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.
