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.

A method of controlling the solids circulation between a downflow coal gasification reactor and an entrained bed combustion reactor comprising: (a) transferring at least some of said solids from said downflow reactor to a crossflow fluidized bed through at least one seal leg, wherein said crossflow fluidized bed has a baffle separating the crossflow fluidized bed into two zones, wherein said two zones comprise a first zone and a second zone, and wherein said solids are transferred from said downflow reactor to the first zone of said crossflow fluidized bed; (b) transferring said solids over said baffle from said first zone to said second zone; (c) transferring said solids from said second zone of said crossflow fluidized bed to said entrained bed reactor; and (d) transferring said solids from said entrained bed reactor to said downflow reactor through a second seal leg; controlling the solids circulation rate by adjusting the rate of fluidizing gas entering said crossflow fluidized bed.
