Entrained bed catalytic conversion

摘要

Process and apparatus for catalytic conversion of a feed comprising at least one oxygenated compound, such as methanol, in olefinic hydrocarbons having from 2 to 4 carbon atoms. The conversion is carried out in a reactor (100) into which the feed is introduced via the conduit (20), the catalytic solid is introduced via the conduit (30) and the gas for fluidizing the solid is introduced via the conduit (40). The reactor is connected via a conduit (1) to a cocurrent cyclonic separator (S) which makes possible the separation of a solid phase from a gas phase, containing the products of the conversion, which is recovered via the conduit (4). The solid phase is sent, via the conduit (9), to a regenerator (R) in which the catalytic particles are at least partly regenerated before being returned, via the conduit (80) connected to the conduit (30), to the reactor (100). ……
