A catalyst support structure e.g. for use in an ammonia oxidation reactor, comprising a series of primary supports () disposed above a catalyst bed, a lattice assembly disposed beneath the catalyst bed and on which the catalyst bed rests, said lattice assembly being suspended from the primary supports () by suspending means () extending through the catalyst bed. Preferably the support structure includes a static start-up burner arrangement in the form of one or more perforated tubes () adjacent the primary supports ().

Catalyst support

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. This reduces the need to preheat incoming reactants.
