COMALAXE CATALYST FROM SOLUTIONS BASED ON HETEROPOLYANIONS, ITS PREPARATION PROCESS AND ITS USE IN HYDROCONVERSION OF HEAVY HYDROCARBON LOADS

摘要

The present invention relates to a process for preparing catalyst (s), comprising the co-mixing of boehmite with an active phase comprising a heteropolyanion salt of the Keggin and / or Keggin type lacunaire and / or Keggin lacunaire substituted and / or Anderson and / or Strandberg, and their mixtures, having in its structure molybdenum and cobalt and / or nickel. The present invention also relates to a process for hydrotreating and / or hydroconversion of a heavy hydrocarbon feedstock in the presence of catalyst (s) prepared according to said process.
