A catalyst based on natural clay, the production of such a catalyst and use of the catalyst for the hydrodemetallisation and hydroconversion of the crude and heavy residue.

摘要

The field of the invention is that of the catalysts for carrying out the hydrodemetallisation and the crude residue hydroconversion and heavy, as well as a method of preparation of such a catalyst and a method of use. / p & & p & the problem resolved is to provide such a catalyst, stable and active, based on natural clay. / p & & p & according to the invention, this objective is achieved by providing a method of manufacture of catalysts which make it possible to obtain a high content of iron dispersed at the surface of the natural clay, thanks to a grinding of the clay, in fine particles, a treatment for the acid, a washing, a partial drying, a mixture with a substance forming the pores, extrusion, and calcining at high temperature of the product is extruded. / p & & p & the invention finds an application of the right-hand side in the case of heavy crudes has a high content of nickel, vanadium, sulfur and asphaltene.
