Abstract:
A radial flow reactor fluid duct distribution apparatus is presented. The apparatus includes a plate of sufficient thickness to impart strength to the fluid flow duct and is milled to have narrow slots allowing fluid to flow through the plate, while preventing the passage of catalyst through the plate.
Abstract:
A moving bed reactor system is provided. The system comprises at least one gas inlet, a distributor, a temperature control, a plurality of electrodes, and a spark control circuit. The spark control circuit drives the electrodes and generates a multi-arc discharge when the system is loaded with particles and a gas at approximately atmospheric pressure or greater is being pumped through the system. The multi-arc discharge is useful to create activated species which may improve the rate of a chemical reaction taking place in the moving bed reactor system.

Abstract:
The conversion rate of a homogeneously catalyzed reaction in which an educt is converted into a reaction product with addition or cleavage of a reaction partner or under isomerization in a liquid phase that contains an effective amount in dissolved form of a catalyst suitable for the reaction can be significantly increased in that the liquid phase containing the educt and homogeneous catalyst and, to the extent required, reaction partners [2nd] to be attached are brought into contact with a stationary or moved bed consisting of porous particles, especially particles with a pore volume of 0.1 to 3 ml/g. The liquid phase is preferably conducted in a trickle bed operation over a stationary fixed bed.
Abstract:
Gas/solids contact apparatus includes a tower-like, vertical vessel divided by internal wall structures into three axially-extending, concentric spaces. An inner space, typically of generally circular cross section and extending along the axis of the vessel, receives the gas which is to be contacted with particulate solids. An intermediate space, which may have a variety of configurations, surrounds the inner space and, during operation the contactor, contains a downwardly moving bed of solids. An outer space, typically of annular configuration, surrounds the intermediate space and serves to collect gas which flows from the inner space, generally horizontally through the moving bed of solids and then into the outer space for discharge through a gas outlet. In a preferred embodiment the moving bed of solids is contained by louvered walls, and these walls are constructed as modules which can be arranged to provide contactors having different gas and solids handling capacities.
Abstract:
A multiple cathode DC arc plasma generator arrangement is used in connection with a single anode for thermal arc plasma processing of materials. A nozzle is provided to introduce a gas in approximately the center of the multiple cathodes, towards the anode. The nozzle injects the gas into the center of the plasma column generated between the cathodes and anode to stabilize such arc and affect the self-induced electrode jets. This provides control of the heat transfer to the anode and permits feeding of particulate matter into the core of the plasma column to enhance inflight processing (melting and/or chemical reaction) of the matter. A set of gas nozzles positioned radially about the anode may be employed for feeding of particulate matter at the anode surface.

Abstract:
An improved process for continuous counter-current contact between a fluid to be treated and solid particles wherein the fluid flows through a column containing a plurality of contacting chambers each of which contains solid particles and in which intermittent transfer of the particles in a direction opposite to that of the fluid from each chamber to the chamber immediately adjacent is effected while maintaining a continuous flow of the fluid through the column.
Abstract:
In the reaction contrivance disclosed which serves the purpose of oxidizing hydrocarbons over a catalyst, with the catalyst being disposed in a casing of the contrivance. Next to an inlet into a reactor disposed in the casing, is a mixing chamber fitted rigidly, and linked with the casing of the contrivance. A separator is arranged at the outlet of the reactor. The mixing chamber provides a means of forming a reaction mixture of the reactants and the catalyst drawn from the casing and into the reactor. By virtue of this arrangement the entire surface of catalyst is in contact with the reactants and the yield of final product increases.
Abstract:
Heavy hydrocarbons are hydroprocessed in a pipe reactor and the reactor effluent separated into its vapor, liquid, and catalyst components in a multiple-zone vapor-liquid-catalyst separator. The pipe reactor may have one or more sections and the vapor-liquid-catalyst separator may be employed for intermediate separation.
