NOVELTY - Converting biomass to products comprises: contacting the biomass with hydrogen in the presence of a fluidized bed of hydropyrolysis catalyst in a reactor vessel under hydropyrolysis conditions; removing products and char from the reactor vessel, where the contacting and removing steps are performed for a period of time such that the fresh hydropyrolysis catalyst attrits in the fluidized bed to form small catalyst particles; and removing at least a portion of the small catalyst particles with the products and char, where the products leave the fluidized bed at an exit bed velocity.    USE - The process is useful for converting biomass to products, preferably liquid products, which are useful for gasoline, diesel fuel, transportation fuels, jet fuel and/or other valuable liquid hydrocarbon products, and producing hydrocarbons from biomass.    ADVANTAGE - The process is capable of economically converting the biomass to valuable products.    DETAILED DESCRIPTION - Converting biomass to products comprises: contacting the biomass with hydrogen in the presence of a fluidized bed of hydropyrolysis catalyst in a reactor vessel under hydropyrolysis conditions; removing products and char from the reactor vessel, where the contacting and removing steps are performed for a period of time such that the fresh hydropyrolysis catalyst attrits in the fluidized bed to form small catalyst particles; and removing at least a portion of the small catalyst particles with the products and char, where the products leave the fluidized bed at an exit bed velocity, the char has a settling velocity that is less than the exit bed velocity and hydropyrolysis catalyst has a settling velocity that is greater than the exit bed velocity, and the small catalyst particles have a settling velocity that is less than the exit bed velocity.
