This invention makes possible substantially continuous flow of uniformly distributed hydrogen and hydrocarbon liquid across a densely packed catalyst bed to fill substantially the entire volume of a reactor vessel by introducing the fluids as alternate annular rings of gas and liquid at a rate insufficient to levitate the bed and with catalyst selected by a density, shape and size at a design feed rate of liquids and gas to prevent ebulation of the packed bed at the design feed rates. Catalysts are selected by measuring bed expansion in a large pilot plant run with hydrocarbon, hydrogen, and catalyst at the design pressures and flow velocities. The liquid and gas components of the feed flow into the bed in alternate annular rings across the full area of the bed. At the desired flow rate, such catalyst continually flows in a plug-like manner downwardly through the vessel by introducing fresh catalyst at the top of the bed by laminarly flowing such catalyst in a liquid stream on a periodic or semicontinuous basis. Catalyst is similarly removed by laminarly flowing catalyst particles in a liquid stream out of the bottom of the bed.

On-stream catalyst replacement hydroprocessing method wherein an upstream mixture of hydrogen and hydrocarbon liquid counter flows through a downwardly moving bed of hydroprocessing catalyst in a reactor vessel. The mixed feed stream of hydrogen and liquid hydrocarbon components enters a surge zone between the lower end of the reactor and a plenum zone to form a common pool under a conical support for the lower end of the downflowing catalyst bed. The mixed feed enters the plenum chamber through a plurality of passageways extending downwardly from the plenum zone to the same depth adjacent the lower end of the surge zone so that the liquid component normally prevents hydrogen from establishing independent paths before entering the plenum zone. Separation of the hydrogen and hydrocarbon liquid components from the mixed feed is thus assured to occur in the plenum zone directly below the pervious conical support to form a plurality of stepped concentric local reservoir rings under the conical support. Such rings are spaced apart sufficiently to create adjacent and alternate separate feed rings of hydrogen and hydrocarbon liquid.

A process for the catalytic conversion of various chlorinated hydrocarbon byproducts and waste products especially to less chlorinated, useful or salable products, in which a chlorinated hydrocarbon feedstock containing two or more chlorines is reacted with hydrogen in the presence of a catalyst consisting essentially of an active hydrogenating metal component such as platinum in elemental or compound form, and a surface segregating metal component such as copper in elemental or compound form on a support.

A flow injection analysis flow cell suitable for precipitation titration flow injection analysis wherein the flow cell has a chamber and a dammed space within the chamber. The carrier containing the precipitate is flowed into the dammed space and overflows it into the chamber. The flow cell is designed so that a chemical sensing probe can be inserted into the dammed space to allow precipitation titration flow injection analysis with reduced problems of flow cell plugging.

A process for converting a chlorinated alkene feedstock including two or more chlorines to reaction products including a less-chlorinated alkene in a commercially substantial proportion, comprising reacting the chlorinated alkene feedstock with hydrogen in the presence of a catalyst consisting essentially of a Group VIII metal other than rhodium, palladium or ruthenium and a Group IB metal on a support.
