  • Publication number: 20160177200
    Abstract: The present disclosure is directed to a process for hydroprocessing a hydrocarbon feedstock. The process utilizes a horizontal bubble reactor for slurry hydroprocessing of a heavy hydrocarbon feedstock having an API Gravity of less than 20, where the reactor is fitted with one or more vapor-only outlets to provide intrinsic separation of catalyst from product.

  • Patent number: 6897178
    Abstract: Catalysts for the water gas shift reaction contain a variety of late transition metals. The catalytic compositions contain a late transition metal carried on a support which is a carbide, nitride, or mixed carbide nitride of a group 6 metal such as molybdenum, tungsten, and mixtures thereof. The late transition metal includes ruthenium, cobalt, nickel, palladium, platinum, copper, silver, or gold. The water gas shift reaction may be catalyzed by contacting a gaseous stream containing carbon monoxide and water with such a solid catalyst composition. In some embodiments, the catalysts are several times more active than known commercial catalysts for the water gas shift reaction.
