  • Process and apparatus for the treatment of granular solid materials in a fluidized layer
    Patent number: 4931260
    Abstract: Solid material which is carried out of a fluidized bed reactor with the gas discharged therefrom and which is separated off in a separator is returned to the reactor by way of a recycling means. To reduce problems caused by virtue of differing pressure levels within the system in the recycling operation, the pressure in the recycling means between the separator and the upper boundary of a bed of solid material which is formed in the recycling means is reduced by suction removal of gas to a pressure level which is no higher than or even lower than the lowest pressure in the separator which in turn is lower than the pressure in the reactor.
