CA 2531079

A catalyst having dual functionality for the removal of arsenic and the selective hydrogenation of diolefins from monoolefin-containing hydrocarbon streams that have an arsenic concentration and a diolefin concentration, and processes for making and using such catalyst. The catalyst is a heat treated shaped mixture of a refractory oxide and a Group VIII metal that is overlaid with additional Group VIII metal.

La présente invention concerne un catalyseur qui présente une double fonctionnalité de retrait d'arsenic et d'hydrogénation sélective de dioléfines à partir de flux d'hydrocarbure monooléfiniques qui contiennent une certaine concentration d'arsenic et une certaine concentration de dioléfine. La présente invention concerne également des procédés pour produire et utiliser un tel catalyseur. Ce catalyseur est un mélange façonné, traité à chaud, d'un oxyde réfractaire et d'un métal du groupe VIII, qui est recouvert d'un métal du groupe VIII supplémentaire.
