Evaluation of the Hydrodesulfurization Activity in Development of Catalysts for Demetallization of Heavy Petroleum Feedstock

Efficiency of various compositions of demetallization catalysts was studied in hydrodesulfurization of heavy crude oil. It was shown that the highest activity is observed for trimetallic NiCoMo systems, including those prepared with the use of heteropoly compounds. The influence exerted by introduct...

Description
Summary:Efficiency of various compositions of demetallization catalysts was studied in hydrodesulfurization of heavy crude oil. It was shown that the highest activity is observed for trimetallic NiCoMo systems, including those prepared with the use of heteropoly compounds. The influence exerted by introduction of up to 3 wt % ultrastable zeolite Y into the demetallization catalyst support on the activity in hydrodesulfurization reactions was examined. It was shown that addition of this zeolite makes it possible to reduce the content of sulfur in the reaction products, compared with the alumina support, and to preserve a high activity on raising the space velocity of feed.
