CATALYST AND CATALYST SUPPORT AS WELL AS METHOD OF OBTAINING THEM

摘要

Catalysts and catalyst carriers, in the form of granules having cylindrical configuration and tri-lobed cross-section provided with through-bores in correspondence of each lobe and with axes substantially parallel to each other and to the axis of the granule and also substantially equidistant one from the other. The catalysts have increased axial resistance to breakage and are obtained by compression shaping, wherein the lubricant employed is applied to the surface of the molding chamber (external lubrication).
