Abstract:
A reactor includes a plurality of reaction side flow passages through which a reaction fluid flows, a catalyst (catalyst structure) disposed inside the reaction side flow passages to accelerate the reaction of the reaction fluid, a plurality of heat medium side flow passages which are alternately stacked with the reaction side flow passages, and through which a heat medium flows, and a suppression flow passage which is disposed adjacent to a surface of the reaction side flow passage, the heat medium side flow passages being not stacked on the surface, and through which flows a suppression fluid suppressing the heat dissipation to the outside from the reaction fluid flowing through the reaction side flow passage, or the heat transfer from the outside to the reaction fluid.
Abstract:
The invention relates to a reactor system, comprising a heat-exchange unit and a reaction unit that are assembled together into a structure. The heat-exchange unit has a plurality of plate or corrugated-plate heat exchangers, and is formed so as to attachable/detachable to/from the reaction unit and insertable into the latter. Accordingly, a catalyst may be attached to a heat-transfer surface of a heat exchanger by a washcoat method or the like, thus maximizing heat-transfer efficiency and enabling the easy removal or reattachment of the catalyst when the enabling the easy removal or reattachment of the catalyst at the end of the lifespan of the catalyst.

Abstract:
Embodiments of methods and apparatuses for isomerization of paraffins are provided. In one example, a method comprises the steps of separating an isomerization effluent into a product stream that comprises branched paraffins and a stabilizer overhead vapor stream that comprises HCl, H2, and C6-hydrocarbons. C6-hydrocarbons are removed from at least a portion of the stabilizer overhead vapor stream to form a HCl and H2-rich stream. An isomerization catalyst is activated using at least a portion of the HCl and H2-rich stream to form a chloride-promoted isomerization catalyst. A paraffin feed stream is contacted with the chloride-promoted isomerization catalyst in the presence of hydrogen for isomerization of the paraffins.

There is herein described a Fischer-Tropsch reactor. More particularly, there is described a Fischer-Tropsch reactor that incorporates forced flow through a small pore, thick layer, monolith supported catalyst and high levels of heat transfer that is able to operate with high levels of catalyst effectiveness. The catalyst bed (103) is supported on a distinct porous structure (101) through which the syn-gas flow is forced and the catalyst layer has a thickness of more than 200 microns.
Abstract:
Integrated Combustion Reactors (ICRs) and methods of making ICRs are described in which combustion chambers (or channels) are in direct thermal contact to reaction chambers for an endothermic reaction. Particular reactor designs are also described. Processes of conducting reactions in integrated combustion reactors are described and results presented. Some of these processes are characterized by unexpected and superior results, and/or results that can not be achieved with any prior art devices.
Abstract:
An apparatus is provided for generating mercury (II) sulfide from elemental mercury. Elemental mercury is injected into a heated and sealed reaction vessel containing vaporized sulfur. The elemental mercury reacts with at least a portion of the vaporized sulfur to form the mercury (II) sulfide within the reaction vessel. The formed mercury (II) sulfide is then unloaded from the reaction vessel.
Abstract:
The present disclosure provides for a chemical reactor which includes elongate chambers defining an arrangement and including first, second, and third elongate chambers adapted to support respective distinct first, second, and third reactor functions associated with respective first, second, and third process feeds, and a distributor arranged in fluidic communication with each of the elongate chambers and for connecting the elongate chambers to at least one fluid source. The distributor is dimensioned to produce a two-dimensional radial distribution of fluidic flow through the first, second, and third elongate chambers with respect to the first, second, and third process feeds. The chemical reactor may further include a monolith catalyst support including an N×M array of channels including the elongated chambers. The elongate chambers and the distributor may manifest an interchangeable cartridge-based system wherein the arrangement of the elongate chambers is selectably detachable from the distributor and replaceable.
