Abstract A new reactor system, in which two adjacent fluidized beds exchange solids but not gases, has been developed, and patented. The partition between the two fluidized beds is designed to permit the movement of solids in both directions, but to provide an effective seal against gas mixing. There are no moving parts. High circulation rates can be achieved, and can easily be controlled. Gas mixing at less than the 2% level can be achieved without a neutral blanketing gas to seal the interface. It should be possible to achieve zero leakage with a blanketing gas. The reactor system was developed as an oil shale retort in which the combustor exchanges solids with the retort - but in which the combustion gases and product gases are kept separate. However, the system has many potential applications including gasification and pyrolysis of coal, hydrogen production, heat exchange in difficult conditions and SO2 removal by absorption or adsorption.
