Japanese Patent JPH0631293

Y2

A process for the operation of a circulating, fluidized bed reactor is described, by which a solid particle material comprising a solid reactant material, in particular carbonaceous fuel, is introduced into the lower part of the reactor and is formed to a fast bed by means of a fluidization gas containing a gaseous reactant material, in particular oxygen, introduced into the reactor bottom, while nonreacted particles are removed from the reactor top and recirculated to the bed. By removing a predetermined fraction of the solid particle material being present in the reactor from at least one site positioned below the reactor top, subjecting it to thermal treatment and recirculating it to at least one other, lower positioned site of the bed, enhanced possibilities for process optimalization are achieved. Furthermore a fluidized bed reactor is described comprising a vertical reactor chamber (1), a first inlet (9) in the lower part (2) of the reactor chamber for introduction of solid particle material, and a second inlet (22) in the bottom of the reactor chamber for introduction of fluidization gas, and an outlet conduit (28) in the upper part (4) of the reactor chamber for removal of reactor material. Such a reactor may be used for performing the described process, when at least one further outlet conduit (5, 3a, 3b, 4) for solid particle material is provided between the first inlet (9) for solid particle material and the outlet (28) for reactor material, which outlet conduit (5, 3a, 3b, 4) via cooling or heating members (21) leads back to the reactor as at least one further inlet for solid particle material.
