The device comprises a support (20) and at least one basket (22A to 22E) carried by said support (20). The basket (22A to 22E) comprises an upstream apertured wall (60) and a downstream apertured wall (62) together defining an intermediate space (70) for receiving the solid product (24). The upstream apertured wall (60) defines, opposite the intermediate space (70), a feed passage (90) for the upstream flow, and the downstream apertured wall (62) defines, opposite the intermediate space (70), a discharge passage (92) for a treated flow. The upstream apertured wall (60) and the downstream apertured wall (62) are mounted in such a way that said apertured walls can be moved freely in relation to one another and in relation to the support (20), on a given expansion path.
摘要:
The invention relates to a reactor for the catalytic conversion of reaction media (1) in a reaction chamber (4) with the aid of a catalyst, wherein the reactor is equipped with at least one plate heat exchanger (6) in a reactor container (2). The plate heat exchanger (6) is substantially composed of heat-exchange plates (5) separated from each other by packings (7). The heat-exchange plates (5) define, between each other, the reaction chamber (4) through which the reaction medium (1) flows. According to the invention, the respective packing (7) is constructed as a catalyst support (7) that is structurally independent of the plate heat exchanger (6). In this case, the support (7) in question may be optionally inserted into a plate interstice (4) defining the reaction chamber (4) and removed again therefrom.

A reactor (10) comprises a stack of metal sheets (12, 14, 15) arranged to define first and second flow channels (16, 17) within the stack, the first and second flow channels being arranged alternately within the stack, with removable catalyst-carrying gas-permeable non-structural elements (22, 24) within each flow channel in which a reaction is to be performed, wherein the first flow channels are for an exothermic reaction and the second flow channels are for an endothermic reaction. The channels (20) at each end of the stack are such that no heat is generated within them. They may be non-flow channels (20).
摘要:
An insertion apparatus is provided for inserting at least one catalytic insert into each of a multiplicity of reactor channels. The apparatus comprises a magazine configured to locate a multiplicity of catalytic inserts, a guide element for guiding the movement of a catalytic insert as it is inserted into the reaction channel, and a pushing member to push a catalytic insert out of the magazine, through the guide element, and into a reactor channel. An automated method for inserting catalytic inserts into reactor channels is also provided. The method comprises the steps of: aligning the insert with a reaction channel, and pushing the insert through a guide element into the channel.
摘要:
A heat exchanger or chemical reactor comprising a heat exchange body defining a plurality of flow passages and a removable insert defining secondary heat exchanger surfaces retained within at least one of the flow passages by insert retention means. The insert comprises one or more plate(s) having perforations to define discreet fluid flow channels extending across the plate(s) and wherein said one or more of the plates is provided with a carrier for a catalyst or adsorbent.

A compact heat exchanger and/or fluid mixing means comprises a bonded stack of plates, the stack comprising at least one group of plates, the group comprising one or more perforated plates (10) sandwiched between a pair of primary separator plates (40, 62, 64), characterised in that each perforated plate (10) has perforations (14) arranged in rows across the plate in a first direction, with a land (16) between each adjacent pair of perforations (14) in a row and with ribs (18) between adjacent rows, the lands (16) forming barriers to flow in a first direction across the plate and the ribs (18) forming barriers to flow in a second direction across the plate, the second direction being normal to the first direction, the ribs (18) having vents (20) through a portion of their thickness, the vents (20) extending from one side of a rib (18) to the other side in the second direction, whereby flow channels are provided through the vents (20) and the flow channels lying between each adjacent pair of lands (16) provide a flow passage to cross the plates in the second direction, the passageways in the group of plates being separated from passageways in any adjacent group of plates by one of the separator plates (40).
摘要:
A reactor includes: a reaction-side flow passage (210) through which a fluid as a reaction object flows; and a catalyst structure (300) provided in the reaction-side flow passage (210). The catalyst structure (300)includes: a body part (310) formed in a raised and depressed plate shape to partition the reaction-side flow passage into a plurality of flow passages disposed side by side in a direction perpendicular to a flow direction of the fluid; a catalyst carried on the body part (310) to promote a reaction of the fluid; and one or more communication holes (grooves) (330) to make the plurality of flow passages partitioned by the body part (310) communicate with each other.
摘要:
An automated insertion apparatus (30) is provided for inserting at least one insert (20) into each of a multiplicity of reactor channels (17). The apparatus comprises means (57) at a feed position to support a magazine (38) which holds a multiplicity of inserts (20), and a transport mechanism (50) defining at least two support channels (60) each configured to hold a single insert (20), and means to transport each support channel (60) repeatedly between an input location adjacent to the feed position and an output location (52), and means to feed one insert (20) from a magazine (38) at the feed position into a support channel (60) of the transport mechanism (50) at the input location. The apparatus also includes a transfer mechanism (56) to push an insert (20) into a reactor channel (17), and an alignment mechanism (32, 34) to ensure that the insert that is being inserted is aligned with the reactor channel. The transfer mechanism (56) is adjacent to the output location. The transport mechanism (50) may be a rotary drum.
