  • Patent number: 10507453
    Abstract: A nanoclay based solid sorbent is provided having a nanoclay with at least one surface, and at least one amine containing compound wherein the amine containing compound is attached to the surface, as well as a method of making it. A method of capturing carbon dioxide gas is disclosed includes passing a gas from an effluent process stream containing carbon dioxide through the nanoclay based solid sorbent and capturing the carbon dioxide gas on the surface and within the nanoclay based solid sorbent. The nanoclay based solid sorbent having the captured carbon dioxide gas is regenerated by undergoing one or more cycles of desorption of the captured carbon dioxide gas from the nanoclay. The regenerated nanoclay based solid sorbent may then be reused.

  • Publication number: 20150157993
    Abstract: An extensional flow mixing system is provided comprising a cell including an inlet for introducing fluid into the cell and an outlet permitting fluid to flow out of the cell, the cell having an interior surface defining a convergent flow path that has an internal cross-sectional area that preferably decreases from the inlet to the outlet so as to define a direction of convergence from the inlet to the outlet, and an insert extending within the cell in the direction of convergence, the insert comprising at least one protuberance which causes the fluid to undergo an extensional episode, wherein the protuberance is spaced from the interior surface by a dimension “?” that is constant or changes gradually in the direction of convergence. Method of providing extensional flow and production of dispersions are disclosed.

  • Patent number: 7939585
    Abstract: Disclosed is a flame-retardant composition comprising (i) 40-66 wt. % alkenyl aromatic resin, (ii) 9-33 wt. % ammonium polyphosphate and (iii) 14-40 wt. % cellulosic material, wherein all weights are based on the total weight of the composition and wherein ammonium polyphosphate and cellulosic material are present in a weight % ratio effective to provide molded articles exhibiting at least V-1 flame rating as determined according to the UL-94 protocol. A process to prepare the composition and articles comprising a composition of the invention and/or made by the process of the invention described herein are also disclosed.

  • Patent number: 7114374
    Abstract: A method for making fluid elasticity measurements using an extensional viscometer (100) is disclosed, where stress is not directly measured but is inferred from an accurate measurement of the change in the rate of flow of a liquid during passage through a vertical capillary (104). The flow rate changes when the liquid jet, also called the liquid filament, leaving a first capillary (104), is stretched by the application of vacuum forces. Steady flow is established almost instantly by using a constant liquid head (102, 118) above the capillary, and the flow rate is determined by timing the interval for liquid to drain between two marks (110, 112) on the liquid reservoir surface. Extensional viscosity can be calculated as a ratio of the tensile stress and stretch rate of the liquid at different axial positions.
