NOVELTY - Regenerating catalyst used in catalytic pyrolysis of biomass, comprises (a) providing catalyst, which is used to catalyze the pyrolysis of biomass, (b) washing the catalyst with a liquid or supercritical carbon dioxide, (c) separating the catalyst from the liquid or supercritical carbon dioxide, and (d) catalytically pyrolyzing biomass using at least a portion of the separated catalyst in a reactor (110).    USE - The method is useful for regenerating catalyst, preferably coke-contaminated, fluid catalyst used: in catalytic pyrolysis of biomass for recovering minerals; and for converting biomass to hydrocarbon products (all claimed), preferably aromatics, olefins, carbon monoxide/carbon dioxide, char and coke, where the biomass is from plants, including Miscanthus, spurge, sunflower, switchgrass, hemp, corn (maize), poplar, willow, sugarcane, and oil palm (palm oil) with the roots, stems, leaves, seed husks and fruits and includes municipal wastes, green waste, byproducts of farming including animal manures, food processing wastes, sewage sludge, black liquor from wood pulp and algae, and useful as biofuel and for the production of fibers, chemicals and heat.    ADVANTAGE - The method regenerates the catalyst with improved catalyst activity and selectivity for aromatics production.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for:    (1) converting biomass to hydrocarbon products, comprising feeding biomass into a reaction chamber, pyrolyzing the biomass in the reaction chamber in the presence of a catalyst that catalyzes the pyrolysis reaction which results in coke-contaminated catalyst, and the steps (b) and (d) as above per se;    (2) an apparatus for regenerating a coke-contaminated, fluid catalyst, comprising a combustion chamber having an inlet for coke-contaminated pyrolysis catalyst, an inlet for an oxygen-containing regeneration gas connecting with a lower portion of the combustion chamber, an outlet for flue gas, an outlet for regenerated catalyst, a disengagement chamber having an inlet that is connected to the outlet of the combustion chamber, a heat exchange conduit containing heat absorbing material positioned within the combustion chamber adapted to remove heat from the combustion chamber, where the conduits are sealed with respect to the interior of the combustion chamber such that the heat-absorbing material is in indirect heat exchanging contact with the interior of the combustion chamber, and a washing chamber adapted to receive the regenerated catalyst;    (3) a catalyst for the catalytic fast pyrolysis of biomass where element or elements deposited on the catalyst during the pyrolysis reaction are partially, but not completely removed, comprising deposited elements that comprise at least 0.1% or less of the total mass of catalyst plus contaminants;    (4) a solution obtained by the washing of a used calcined catalytic fast pyrolysis catalyst with water or other solvent comprising potassium, calcium, magnesium, silicon, gallium, zinc, cobalt, iron, chromium, copper, vanadium, nickel, manganese, silver, sodium, phosphorus, tin, zirconium, niobium, yttrium, titanium, cerium and/or lanthanum; and    (5) recovering minerals from the catalytic pyrolysis of biomass, comprising separating dissolved solids from any of the solutions.
