A method of controlling the solids circulation between a downflow reactor and an entrained bed reactor is disclosed wherein at least some of the solids are transferred from the downflow reactor to a crossflow fluidized bed through a first seal leg, wherein the crossflow fluidized bed has a baffle separating the crossflow fluidized bed into two zones. Then the solids are transferred from the crossflow fluidized bed to the entrained bed reactor, and the solids are transferred from the entrained bed reactor to the downflow reactor through a second seal leg. The solids circulation rate is controlled by adjusting the rate of fluidizing gas entering the crossflow fluidized bed.
