Abstract: The application relates to a process for the recovery of molybdenum and/or vanadium from used catalysts or oxide residues of such catalysts, by a selective leaching of the ground catalysts with solutions of aqueous oxalic acid at 50 to 150 DEG C, in particular at 90 to 120 DEG C. The leaching and grinding can also be performed simultaneously in an intensively stirred and heated container using grinding bodies.

Abstract: Process for the preparation of methyl formate by reaction of methanol on copper-containing catalysts at elevated temperature and in the gas phase by using a catalyst containing, apart from 30 to 80% by weight of copper, calculated as CuO, 20 to 70% by weight of magnesium silicates, calculated as MgO plus SiO2 in which the MgO/SiO2 molar ratio is 0.3 to 1.5, and which can be additionally doped with the metals zinc, chromium and/or barium in amounts of, in each case, up to 1.5% by weight, calculated as ZnO, Cr2O3 and BaO.

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.
