Abstract: Biomass is converted into a bio-oil containing stream in a riser reactor having multiple ports for the entry of fresh catalyst. Hard coke formed during pyrolysis may be separated from the riser effluent fraction containing which contains spent catalyst, soft coke and char. The separated hard coke may then be fed back into the riser reactor. The riser reactor may further have a cooling media which quenches the rapid heat transfer to the biomass during pyrolysis of the biomass in the mixing zone of the riser.

Abstract: Biomass is converted into a bio-oil containing stream in a riser reactor containing a cooling media. The cooling media quenches the rapid heat transfer to the biomass during cracking of the biomass in the mixing zone of the riser. By lowering the temperature to which the mixing zone effluent is exposed, production of carbon monoxide and light gases is decreased during thermolysis of the biomass.
