  • Patent number: 10745513
    Abstract: A renewable chemical composition is disclosed for use in a variety of industrial applications. The renewable chemical composition may be reacted with an isocyanate to produce a polyurethane material. The renewable chemical composition has aromatic groups. The suitability of this material for use in a variety of applications can be adjusted by modifying the acid number, the Hydroxyl number, the viscosity, the glass transition temperature, the % solids, the softening point, and other properties. The chemical reactivity and properties can be modified based on processing conditions and temperature as well as the source of renewable raw material. The lignin used in these formulations may be from pulp and paper processing such as semi-mechanical processing, soda processing, kraft processing, or biomass processing, or a by-product of ethanol production. The novel biobased polyurethane formulations range in firmness from flexible to semi-rigid to rigid and are useful in large volume polyurethane applications.

  • Patent number: 7932203
    Abstract: A method for producing an oil-binding agent of granular open-porous structure with a silicate ceramic matrix by using recovered paper material and clay. The method is characterized in that, in each case based on the entire raw material, 35 to 60 wt.-% sewage sludge with a water content of between 70 and 85 wt.-%, 25 to 55 wt.-% recovered paper material with a water content of between 35 and 55 wt.-%, 10 to 25 wt.-% clay and optionally 1 to 3 wt.-% zeolite, 1 to 2 wt.-% quicklime and/or up to 3 wt. % fly ash are mixed to a homogeneous mixture. The raw material thus obtained is subsequently processed in order to form particles having an average diameter of 4 to 6 mm. The particles are then dried and subsequently burnt at 950 to 1050° C. The oil-binding agents produced according to said method have a bulk density of between 0.4 and 0.75 kg/1 and a oil-binding capability of 0.7 to 1.0 1 oil per oil-binder.

  • Publication number: 20100006003
    Abstract: The invention relates to a coating, adhesive, and impregnating substance (“Punic Milk”), particularly as a construction and restoration material, comprising a so-called “Punic Wax,” having at least beeswax, potash (K2CO3), and water (H2O), and optionally honey/sugar, and optionally borax casein, wherein the coating, adhesive, and impregnating substance further comprises sodium silicate (Na2SiO2). This results in the advantage that the known “Punic Wax” is provided with relatively high adhesion properties by the addition of sodium silicate (Na2SiO2) and in addition becomes fire-resistant to non-flammable, which can be further amplified by means of the optional addition of honey/sugar and borax casein.

  • Patent number: 7083703
    Abstract: A filler comprising cellulose or lignocellulose fibrils on which light-scattering material particles have been deposited, and a process for the manufacture thereof. In the filler according to the invention, an alkyl derivative of cellulose, such as CMC, has been sorbed to the fibrils. Such a filler can be prepared from a source material containing cellulose or lignocellulose fibrils by first forming a fibril suspension, into which there are fed source materials forming an inorganic or organic salt that, when precipitating, forms a light-scattering pigment. The filler according to the invention has very good strength properties; in particular, good bond strength is achieved by means of it. The concentration of mineral pigment in paper can be increased and, furthermore, the grammage of paper can be lowered without the other important properties of the paper deteriorating.

  • Patent number: 6379446
    Abstract: Compositions and methods in which dry-committed fibers are substantially homogeneously dispersed throughout a fibrous composition. The fibrous composition is characterized as having sufficient yield stress and viscosity such that the shearing forces from the mixing apparatus are effectively transferred down to the fiber level. This is accomplished by means of an appropriate thickening agent, e.g, gelatinized starch. The dry-committed fibers are exemplified by flash dry fibers or fibrous sheets that have been cut or torn into fragments less than 2 cm across. Providing fibers that have been dry-committed greatly reduces the time that it takes to obtain substantially homogeneous dispersion of the fibers throughout the fibrous composition. This, in turn, reduces the risk of mixture spoilage and mechanical or chemical damage to the solid components within the fibrous composition.
