摘要： A catalyst support comprising at least 85 wt.-% of alpha-alumina and having a pore volume of at least 0.40 mL/g, as determined by mercury porosimetry, and a BET surface area of 0.5 to 5.0 m2/g, wherein the catalyst support is a tableted catalyst support comprising, based on the total weight of the catalyst support, less than 500 ppmw of potassium. The invention moreover relates to a process for producing a tableted alpha-alumina catalyst support, which comprises i) forming a free-flowing feed mixture comprising i-a) at least one aluminum compound which is thermally convertible to alpha-alumina, the aluminum compound comprising a transition alumina and/or an alumina hydrate; and i-b) 30 to 120 wt.-%, relative to i-a), of a pore-forming material; ii) tableting the free-flowing feed mixture to obtain a compacted body; and iii) heat treating the compacted body at a temperature of at least 1100° C., to obtain the tableted alpha-alumina catalyst support. The invention further relates to a compacted body obtained by tableting a free-flowing feed mixture which comprises, relative to the total weight of the free-flowing feed mixture, a) at least one aluminum compound which is thermally convertible to alpha-alumina, the aluminum compound comprising a transition alumina and/or an alumina hydrate; and b) 30 to 120 wt.-%, relative to a), of a pore-forming material. The invention moreover relates to a shaped catalyst body for producing ethylene oxide by gas-phase oxidation of ethylene, comprising at least 12 wt.-% of silver, relative to the total weight of the catalyst, deposited on the tableted alpha-alumina catalyst support. The invention also relates to a process for producing ethylene oxide by gas-phase oxidation of ethylene, comprising reacting ethylene and oxygen in the presence of the shaped catalyst body. The invention allows for the use of specific pore-forming materials that are particularly suitable for obtaining an advantageous pore structure while allowing for a catalyst support having high purity.
