摘要:
Interior microchannels within microchannel apparatus are uniformly coated. Remarkably, these uniform coatings are formed from materials that are applied to the interior microchannels after an apparatus has been assembled or manufactured. Coatings can be made uniform along the length of a microchannel, in the corner of a microchannel, and/or throughout numerous microchannels in an array of microchannels. Techniques for tailoring the application of washcoats onto microchannels is also described.
摘要:
A method for determining the maximum allowable working pressure of a microchannel device, particularly a diffusion-bonded, shim-based microchannel device operating at a temperature greater to or equal to a base material threshold temperature where significant creep may predominate, and when employing non-traditional materials of construction, when non-traditional fabrication or joining methods are used, or when spurious artifacts arise.
摘要:
A forklift having a frame supported by front and rear wheels is mounted on a carrier by inserting its forks into pockets mounted on the frame of the carrier vehicle and lifting the wheels of the forklift off the ground. A pair of wheel abutments on the underside of the carrier serve as abutments for the front wheels of the forklift to prevent its forward movement. A combined lock and support structure connected to the frame of the carrier prevents separation of the forklift from the carrier after the hydraulic system of the forklift is neutralized and all pressure on the forks, carriage, and mast are relieved of support forces.

摘要:
A fork lift truck takes less storage space when its support wheels are raised from operative position to storage position parallel with the mast of the truck. To further minimize the space taken up by the stored truck, the rotation of the wheels upward to inoperative position uses a camming surface which also telescopingly cams the wheel and support arms inward toward the mast.
摘要:
A method of loading material within a microchannel device, the method comprising: (a) loading particulates into a plurality of microchannels; and, (b) ultrasonically packing the particulates into the plurality of microchannels using a portable, compact ultrasonic densification unit.
摘要:
Methods of oxidative dehydrogenation are described. Surprisingly, Pd and Au alloys of Pt have been discovered to be superior for oxidative dehydrogenation in microchannels. Methods of forming these catalysts via an electroless plating methodology are also described. An apparatus design that minimizes heat transfer to the apparatus' exterior is also described.
摘要:
New designs, methods and processes are described that in which laminated devices and configured in a style named the “ortho” style. To form a device in the ortho style, plates or sheets are machined to have apertures and then stacked together such that the apertures connect and fluid can flow through the device in a direction that is substantially parallel to the direction of sheet thickness. Various laminated devices and processes using them are also described. For example, devices in which non-rectangular microchannels conform around reaction chambers or other bodies that need to be heated or cooled, are described. Features that separate or trip boundary layer and enhance heat transfer are also described.
摘要:
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.
