Abstract
In a process for producing anhydrides in a tubular reactor, gaseous reactants are passed downwardly through at least one reactor tube to a catalyst carrier where they pass into a passage defined by an inner perforated wall of a catalyst container before passing radially through the catalyst bed towards a perforated outer container wall. The reaction occurs as gas contacts the catalyst. Unreacted reactant and product exits the container though the perforated outer wall and then upwardly between an inner surface of a container skirt and the outer wall of the container and then over the end of the skirt and caused to flow downwardly between the outer surface of the skirt and the inner surface of the reactor tube where heat transfer takes place. These steps are repeated at any subsequent catalyst carrier product is then removed from the reactor outlet.
