Patent Number Title Of Patent Date Issued
8118889 Catalytic reactor February 21, 2012
A catalytic reactor (40) comprises a plurality of sheets (42) defining flow channels (44) between them. Within each flow channel (44) is a foil (46) of corrugated material whose surfaces are coated with catalytic material apart from where they contact the sheets (44). At each end of
8021633 Process an apparatus for steam-methane reforming September 20, 2011
Methane is reacted with steam, to generate carbon monoxide and hydrogen in a first catalytic reactor (14); the resulting gas mixture can then be used to perform Fisher-Tropsch synthesis in a second catalytic reactor (26). In performing the steam/methane reforming, the gas mixture is
7695694 Catalytic reactor April 13, 2010
A catalytic reactor comprises a plurality of fluid-impermeable plates defining side-by-side flow channels between them. Tight fitting within each flow channel is a sheet of corrugated material whose surfaces are coated with catalytic material. At each end of the flow channels there m
7670393 Catalytic reactor March 2, 2010
A method for causing chemical reactions between fluids, comprising the steps of arranging a plurality of metal sheets for providing first fluid flow channels adjacent to and in heat transfer contact with second fluid flow channels between adjacent ones of the metal sheets, placing cataly
7300635 Catalytic reactor November 27, 2007
A catalytic reactor comprises a plurality of fluid-impermeable plates defining flow channels between them. Tight fitting within each flow channel is a sheet of corrugated material whose surfaces are coated with catalytic material. At each end of the flow channels are headers to suppl
7234489 Valve with vortex chamber and a mechanical member to shut off flow June 26, 2007
A valve assembly (10) comprises a vortex chamber (14) with an axial outlet port (20), a main inlet port (16) for a fluid to be controlled, and a substantially tangential inlet port (25); the fluid enters through an inlet chamber (13) in which is a mechanical valve (26) movable so as to
7011101 Valve system March 14, 2006
A valve system (10) controls the fluid flow between an inlet (12) and an outlet (14). The system (10) splits the flow into two parallel flow ducts (15, 16) and recombines the flows through opposed tangential inlets (18) and (19) of a fluidic vortex valve (20) which has an axial outlet (2
6960256 Formation of small crystals November 1, 2005
Small crystals are made by mixing a solution of a desired substance with an anti-solvent in a fluidic vortex mixer in which the residence time is less than 1 s, for example 10 ms. The liquid within the fluidic vortex mixer (12) is subjected to high intensity ultrasound from a transducer
6841095 Chemical process and plant January 11, 2005
A chemical plant for performing a chemical reaction between particles of a material such as lithium metal, and a reagent such as butyl chloride in solution in hexane, in which one reaction product is a solid material, includes a reaction vessel (12). Several ultrasonic transducers (16) a
6589500 Method and apparatus for controlling uniformity of crystalline precipitates July 8, 2003
Solvent containing a product (or precursor for the product) and anti-solvent are introduced via tangential inputs respectively 17,18 of a fluidic vortex mixer 11. The emerging mix from axial outlet 20 is supplied directly to a precipitate entrapment device such as filter bed 12 so that
