Process for preparing catalysts and catalyst carriers

摘要

In the present invention, there is disclosed a process for preparing catalysts and catalyst carriers, in the form of granules having a hollow cylindrical shape with circular or polygonal multi-lobed cross-section with through-bores in correspondence with the various lobes and in which the through-bores have axes which are substantially parallel between themselves and to the axis of the granule wherein the preparation process comprises compression shaping of a powder comprising the catalyst or carrier components or precursors using a lubricant deposited on the surface of the mold and the shaping apparatus and subsequent subjecting the shaped granules of a catalyst or a catalyst carrier to heat treatment activation wherein the step of the compression shaping is carried out in the presence of a lubricant placed onto the surface of a mold and device.
