Abstract: A fixed-bed tubular reactor that extends between first and second ends and includes a bed of catalyst powder confined in an annular space defined by an outer wall of a hollow tube and an inner wall of a hollow insert, which comprises a distribution chamber and a collection chamber. The tubular reactor comprises at least one make-up chamber separated from the at least one distribution chamber and the at least one collection chamber by at least one first dividing wall. The at least one make-up chamber has an inlet port for at least one make-up fluid, which differs from the reactive gases, at the first end and an outlet port for the at least one make-up fluid at the second end.

Abstract: A fixed-bed tubular reactor that extends between first and second ends and includes a bed of catalyst powder confined in an annular space located between an outer wall of a hollow tube and an inner wall of a hollow insert, which comprises a distribution chamber and a collection chamber. The inner wall is covered with a permselective membrane allowing partial removal of at least one reaction product, in that it comprises at least one make-up chamber separated from the at least one distribution chamber and collecting chamber by at least one first dividing wall. The at least one make-up chamber includes an inlet port for at least one make-up fluid and an outlet port for the at least one make-up fluid.

Abstract: A tubular reactor comprises a catalytic powder bed confined in an annular space delimited by an inner wall and an outer wall, the insert comprises a distribution chamber and a collection chamber, separated by at least one first partition wall, the distribution chamber comprising distribution compartments separated from one another by second partition walls, each distribution compartment and the collection chamber comprising, respectively, an intake opening and a discharge opening, the inner wall comprises distributing openings and a collecting opening, each distributing opening enabling the distribution of a gas towards the annular space, and the collecting opening enabling the collection of the gas distributed in the annular space by the collection chamber.

Abstract: A tubular reactor comprises a powder bed in an annular space delimited by a first wall, of a hollow tube and a second wall, of a hollow insert, the hollow insert comprises a distribution chamber and a collection chamber, separated by at least one partition wall, the distribution chamber is provided with a plurality of distributing openings whereas the collection chamber is provided with a collecting opening, the plurality of distributing openings and the collecting opening are formed at the second wall, the distributing openings enabling the distribution of a gas capable of being admitted through the intake opening from the distribution chamber—towards the annular space, and the collecting opening enabling the collection of the gas distributed in the annular space by the collection chamber.

Abstract: According to an aspect, this invention relates to a cooling device for a disc brake, the device extending in a longitudinal direction and comprising a first portion configured to surround the discs of the brake, intended for being arranged facing the side surfaces of the brake discs and configured to capture, by irradiation and/or convection, the heat generated by the discs during the friction. The cooling device further includes a second portion, secured and thermally coupled to the first portion, offset in the longitudinal direction relative to the first portion, and provided with tins extending radially relative to the longitudinal direction and configured to dissipate the heat captured by the first portion, by convection and/or irradiation, into the ambient air.
