Claim:
1. A process for carrying out an oxidation on a sprayable feed including a crude dehydration product of natural hexose as a furanic substrate to be oxidized and a catalytically effective combination of cobalt, manganese, and bromide components for catalyzing the oxidation of the furanic substrate, comprising the steps of: acid dehydrating a natural hexose to provide a crude dehydration product as a furanic substrate to be oxidized; directly incorporating the crude dehydration product into the sprayable feed; spraying the feed into a reactor vessel; supplying oxygen or an oxygen-containing gas as an oxidant to the reactor vessel; reacting the furanic substrate and the oxidant in the presence of the cobalt, manganese and bromide components to form 2,5-furandicarboxylic acid; and managing the exothermic temperature rise due to the reaction, through a selection and control of the operating pressure within the reactor vessel.
