摘要： Provided herein are compositions of matter useful in de-inking secondary fibers. A composition according to the invention includes an aqueous solution of an anionic form of a styrene-methacrylic acid copolymer. When a surfactant is used in combination with the copolymers herein described in a de-inking operation, a synergy is observed in that the combination of copolymer and surfactant combination together yield a recycled fiber product having higher brightness level and a lower effective residual ink concentration than recycled fibers produced using either the copolymer or surfactant alone in the same operation.

摘要： Methods of treating hydrocarbon fluids to reduce the apparent viscosity of hydrocarbon fluids encountered in petroleum operations and reducing deposits within a well annulus or a pipeline are disclosed. The method comprises contacting such fluids with a hydrophobically modified polysaccharide to create water external emulsions. The disclosed hydrophobically modified polysaccharides have been demonstrated to reduce interfacial tension to below 65 mN/m and thereby improve the transportability of inherently viscous hydrocarbon fluids, such as heavy crude oils.
