| titleOfInvention | Supported catalyst, process for its production, and its use in oxychlorination of ethylene |
| abstract | A supported catalyst comprises: (a) 0.5 - 15 wt.% of one or more Cu-II compounds, the quantitative amounts referring to the copper metal; (b) 0.1 - 8 wt.% of one or more alkali metal compounds, the quantitative amounts referring to the alkali metal; (c) 0.1 - 10 wt.% of an oxide mixture comprising (c1) 80 - 95 mole % of oxides of cerite rare earths with atomic Nos. 57 to 62, except promethium, and (c2) 5 - 20 mole % of zirconium dioxide, where (c1) and (c2) together total 100 mole % and the quantitative amount of (c) refers to the oxides of the mixture; and (d) the remainder up to 100 wt.% is .gamma.- and/or ~- aluminium oxide as support material; wherein (e) the support material (d) has a total pore volume in the range from 0.65 to 1.2 cm3/g, and (f) the supported catalyst is present in the form of cylindrical hollow bodies having at least one passage channel, the ratio of height h to external diameter d e being less than 1.5 for diameters d e of up to 6 mm, and the ratio h/d e being less than 0.6 for diameter d e greater than 6 mm. The supported catalyst provides an increase in reaction conversion and selectively, while exhibiting increased service life. The supported catalysts are particularly useful for the oxychlorination of ethylene, and processes are provided for its manufacture. |
