Title: A CATALYST ELEMENT, A PROCESS FOR THE PREPARATION THEREOF AS WELL AS A USE THEREOF
Abstract:
A catalyst element which is intended for use in a reactor for a chemical reaction where a lyophobic fluid is contacted with a lyophilic fluid for a reaction in the presence of catalyst in said element. The essential feature of the element is that it is in the form of a porous lyophobic, e.g. hydrophobic, body which has a pore size essentially below 20 νm, and is provided with a surface layer having a thickness of at most 100 νm of lyophilic, e.g. hydrophilic, catalyst particles with a size essentially below 50 νm, across part of its periphery only, said catalyst layer having been formed by sintering and/or pressing the catalyst particles into the porous, lyophobic body. Preferable shapes of said catalyst element are a plate or a so-called packing element. Furthermore, a process for the preparation of said element is disclosed, which comprises adhering a surface layer of lyophilic catalyst to part of the periphery of a porous lyophobic body by sintering and/or pressing. Finally, a use of the element is disclosed where the element is used in a reactor wherein a lyophobic fluid is contacted with a lyophilic fluid for a reaction in the presence of catalyst in said element.
