Abstract: A process for the continuous preparation of hydroxylammonium salts by catalytic reduction of nitrogen monoxide by means of hydrogen in a dilute aqueous solution of mineral acid in a plurality of reaction stages connected in series comprises dividing the incoming stream of dilute aqueous solution of mineral acid into at least two substreams before it is fed into the plurality of reaction stages connected in series, feeding a first of these substreams to the first reaction stage, feeding a second of these substreams to a reaction stage other than the first, where the inflow of dilute aqueous solution of mineral acid into the plurality of reaction stages connected in series is controlled by means of the pH in this reaction stage other than the first.

Abstract: Production of a spinel monolith catalyst comprises forming or coating a molded body, especially a monolith with a surface active composition; impregnating the monolith with a solution of a compound of group 5b elements in the form of oxides or salts; and drying and optionally calcining. Production of a spinel monolith catalyst comprises forming or coating a molded body, especially a monolith with a surface active composition of formula: AxB(1-x)E2O4 (where: A = copper, half of which can be replaced by cobalt, iron, nickel manganese or chromium; B = zinc, magnesium, calcium, zirconium, cerium, tin, titanium, vanadium, molybdenum or tungsten; E = aluminum, half of which can be replaced by Fe2O3, Cr2O3, Ga2O3 or La2O3; and x = 0-0.9); impregnating the monolith with a solution of a compound of group 5b elements in the form of oxides or salts; and drying and optionally calcining.
