Abstract
Process for the catalytic conversion of a charge incorporating at least one oxygen compound such as methanol, into olefinic hydrocarbons having 2 to 4 carbon atoms. Conversion takes place in a reactor (100), into which the charge is introduced by the pipe (20), the catalytic solid by the pipe (30) and the solid entrainment gas by the pipe (40), the reactor being connected by a pipe (1) to a co-current cyclone separator (S) making it possible to separate a solid phase from a gaseous phase containing the conversion products, which is recovered by the pipe (4). The solid phase is fed by the pipe (9) to a regenerator (R), in which the catalytic particles are at least partly regenerated before being returned by the pipe (80), connected to the pipe (30), to the reactor (100).
