摘要： A catalyst charge for ammonia oxidation, including the Andrussow process, comprises a first stage ammonia oxidation catalyst capable of oxidizing 20 to 99% of designed ammonia throughput, to produce a first stage product gas comprising unreacted ammonia, oxygen and nitrogen oxides, and a second stage ammonia oxidation catalyst capable of completing the oxidation of unreacted ammonia. Low levels of nitrous oxide are produced an extended campaign lengths may be seen.

摘要： A method is described for producing a high temperature shift catalyst, not requiring a reduction step prior to use, by precipitating a composition containing divalent and trivalent iron compounds and a modifier metal selected from trivalent chromium and/or manganese compounds from an aqueous solution containing iron and modifier metal salts with a base, and forming the resultant precipitate into shaped catalyst units, without exposing said precipitate to an oxidizing atmosphere at temperatures above 200° C.

摘要： A fixed bed containing a particulate catalyst or sorbent material (10) subject to operation at high temperature having a shaped boundary member (16) inclined to the direction of fluid flow through the bed that maintains the depth of said catalyst or sorbent at the boundary of the bed through a series of thermal expansion-thermal contraction cycles is described. By maintaining bed depth, the shaped boundary member (16) can prevent bypass of, e.g. ammonia through a bed of particulate ammonia oxidation catalyst.
