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:
A reactor configured to release hydrogen from a hydrogen-bearing, liquid compound, having a reactor vessel which comprises at least one body with metallic support structure. A solid, highly porous coating is applied on said at least one body which comprises catalytically acting substances for the release of hydrogen from the liquid, hydrogen-bearing compound, wherein the at least one body with metallic support structure comprises at least one cutout with a volume that remains the same or becomes larger from along a cross-sectional dimension extending from bottom to top, based on the reactor vessel.
Abstract:
A fluid hammer/siren can operate in fast valve mode with no leakage flow. A stream reactor and process for chemical reaction acceleration provides a flow of liquid or gas forming jets, streams, vortices, or walls of cavities/bubbles that collide with each other or with other liquid, solid, or gaseous interfaces with energies (defined as the sum of molecular kinetic plus thermal energy) in excess of a chemical reaction activation energy. Wastewater treatment methods accelerate suspended particles to high velocity in a fluid flow and then decelerate rapidly by stopping the flow for accelerated inertial-force driven separation.

The invention is directed to a bimetallic catalyst system adapted for the manufacture of xylenes, a process for making said catalyst system, and to the process of manufacture of xylenes using said catalyst system, providing, in embodiments, improved selectivity by at least one of higher ethylene saturation and low xylene loss, decreased susceptibility to poisoning from feedstream impurities, and ability to operate at less severe conditions.
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.
Abstract:
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:
A method of reacting compounds can include directing a liquid into a helical constrained flow (37) having an inner circumferential flow surface and an outer circumferential flow surface. The helical constrained flow (37) can be formed around an axial interior volume (38). At least a portion of the helical constrained flow can be exposed to a sparging portion (35) to allow a fluid to be sparged into the liquid along the helical constrained flow (37). The fluid reactant can be sparged through the helical constrained flow so as to form a fluid product.
