Patent CA-2793849-A1 (CA)
Inventor: CHENG WEIGUO
IPC: D21H17/63
Filed: 2011-03-18
Abstract: The invention provides a method of producing paper with a higher proportion of mineral filler particles than is otherwise be possible without the expected loss in paper strength by preflocculating the filler particles. The method allows for the use of the greater amount of filler particles by coating at least some of the filler particles with a material that prevents the filler materials form adhering to a strength additive. The strength additive holds the paper fibers together tightly and is not wasted on the filler particles.

Abstract: A multilayer assembly (10) for use in a vegetated eco-roof or wall system includes layers of progressively permeable geomatrix material. Preferred embodiments of the multilayer assembly are composed of a filtration layer (22) of a nonwoven type positioned between a three-dimensional drainage/aeration base layer (24) and a growing media support layer (26). The sizes and structures of the pores of the base layer, openings of the filtration layer, and pores of the growing media support layer cooperate to permit flow of liquid from the growing media support layer through the base layer and form a gas flow gradient throughout the multilayer assembly. The gas flow gradient permits passage of gas from the base layer to the growing media support layer to mitigate moisture accumulation at the base layer.

Abstract: There is provided a dimensionally stable laminated paperboard material having a tear-resistant polymer film core. The tear-resistant paperboard laminate is a multi-layer paperboard laminate with an integral polymer core having a tear resistance a thickness of at least 1 mil and a tear resistance of at least 350 grams of force in machine direction and 400 grams of force in cross direction, as measured by the Elmendorf tear propagation test. Two paperboard substrates are bonded on respective opposite sides of the polymer core, to provide printability, facilitate adherence and prevent frictional resistance. The multi-layer paperboard-polymer- paperboard laminate is particularly useful for child-resistant, senior-friendly and pilfer- proof packaging and may be printed on, hot-stamped, embossed, die-cut and glued using conventional printing and converting techniques. An adhesive laminating process and an extrusion laminating process for manufacturing the laminate are also disclosed.

Inventor: RUSEK JOHN J
IPC: C12N1/20
Filed: 2011-03-03
Abstract: The present invention provides non-petroleum high-octane fuel derived from biomass sources, and a method of producing same. The method of production involves reducing the biomass feedstocks to sugars, fermenting the sugars using microorganisms or mutagens thereof to produce ethanol or acetic acid, converting the acetic acid or ethanol to acetone, and converting the acetone to mesitylene and isopentane, the major components of the renewable engine fuel. Trimerization of acetone can be carried out in the presence of a catalyst containing at least one metal selected from the group consisting of niobium, iron and manganese. The ethanol can be converted to mesitylene in a dehydration reaction in the presence of a catalyst of zinc oxide/calcium oxide, and unreacted ethanol and water separated from mesitylene by distillation. These ethanol-based, biomass-derived fuels are fully renewable, may be formulated to have a wide range of octane values and energy, and may effectively be used to replace 100 LL aviation fuel (known as AvGas), as well as high-octane, rocket, diesel, turbine engine fuels, as well as two-cycle, spark-ignited engine fuels.

Abstract: Renewable oils are converted to aromatics, by contact with a catalytically-active form of gallium, for use in the petrochemical industry and/or for fuel blending components or additives. The renewable oil(s) feature high oxygen content, high H/C mole ratios, and high fatty acid or fatty acid ester content prior to heating and contact with the catalyst. The catalyst may be, for example, a gallium-doped version of one or more zeolite- alumina matrix catalysts with pore sizes having 10 oxygen atoms in the pore mouth, such as ZSM-5, ZSM-11, ZSM-23, MCM-70, SSZ-44, SSZ-58, SSZ-35, and ZSM-22. Aromatics -production from the renewable oils is enhanced at higher gallium-cation levels, with the preferred level being about 1.0 Ga/framework-Al. While various renewable oils, or "bio-oils," may be used, algae oil has exhibited very high BTEX yields over the gallium cation catalyst, under conditions at or near 1 atm and approximately 400 degrees C.
