    Abstract: A composition comprising a fluid, and a material dispersed in the fluid, the material made up of particles having a complex three dimensional surface area such as a sharp blade-like surface, the particles having an aspect ratio larger than 0.7 for promoting kinetic boundary layer mixing in a non-linear-viscosity zone. The composition may further include an additive dispersed in the fluid. The fluid may be a thermopolymer material. A method of extruding the fluid includes feeding the fluid into an extruder, feeding additives into the extruder, feeding a material into the extruder, passing the material through a mixing zone in the extruder to disperse the material within the fluid wherein the material migrates to a boundary layer of the fluid to promote kinetic mixing of the additives within the fluid, the kinetic mixing taking place in a non-linear viscosity zone.

  • Patent number: 8202360
    Abstract: The present invention aims to provide an adsorbent with superior adsorption performance of 20 wt % or more in a humidity range of 5 to 60 wt % by using a low-cost reagent as the raw material. Aluminum sulfate is used as the Al source, the respective aqueous solutions are mixed to achieve a Si/Al molar ratio of 0.70 to 1.0 in the mixed solution, the pH is adjusted to be 6 to 9 with acid or alkali, the solution is heated at 90 to 110° C. and subsequently subject to desalination treatment in order to synthesize an amorphous aluminum silicate. The obtained amorphous aluminum silicate yields a superior water vapor adsorption performance of 20 wt % or more in a relative humidity of 60%, and can be used as an adsorbent for desiccant air conditioning and as other adsorbents.

  • Publication number: 20120145042
    Abstract: Disclosed is a process for the calcining and manufacturing of synthetic pozzolan with desirable color properties. Feed material is dried, crushed, and preheated in a drier crusher. The dry, crushed material is collected and fed to a calciner where it is heated to become a synthetic pozzolan. The synthetic pozzolan is then fed to a cooler where it is maintained for a least a portion of the cooling step in a reducing atmosphere.
