 5 mm.
A reactor system for processing a lipid feedstock, the reactor system comprising:
- a reactor containing at least one bed of catalyst particles, wherein the catalyst particles comprise a metal oxide on an oxide support and promote combined ketonization and pyrolysis of the lipid feedstock to produce a treated stream;
- a lipid feedstock inlet for feeding the lipid feedstock to the reactor;
- and
- a separator for receiving the treated stream from the reactor and fractionating the treated stream to obtain a gaseous fraction and a liquid fraction, the liquid fraction comprising a bio-oil having a lower content of oxygen and impurities than the lipid feedstock, wherein the catalyst particles have a diameter of 0.01 mm to 5 mm.
