Abstract

1382991 Fluidised bed process UCB SA MG SLINKO 11 Jan 1972 [12 Jan 1971] 1485/71 Heading BIF [Also in Division C2] A catalytic fluidised bed process comprises passing at least one gaseous reactant through a fluidised bed of catalyst particles present in a reactor, the fluidised bed containing a plurality of filling elements therein to promote homogenity of the bed, and heat exchange means being provided which maintains the temperature of the fluidised bed at a desired value during the process, wherein the filling elements each consist of a winding- of rigid material, e.g. stainless steel the total volume of rigid material of said windings representing 2-12% of the total volume occupied by the said fluidised bed and the said rigid material and the speed of displacement of the gaseous reactant(s) through the fluidised bed is from 0.25 to 0.95 times the speed that would cause the entrainment of the particles of the fluidised bed out of the reactor. The synthesis of acrylonitrile from propylene, ammonia and oxygen is exemplified.
