Ceramic cyclone for a fluid catalytic fractionation unit

摘要

Cyclone (10) for the mechanical separation of particles in suspension in a gas, in particular intended for a fluid catalytic fragmentation unit, said cyclone comprising the following elements: - a separation chamber (101), - a duct (102) of inlet leading into the chamber (101), - a gas outlet duct (103) located in the upper portion of the chamber (101) and - a particulate outlet duct (104) located in the lower portion of the chamber (101), characterized in that each element of the cyclone is constituted by a ceramic material and the ceramic material comprises a ceramic matrix selected from silicon carbide, SiC, boron carbide, B4C, silicon nitride Si3N4, aluminum nitride, AlN, nitride of boron, BN, alumina, Al2O3, or mixtures of these, incorporating carbon fibers or ceramic fibers or a mixture of these fibers in this ceramic matrix.
