Abstract
A catalyst for use in the hydrotreatment of hydrocarbons comprises a carrier and at least one catalytic metal selected from vanadium, molybdenum, tungsten, nickel, cobalt and/or iron; this catalyst is in the form of a plurality of juxtaposed agglomerates of acicular platelets, oriented radially to each other. It is prepared from agglomerates of activated alumina subjected to reaction with an acid and a compound providing an anion able to combine with aluminum ions in solution.
Claims20
A catalyst comprising a carrier and at least one catalytic metal or compound of a catalytic metal, said metal or at least one of the metals being vanadium, molybdenum, tungsten, nickel, cobalt or iron, wherein said catalyst consists of a plurality of juxtaposed agglomerates each formed of a plurality of acicular platelets, the platelets of each agglomerate being oriented generally radially with respect to one another and with respect to the center of the agglomerate;
- wherein said catalyst contains a major proportion of wedge-shaped mesopores, and has an improved resistance to pore mouth plugging compared with bimodal or monomodal porous catalysts.
