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.

Claim (Index 1):
A process of subjecting solid biomass to thermolysis in a riser reactor having a mixing zone and an upper zone above the mixing zone, the process comprising:\n (a) introducing a catalyst into the riser reactor through a catalyst point of entry, wherein the catalyst at the catalyst point of entry has a temperature T 1 ; (b) introducing solid biomass through a biomass point of entry into the mixing zone upstream from the catalyst point of entry; (c) mixing the solid biomass and the catalyst in the mixing zone and reacting at least a portion of the solid biomass; (d) introducing catalyst into an upper zone of the reactor, wherein the temperature, T 2 , at the point of entry of the catalyst into the upper zone is less than T 1 ; (e) subjecting effluent from the mixing zone to fluidized catalytic thermolysis in the upper zone; (f) separating fluid effluent from the riser reactor into (i) a first fraction enriched in hard coke and (ii) a second fraction containing spent catalyst, soft coke and char; (g) feeding the first fraction into the mixing zone upstream from the biomass point of entry; (h) regenerating the spent catalyst in the second fraction in a regeneration unit and subjecting the soft coke and char to combustion; (i) feeding a first portion of the regenerated spent catalyst from the regeneration unit to a catalyst cooling chamber and a second portion of the regenerated catalyst from the regeneration unit to the reactor riser upstream from the mixing zone; (j) cooling the first portion of the regenerated catalyst in the catalyst cooling chamber to temperature T 2 ; and (k) introducing the cooled regenerated catalyst into the upper zone.
