A catalyst having a good stability and a high capacity of the containment of the metals, used for the demetallization of heavy crudes, and method of manufacturing

摘要

The field of the invention is that of the catalysts used to extract the sulphur, nitrogen, the metals of contamination, the asphaltene and the conradson carbon, of the crude and heavy residue / p & & p & the problem resolved consists in providing a catalyst is active and stable, having a pore distribution more favorable to its effectiveness in the hydrotreatment of heavy crude residue and / p & & p & according to the invention, the catalyst is obtained by comprised, on an alumina plate at least one metal of group vib and a metal of group viii of the periodic classification table, as well as a phosphorus oxide, in percentages specific. / p & & p & the invention concerns also a process for manufacturing the said catalyst, as well as a method of application of the harmonics of the catalyst for hydrotreatment of heavy crude residue and
