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.
Claims15
A process for converting a lipid feedstock to a treated stream, the process comprising:
- providing the lipid feedstock to a reactor such that the lipid feedstock reacts with at least one bed of catalyst particles producing the treated stream, wherein the catalyst particles have a diameter of 0.01 to 0.5 mm and comprise calcium oxide on an alumina support;
- 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.
A reactor system for converting a lipid feedstock to a treated stream, the reactor system comprising:
- a reactor configured to contain at least one bed of catalyst particles, wherein the catalyst particles have a diameter of 0.01 to 0.5 mm, and comprise calcium oxide on an alumina support;
- a lipid feedstock inlet for feeding the lipid feedstock to the reactor wherein the lipid feedstock reacts with the catalyst particles and the treated stream is produced;
- 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.
