1. A process, comprising:
(a) processing a lipid feedstock over a fluidized particulate catalyst in a gas-based stream in a fluid bed reactor to obtain a processed stream and spent catalyst comprising coke deposits, wherein the processed stream includes a gaseous fraction and a liquid fraction comprising a bio-oil, wherein the bio-oil has a lower content of oxygen and impurities as compared to the lipid feedstock;
(b) continuously introducing the spent catalyst comprising the coke deposits to a catalyst regeneration unit;
(c) continuously operating the catalyst regeneration unit to burn off the coke deposits from the spent catalyst to obtain a regenerated particulate catalyst; and
(d) continuously introducing the regenerated particulate catalyst from the catalyst regeneration unit to the fluid bed reactor.
