ABSTRACT:
This invention makes possible substantially continuous flow of uniformly distributed hydrogen and hydrocarbon liquid across a densely packed catalyst bed which substantially fills the entire volume of a reactor vessel. Catalyst are selected to be essentially the same density, shape and size at a design feed rate of liquids and gas to prevent ebullation of the packed catalyst bed at the design feed rates. The liquid and gas components of the hydrocarbon feed stream flow into the bed of catalyst and a quenching medium, which is preferably a liquid, is injected into the bed of catalyst. Injection of a liquid quench reduces the gas component of the hydrocarbon feed stream while simultaneously increasing the residence time and reducing the liquid velocity of the liquid component of the hydrocarbon feed stream within the substantially packed bed of catalyst. Injection of a liquid quench also increases penetration and contact of the liquid component into and on the surface area of the catalyst while simultaneously decreasing the viscosity of the liquid component. An apparatus for quenching in hydroprocessing of a hydrocarbon feed stream.
