Abstract: The invention relates to a solid shaped body (1) having a cylindrical form with a first base area (3), a second base area (5) and a lateral area (7), wherein the solid shaped body (1) comprises a first number of flutes (9) in the lateral area (7), each extending from the first base area (3) to the second base area (5), and a second number of openings (11), each extending from the first base area (3) to the second base area (5), and wherein the second number of openings (11) is in a range from 2 to 8, the second number of openings (11) is larger than the first number of flutes (9) and wherein a ratio between a first radius (13) of at least one flute (9) and a second radius (15) of at least one opening (11) is at least 1.15. The invention further relates to a use of the solid shaped body (1).

Abstract: A shaped catalyst body for heterogeneously catalyzed reactions of organic compounds in the gas-phase in fixed-bed reactors, containing an element from group 3 to 12 of the Periodic Table of the Elements, and having a three-lobed structure with a lateral surface around the lobes, a top cover and a bottom cover, as well as three continuous holes running from one cover side to the other cover side, wherein each hole is assigned to one lobe and wherein the cover sides have outwardly shaped arches, its production and a process for its use in the heterogeneously catalyzed reaction of an organic compound in the gas phase.

Abstract: A process for producing ethylene oxide by gas-phase oxidation of ethylene, comprising: directing a feed comprising gaseous ethylene and gaseous oxygen through a packing of individual shaped catalyst bodies, under conditions conducive to obtain a reaction mixture containing at least 2.7 vol.-% of ethylene oxide, wherein each shaped catalyst body comprises silver deposited on a refractory support and is characterized by a content of at least 20 wt.-% of silver, relative to the total weight of the shaped catalyst body; a BET surface area in the range of 1.6 to 3.0 m2/g; a first face side surface, a second face side surface and a circumferential surface with a plurality of passageways extending from the first face side surface to the second face side surface; and a uniform multilobed cross-section; and a longest direct diffusion pathway d, with 2d being in the range of 0.7 to 2.4 mm, wherein the longest diffusion pathway d is defined as the shortest distance from the geometric surface of the shaped catalyst body to a point inside the structure of the shaped catalyst body for which point the shortest distance is the largest among all points. The process allows for increased activity and/or stability of the catalyst while maintaining or increasing selectivity at high productivity.

Abstract: A three-dimensional porous catalyst, catalyst carrier or absorbent monolith of stacked strands of catalyst, catalyst carrier or absorbent material, composed of alternating layers of linear spaced-apart parallel strands, wherein the strands in alternating layers are oriented at an angle to one another, wherein the distance between inner spaced-apart parallel strands is larger than the distance between outer spaced-apart parallel strands in at least a part of the layers of the monolith.
