摘要： A system for heat exchange processing of particulate solid material is disclosed. The particulate solids are flowed by gravity through a housing packed with flat, internally cooled (or heated) heat exchange panels spaced apart to define generally vertical channels for the passage of the solid particulate. The panels are formed of opposed metal sheets, sealed around their edges, spot welded together in limited areas of joinder, in a predetermined pattern over their surfaces, and hydrostatically expanded in the areas between to form surfaces that are quilt-like in appearance. The panels are configured in two alternate forms such that, when a plurality of panels are assembled in a stack, the hydrostatically expanded portions of one panel are disposed opposite the areas of joinder of an adjacent panel of alternate configuration, creating a sinuous, but relatively uniform flow path for the flow of particulate solids between panels. High system efficiency is achieved by enabling adjacent panels to be spaced closer together while still avoiding the problem of "bridging" of the solid particulate material between panels.

摘要： Apparatus for regenerating spent hydrocarbon conversion catalyst. Catalyst particles in a vertically-elongated movable tapered bed are contacted with a hot oxygen-containing gas stream in order to remove, by means of combustion, coke which accumulated on the catalyst particles while they were used in a hydrocarbon conversion zone. Catalyst moves downward under the influence of gravity. The catalyst bed is tapered such that the thickness of the bed, in a dimension which is transverse to the direction of catalyst movement, varies from a minimum at the top of the tapered bed to a maximum at the bottom of the tapered bed. Gas passes through the tapered bed in a direction which is substantially transverse to the direction of catalyst movement. Substantially, all of the catalyst in the bed is in contact with the flowing gas. The variation in bed thickness causes a varying gas flow rate through the bed, from a maximum flow rate at the top of the tapered bed to a minimum flow rate at the bottom of the tapered bed and reduces the time that catalyst is exposed to high temperature gases. This flow pattern results in the delivery of oxygen in a manner which more closely matches the oxygen requirement for combustion at each point in the tapered bed. Advantages of the invention include increased coke burning capacity and longer catalyst life. Catalytic reforming is an example of a hydrocarbon conversion process in which the invention may be advantageously employed.

摘要： Apparatus for the treatment of a liquid hydrocarbon charge containing solids or solids-forming contaminants, e.g., inorganic solids, metals and asphaltenes, which includes a contactor vessel having a liquid charge inlet, a vaporizing media inlet above the charge inlet and a vapor-solids outlet. An atomizer is positioned in the charge inlet for forming small particles of the liquid charge and directing the particles of liquid in a substantially horizontal flat pattern into the contactor vessel. A premix downcomer having a dispersion grid positioned therein is located in the vaporizing media inlet for introducing a fluidized mixture of a gas dispersion media and hot circulating solid particles into the contactor vessel in a substantially vertical flat pattern to traverse the path of the liquid particles and intimately contact the liquid particles. The vapor-solids-outlet is positioned in the contactor vessel substantially opposite the liquid charge inlet to receive product vapors and entrain solid particles and rapidly pass the same into cyclones connected to the vapor-solids-outlet for separating solid particles from product vapors. A stripper vessel is located beneath the contactor vessel for receiving heavy solid particles and stripping hydrocarbons therefrom.
