Abstract

Un catalizador con la doble funcionalidad de remover arsénico y de hidrogenar selectivamente las diolefinas, contenidas en una corriente de hidrocarburos que contiene monolefinas con arsénico y diolefinas, y los procesos para elaborar y usar dicho catalizador. El catalizador es una mezcla tratada con calor de un óxido refractario y de un metal del grupo VIII que contiene una sobrecapa de otra metal del grupo VIII.
