Abstract: In the oxidation of hydrogen sulphide contained in exhaust gases and/or organic sulphur compounds, catalysts are used which contain a) cobalt oxide and b) tungsten oxide and/or molybdenum oxide as active components and which are applied to a support of silicic acid which has an internal surface area (according to BET) of 50 to 200 m /g and a water uptake capacity of 60 to 120 ml/100 g.

Abstract: A zine oxide contg desulphurisation material is claimed, contg 20-80 wt% high surface-area Zn0 and 20-80 wt% basic zinc carbonate, mixed with water to form, dried and calcined. The surface area of the zinc oxide is min 10 m2/g, pref over 30 m2/g; technical grade zinc carbonate is used, of formula 5Zno.2C02.3H20 The oxide and carbonate are blended with water (10-60 wt%, pref 20-50%, taken as proportion of total content), blending time 1-10h, usually 1-5h. The mixt is formed, and dried, and calcined.

Abstract: Catalyst for oxidn. of SO2 to SO3 consists of a SiO2 support activated with V and alkali metal cpds. The support: has a pore vol. fraction of 10-30% pores with dia. up to 15nm, 25-60% pores with dia. 15-200 nm and 10-60% pores with a dia. of over 200nm. The catalyst is produced by mixing SiO2 of the specified pore dia. with enough liquid (water and/or H2SO4) to give a mouldable mixt., moulding, drying and calcining the moulding (at 450-650 deg.C), impregnating the calcined material with activators and drying. USE/ADVANTAGE - The catalyst has very good mechanical properties (hardness and attrition in both the fresh and aged state), high activity over a wide temp. range (ca. 380-420 deg.C) and very low pressure drop. The high activity at relatively low temp. makes it possible to reduce operating costs by using a lower temp. than usual and also reduces SO2 emissions at low temp.

Abstract: Salts of 1-10C aliphatic mono- or di-carboxylic acids with metals of normal potential >=0.5V are prepd by reactn. of the metal with the acid, opt. with water in the presence of 0.1-10% nitrate ions in the media. The process partic. for 1-4C acids is pref. carried out at 50-200 degrees C in the presence of nitrate ions from the nitrate of the metal employed, ammonium nitrate or nitric acid. Partic. for Co. Ni, Cu in catalyst prepn.
