Abstract:
1. An apparatus for biomass conversion comprising: a) a riser reactor having a mixing zone, an intermediate zone located above said mixing zone and forming interface with said mixing zone, and an upper zone located above said intermediate zone, wherein a biomass feed is mixed with a heat carrier material to produce a reaction mixture comprising said heat carrier material and a reaction product, which comprises oxygenated hydrocarbons; b) a biomass feed conduit connected in fluid flow communication with said mixing zone for introducing said biomass feed to said riser reactor; c) a lift gas conduit connected in fluid flow communication with said mixing zone for introducing a lift gas to said riser reactor to assist in producing a general upward flow in said riser reactor; d) a heat carrier material conduit connected in fluid flow communication with said mixing zone for introducing said heat carrier material into said riser reactor; e) a first quench stream conduit connected in fluid flow communication with said riser reactor at a location just above said interface of said mixing zone and said intermediate zone, resulting in a lower temperature in said intermediate zone as compared to said mixing zone; and f) a disengager connected in fluid flow communication with said upper zone such that said reaction mixture is received in said disengager and at least a portion of said reaction product is separated from said heat carrier material within said disengager.
