Problems solved by technology

The first type involves so-called "non-regenerative" processes; the catalyst works for a long time, but its activity decreases over time, which means that the temperature of the reactor must selectivity changes

Embodiment Construction

[0053] exist figure 1 Among them, the catalyst regeneration reactor (or regenerator) is composed of a generally cylindrical container 2; the container 2 includes a combustion part CO, an oxychlorination part O and a calcination part CA. The container may take the form of a cylinder with a vertical axis, closed at its ends. The combustion section CO, the oxychlorination section O and the calcination section CA are superimposed in the reactor 1 . In reactor 1, these sections may have the same diameter, or they may have different diameters. exist figure 1 , the regenerator 1 includes two regeneration zones extending along a vertical axis from the top to the bottom of the reactor, and the two regeneration zones are configured to simultaneously regenerate two types of catalysts with different compositions. The catalyst to be regenerated is introduced via one or more conduits 3 and 3' respectively into the head of the reactor 1 in communication with storage chambers 4 and 4, so t...

Abstract

The present invention relates to a regenerator for catalysts, more particularly to a moving bed catalyst regenerator (1) comprising a vessel (2) extending in vertical direction, said vessel (2) being divided along At least two regeneration zones extending the vertical height of the vessel in which the catalyst particles move under the force of gravity, the regenerators being configured such that each regeneration zone can individually regenerate a different composition of catalyst, and wherein each regeneration zone comprises catalyst Moving successively and sequentially within: a) the combustion section (CO); b) disposed below the combustion section and comprising means for supplying catalyst from the combustion section (CO) to the oxychlorination section (O) Oxychlorination section (O); c) Calcination section (CA) provided below the oxychlorination section.

Description

technical field [0001] The present invention relates to the field of hydrocarbon conversion, more particularly to the field of catalytic reforming. The present invention relates to a regeneration reactor (or regenerator) for a catalyst, a catalytic reforming unit using a regenerator according to the present invention, and a catalytic reforming process. Background technique [0002] Reforming (or catalytic reforming) of naphtha-type hydrocarbon cuts is well known in the refining arts. Starting with these hydrocarbon fractions, the reaction can be used to produce base stocks for high octane fuels and / or aromatic fractions for petrochemicals, while providing the refinery with hydrogen necessary for other operations. [0003] The catalytic reforming process consists of the steps of contacting a hydrocarbon fraction containing paraffinic and naphthenic compounds with hydrogen and a reforming catalyst, such as a platinum-containing catalyst, and converting the paraffinic and naph...
