Abstract
A reactor with integrated heat for carrying out a chemical conversion process in the presence of a gaseous diluent supplied through one or more ports at the upper and/or lower ends of a catalytic bed through which a feed moves substantially horizontally, and a process for converting a feed, such as a hydrocarbon feed in the reactor.
Claims16
A reactor for chemical conversion in the presence of a gaseous diluent, containing a substantially vertical catalytic bed between an upper end and a lower end and comprising, in combination:
- close to the upper end of said reactor, at least one means for introducing a solid catalyst;
- means for introducing and evacuating said feed allowing its flow in a substantially horizontal manner through the catalytic bed;
- in the proximity of the lower end of said reactor, at least one means for extracting catalyst;
- at least one means for heating said feed plus added diluent, said means being internal to the reactor and traversed by said feed plus added diluent in the absence of catalyst, and separating the catalytic bed into an upstream portion and a portion downstream of said heating means relative to the direction of flow of said feed;
- wherein the reactor comprises at least one means for introducing a stream of said gaseous diluent substantially in the proximity of at least one of the upper and/or lower ends of said upstream portion of the catalytic bed, to at least reduce by-passing of said heating means by said feed plus added diluent.
A reactor for chemical conversion in the presence of a gaseous diluent, containing a substantially vertical catalytic bed between an upper end and a lower end and comprising
- close to the upper end of the reactor a solid catalyst introduction port,
- a feed introduction into the reactor and a feed removal port configured to allow feed flow in a substantially horizontal manner through the catalytic bed,
- in the proximity of the lower end of the reactor, a catalyst extraction port,
- a catalytic bed heating element which is internal to the reactor and which is traversed by feed and which separates the catalytic bed into an upstream portion and a portion downstream of said heating means relative to the direction of flow of said feed,
- and at least one gaseous diluent stream introduction port, substantially in the proximity of at least one of the upper and/or lower ends of said upstream portion of the catalytic bed, capable of reducing by-passing of the heating element by the feed plus diluent.
