Disclosed is a reactor and process for exothermic vapour phase reaction, wherein the reactor (1; 101) comprises a pressure vessel (2; 102) having inlet means (3; 103) for reactant(s) and outlet means (4; 104) for products; a plurality of beds (5; 105) with heterogeneous catalyst, each bed supported by means (6; 106); a vapour collection chamber (9; 109) and a vapour redistribution chamber (10; 110) between successive pair(s) of beds for redistribution of vapourous reaction mixture over the inlet of the next bed; a diaphragm (11; 111) separating the vapour collection chamber (9; 109) from the vapour redistribution chamber; at least one pair of nested trough members extending at least partially across the diaphragm, each comprising an inner trough member (14; 114) having one or more apertures (18; 118), an outer trough (20; 120) having one or more apertures (21; 121) and a quench gas conduit (15; 115) provided with apertures (17; 117); the apertures (18; 118; 21; 121; 17; 117) arranged to provide a tortuous pathway for the flow of vapour and quench gas. |
