FIELD: chemistry.
SUBSTANCE: invention relates to a catalytic installation suitable for use in a tubular reactor, in combination with a granular catalyst, in particular, with catalysts suitable for use in catalytic stream reforming processes. Catalytic installation is described, located in the vertical reaction tube. Installation contains a structured catalyst at the top of the reaction tube. Granular catalyst under the said structured catalyst in the lower part of the said reaction tube. Catalyst carrier arrangement is located between the structured catalyst and the particulate catalyst. Device of the carrier of the catalyst contains a cylindrical body having a first end adapted for connection with a structured catalyst, and a second end. Cylindrical body has a diameter of 70–90 % of the internal diameter of the tube, and a length/diameter ratio in the range of 0.5–2.5.
EFFECT: invention provides a reduction in unwanted overheating of the reaction tube walls.
