Patent ID: 8071034

Claim:
A rotating fluidized bed device comprising: a reactor adapted to contact at least one fluid and a catalyst within the reactor comprising at least one cylindrical or circular chamber; a fluid removal device, wherein said fluid removing device comprises a central duct passing longitudinally through or penetrating into said cylindrical or circular chamber, the wall of said central duct comprising at least one discharge opening for centrally removing at least one fluid from the cylindrical or circular chamber via said central duct; a fluid feeding device adapted for feeding said at least one fluid that is gaseous or liquid, wherein said fluid feed device is placed around a cylindrical or circular wall of said cylindrical or circular chamber, wherein said fluid feeding device comprises fluid injectors distributed around said cylindrical or circular wall adapted to inject said at least one fluid in a succession of layers along said cylindrical or circular wall and further adapted to rotating said fluid around said central duct while entraining solid particles in a rotational movement whereby a centrifugal force thrusts said solid particles toward said cylindrical or circular wall through said layers, wherein said centrifugal force is on average at least equal to three times the force of garvity, said solid particles thereby forming said rotating fluidized bed which rotates around and at a certain distance from said central duct while sliding along said cylindrical or circular wall and while being at least partially supported by said layers of said at least one fluid which passes through said rotating fluidized bed before being removed centrally via said discharge opening of said central duct; a solid particle feeding device, said particle feeding device located on one side of said cylindrical or circular chamber; a solid particle removal device, said solid particle removal device located on an opposite side of said cylindrical or circular chamber.
