Abstract: Moldings are disclosed for use as a catalyst or catalyst support for hydrating olefin, such as ethylene and propylene. The moldings are based on a pyrogenically produced mixed oxide having the following physicochemical parameters:The moldings are produced by homogenizing pyrogenically produced mixed oxide as desired with water and one or more compounds selected from the group of methylcellulose, methylhydroxyethylcellulose, wax, polyethylene glycol, magnesium stearate or aluminium stearate; drying the product at a temperature of 70-150° C.; optionally comminuting to yield a powder; optionally compression molding the powder to yield moldings; and performing heat treatment for a period of 0.5 to 10 hours at a temperature of 400 to 1200° C. Prior to drying, the mixture may also be subjected to kneading and/or shaping processes and extruded.

Abstract: A molded body based on pyrogenic mixed oxide and having the physical properties: external diameter 0.8-25 mm, BET-surface 5-400 m /g, pore volume 0.2-1.8 ml/g, breaking strength 5-350 N, is new. The composition contains: at least two oxides from the group SiO2, Al2O3, TiO2, and ZrO2 in any combination, with the exception of mixed SiO2-AlO3 oxide, which contains more than 75 wt.% SiO2, content of other constituents less than 1 wt.%, bulk weight 250-1500 g/liter. Independent claims are included for: (1) preparation of the molded body having the above physical properties and composition, by homogenization of the pyrogenic mixed oxide with one or more compounds selected from: methylcellulose, methylhydroxyethylcellulose, wax, polyethylene glycol, Mg or al stearate, with addition of water at 70-150 deg C, drying, optional grinding to a powder, compacting of the powder to a molded body, and tempering over 0.5-10 hours at 400-11200 deg C; and (2) a phosphoric acid catalyst on a formed inorganic support containing 1-50 wt.% H3PO4, based on the total catalyst weight.
