Fluidized bed reactor and associated hydropyrolysis process

The present invention provides a process comprising a.) supplying a biomass feedstock, a fluidizing gas having hydrogen, and a catalyst recycle stream having a deoxygenating catalyst to a mixing zone of a fluidized bed reactor; b.) allowing the biomass feedstock, the fluidizing gas and the deoxygenating catalyst to move upward through the fluidized bed reactor from the mixing zone to a bulk reactor zone; c.) allowing the biomass feedstock to contact the deoxygenation catalyst in the bulk reactor zone of the fluidized bed reactor in the presence of the fluidizing gas to produce a hydropyrolysis reactor output comprising at least one non-condensable gas, a partially deoxygenated hydropyrolysis product and char; and d.) withdrawing at least a portion of the deoxygenating catalyst from the bulk reactor zone to form the catalyst recycle stream, the catalyst recycle stream being supplied to the mixing zone in step a). 本发明提供了一种方法，该方法包括a.)将生物质原料、具有氢气的流化气体和具有脱氧催化剂的催化剂再循环流供应到流化床反应器的混合区；b.)允许该生物质原料、该流化气体和该脱氧催化剂穿过该流化床反应器
