IMPROVED PROCESS FOR HETEROGENEOUS SYNTHESIS AND RELATED REACTORS

摘要

Improved process for heterogeneous synthesis and related reactors according to which the synthesis catalyst is distributed in three catalytic beds (C1, C22, C3) either axial-radial or radial, control of the temperature between beds being effected by means of fresh quench gas (4) between the first and the second bed and by means of indirect cooling with an exchanger (S2) between the second and the third bed of the gas leaving the second bed, using fresh gas which is heated inside the tubes of said exchanger.
