Abstract: IN A PROCESS FOR THE PREPARATION OF ACROLEIN OR ACRYLIC ACID OR A MIXTURE THEREOF FROM PROPANE, THE PROPANE IS SUBJECTED, IN A FIRST REACTION STAGE, TO A PARTIAL DEHYDROGENATION UNDER HETEROGENEOUS CATALYSIS TO GIVE PROPANE, OF THE COMPONENTS CONTAINED IN THE PRODUCT GAS MIXTURE FORMED IN THE FIRST REACTION STAGE OTHER THAN PROPENE AND PROPANE AT LEAST A PORTION OF THE MOLECULAR HYDROGEN PRESENT IS THEN SEPARATED OFF ROM SAID MIXTURE AND THE PRODUCT GAS MIXTURE IS THEN USED FOR THE PREPARATION OF ACROLEIN AND/OR ACRYLIC ACID GAS-PHASE CATALYTIC PROPYLENE OXIDATION, MOLECULAR NITROGEN BEING PRESENT FOR DILUTING THE REACTION GAS MIXTURE DURING THE PROPYLENE OXIDATION.

Abstract: A reactor, used for reactions between liquid/gas, or gases/liquids/solids, and has a vertical longitudinal axis with an educt feed pipe in the upper part of the reactor. Incoming gas (3) enters via an aperture in the base (5), and is distributed via a gas distributor module (9) that consists solely of straight pipes (14, 15). The gas distributor module has no curved or bent pipes. All pipes within the module are cylindrical and of circular cross section. Pipe sections are joined at right angles to each other. Horizontal distributor pipes (15) are at 40-90% of reactor chamber (4) depth.
