DEVICE AND METHOD FOR CATALYTIC GAS PHASE REACTIONS AND THEIR APPLICATION Russian patent published in 2013 - IPC B01J8/00 B01J15/00 C01B21/26 B01J8/02 B01J19/00 C01B21/28 

FIELD: process engineering.

SUBSTANCE: invention relates to catalytic exothermic gas-phase reactions and reactor to this end. Proposed reactor comprises inlet zone 1, reaction zone 2 including at least one catalyst 4, and product gas outlet zone 3, along arranged along raw gas flow. In said inlet zone 1 or inlet zone 1 and reaction zone 2, reactor has coolant transfer device composed of isolating shell 6 to decrease heat transfer from reaction zone 2 to inlet zone, hence, to decrease risks of premature ignition of raw gas mix or to rule out undesirable side reactions in inlet zone 1. Reactor inner walls in inlet zone 1 or inlet zone and reaction zone 2 consist of inert material.

EFFECT: possibility to use for ammonium oxidation in, for example, nitric acid plants.
