The present invention relates to a catalytic reforming module (10) for converting hydrocarbons into a material including hydrogen, the module including: an inlet (11) for receiving a stream of hydrocarbons, an outlet (12) for discharging a stream of material, a heating area (13) adjacent to the inlet (11) and in which a heating honeycomb (16) is arranged, a cooling area (15) adjacent to the output (12) and in which a cooling honeycomb (18) is arranged, a reforming area (14) between the heating area (13) and the cooling area (15) in which a reforming honeycomb (17) comprising a catalyst is arranged. The present invention also relates to a catalytic reforming device for converting hydrocarbons into a material including hydrogen, the device including: a housing, at least one catalytic reforming module arranged in the housing, the housing including, for every catalytic reforming module, a hydrocarbon stream inlet channel and an outlet channel connected to the inlet and the outlet, respectively, a cooling system for placing a coolant in contact with an outer surface of the heating area of each catalytic reforming module, and a secondary cooling system for placing a secondary coolant in contact with an outer surface of the cooling area of each catalytic reforming module.
摘要:
Proposed is a process for the continuous hydrogenation of carbon-carbon double bonds in an unsaturated polymer based on a conjugated diolefin and at least one other copolymerisable monomer to produce a hydrogenated polymer, in the presence of a solvent and a homogeneous or heterogeneous catalyst, wherein said unsaturated polymer, said homogeneous or heterogeneous catalyst and hydrogen are passed through a reactor equipped with static internal elements.

Novel heat exchangers and methods of constructing the heat exchangers for use in indirect evaporative cooling applications. The evaporative apparatus for cooling comprises both a multi-stage indirect evaporative cooling heat exchanger (1074); and a multi-stage sump (1036) where each sump stage, in a one-to-one relationship. Other multi-stage heat exchangers with their associated multistage sumps can be combined, with the cooled air of a first multistage evaporative assembly feeding into the intake end of a second multistage evaporative assembly, and so on. These heat exchangers can be an entire assembly for the pre-cooling and cleaning of the air going to a gas turbine or any other air breathing device, with an air washer stage (1044) in which air is directly cooled by evaporation and where simultaneously the air is also cleaned of dust, dirt and other impurities.
摘要:
A reactor cartridge includes a plurality of spaced- apart monoliths , formed along a tube or other mandrel . Each monolith is formed of a pair of flat and corrugated metal strips , spirally wound around the tube . These strips could be made of solid or screen material . The corrugations are skewed, such that the monolith imparts a swirl to gases flowing through it . The corrugations of the strips in adjacent monoliths are oriented differently, so that successive monoliths impart different swirls to the gases, so as to promote mixing of gases and better heat transfer from the exterior to the interior of the cartridge. An insertion and removal tool simplifies the procedure for stacking such cartridges in a long pipe, or for removing cartridges from the pipe. The all-metal construction facilitates heat transfer through the entire reactor, and avoids the problems associated with packed ceramic beds.

The invention provides a flue gas desulfurization apparatus includes at least one activated carbon fiber board 20 provided in a catalyst unit 6, the board being formed by alternatingly juxtaposing one or more plate-like activated carbon fiber sheets and one or more corrugated activated carbon fiber sheets so as to provide vertically extending conduits, wherein water for producing sulfuric acid is supplied, through a capillary phenomenon, to the activated carbon fiber board 20 provided in the catalyst unit 6. The flue gas desulfurization apparatus attains removal of sulfur oxides (SO x ) by adding a minimum required amount of water to the activated carbon fiber board 20 so as to attain uniform water distribution and can reduce the amount of water required for removing sulfur oxides (SO x ).
