    摘要: Bulk and supported catalysts are prepared from an aqueous slurry containing a catalytically active material and a binder. The slurry is either coated onto a support and dried to form a porous, high surface area phase containing the catalytically active material, or reduced to a paste-like consistency, molded and dried to form a bulk catalyst. The processes and catalysts may be employed in various catalytic chemical processes to achieve high effectiveness factor of the catalytically active material while achieving a lower pressure drop.

    摘要: A method is disclosed for maintaining a volumetric gas to liquid ratio in a segmented gas/liquid flow along a reactor of monolithic catalyst beds in series. The present invention includes the steps of: initiating the segmented gas/liquid flow at a first end of the reactor by introducing feed liquid and feed gas both at a predetermined volume and a predetermined flow rate; injecting an additional amount of gas at least once into any of the spaces between catalyst beds; and combining the segments of the segmented gas/liquid flow at a second end of the reactor. The injection of gas is controlled such that the segmented gas/liquid flow can be maintained near or at the Taylor regime.

    摘要: Liquid hydrocarbons such as gas oil feedstocks are hydrotreated by passing feedstreams comprising a hydrogen-containing gas and the liquid hydrocarbons through a catalyst bed comprising honeycomb or similarly structured monolithic hydrotreating catalysts at controlled superficial liquid linear velocities and gas:liquid feedstream ratios; good hydrotreating selectivity and high one-pass conversion rates for sulfur and other heteroatoms are provided.
