DOWNFLOW LIPID CONVERSION WITH UPFLOW CATALYST REGENERATION

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 reactor system includes a catalyst zone in which the metal oxide catalyst reacts with the lipid feedstock to produce the treated stream. the reactor system operates in a reaction mode, during which the lipid feedstock flows in a downward direction through the metal oxide catalyst to produce the treated stream. alternately, the reactor also operates in a regeneration mode, during which coke is burned from the metal oxide catalyst thereby regenerating the metal oxide catalyst. in one aspect, a regeneration mode pressure is less than a reaction mode pressure within the reactor to fluidize the catalyst.
