  • Chemical reactor and process
    Patent number: 4882444
    Abstract: In an exothermic reaction the reactants are passed through a fixed catalyst bed through which heat exchange tubes pass, reactants are flowed transversely to the tubes, heated by a first group of tubes and cooled by a second group of tubes, heat exchange fluid being passed from the first group of tubes to the second.
