A device (1.1, 1.2) with a reactor vessel (2), a tube bundle (3) of multiple tubes (4), and at least one support plate (5), wherein the tube bundle (3) is disposed in the reactor vessel (2), wherein the support plate (5) is disposed in the reactor vessel (2) transversely to a longitudinal axis (6) of the reactor vessel (2), wherein each tube (4) of the tube bundle (3) is routed through a respective tube opening (7) of the support plate (5), wherein the support plate (5) supports the tubes (4) of the tube bundle (3) in the tube openings (7) transversely to the longitudinal direction of the tubes (4), wherein the support plate (5) has fluid-exchange cutouts (8) between the tube openings (7).

A method of tracking use of catalyst carriers within a tubular reactor, the tubular reactor comprising a plurality of reactor tubes, each reactor tube being configured to receive a plurality of catalyst carriers, the method comprising for each of at least some of the catalyst carriers, the steps of: marking the catalyst carrier with a carrier identifier; reading the carrier identifier when installing the catalyst carrier into a reactor tube; and accessing a database to retrieve and/or record installation data associated with the identified catalyst carrier.

The present invention relates to an arrangement of a tube-bundle reactor (1) and a sensor device (2), wherein the tube-bundle reactor (1) comprises a bundle of vertically arranged reaction tubes (3), which are open on top through upper openings and are fillable with particles of a catalyst material (4). The sensor device (2) comprises an ultrasonic sensor (6) and an evaluation device (7), wherein the ultrasonic sensor (6) is designed to emit an ultrasonic signal from above into one of the reaction tubes (3) and to receive the ultrasonic signal reflected in the reaction tube (3). The evaluation device (7) is coupled with the ultrasonic sensor (6) via a data connection (8) and is designed to ascertain the distance of the surface of the particles of the catalyst material (4) received by the one reaction tube (3) to the ultrasonic sensor (6) from the time-of-flight of the received ultrasonic signals and to ascertain a fill level height of the catalyst material (4) in the reaction tube (3) therefrom.

A reactor tube for a tubular reactor and a retaining device associated with the reactor tube; the reactor tube comprising an elongate tube defining a bore for receiving in use a catalyst and having an outlet at one end of the bore for discharging the catalyst out of the bore; the retaining device being configured to be rotatable between a first position and a second position; wherein in the first position the retaining device at least partially obstructs the outlet for retaining the catalyst within the bore; and in the second position the outlet is unobstructed sufficiently for permitting discharge of the catalyst out of the outlet.

The present disclosure relates to the aromatization of hydrocarbons with an aromatization catalyst, including methods of aromatization comprising the use of a continuous catalyst regeneration type reformer.

A process chamber can include a curved upper wall extending longitudinally from a first end portion of the reaction chamber to a second end portion of the reaction chamber. The process chamber can include a curved lower wall cooperating with the curved upper wall to at least partially define an internal cavity, the curved lower wall connected to the curved upper wall from the first end portion to the second end portion at a first side of the process chamber and at a second side of the process chamber. A rail can extend along an exterior surface of the process chamber from the first end portion to the second end portion, the rail disposed at or near a connection between the curved upper wall and the curved lower wall.
