摘要
New catalyst comprises a Group VIB metal and a phosphorus, boron, silicon and/or halide dopant on an alumina support in the form of beads. The support has a pore structure comprising juxtaposed agglomerates, each comprising acicular platelets oriented radially with respect to each other and the center of the agglomerate. - An INDEPENDENT CLAIM is also included for producing the catalyst by treating activa alumina beads in an aqueous medium containing an alumina-dissolving acid and a compound with an anion capable of combining with aluminum ions in solution, heating the beads at 80-250 deg. C for a few minutes to 36 hours, optionally drying the beads, thermally activating the beads at 500-1100 deg. C, and impregnating the beads with the dopant, the Group VIB metal and optionally a Group VIII metal.
