    摘要： A system is provided for supplying reductants to an emission treatment unit. The system comprises a fuel tank adapted to directly or indirectly supply a first premixed fuel stream and a second premixed fuel stream, wherein each fuel stream comprises a primary fuel component and an oxygenate reductant component. An engine is in fluid communication with the fuel tank, wherein the engine is configured to receive the first premixed fuel stream and create an exhaust stream. The system further includes an emission treatment unit to treat the exhaust stream. A separation unit is configured to receive the second premixed fuel stream, separate the second premixed fuel stream into a first fraction stream and a second fraction stream, and supply the first fraction stream to the emission treatment unit, wherein the first fraction stream comprises a higher concentration of the oxygenate reductant component than the second fraction stream.

    摘要： The present invention relates to various embodiments of a system and method for separating polymer from a solvent. In one embodiment a system for separating polymer from a solvent comprises an extrusion apparatus includes a hollow member having a first end portion, a second end portion, and a feed port between the first end portion and the second end portion. The extrusion apparatus includes a back flash vent port disposed upstream of the feed port and a forward flash vent port disposed downstream of the feed port. The extrusion apparatus further includes a vent insert located at the forward flash vent port, a screw disposed inside the hollow member, and an internal superheating section disposed between the feed port and the downstream vent opening of the hollow member such that the length of the internal superheating section is greater than about four times the diameter, 4D, of the hollow member.

    摘要： A method for preparing a polyimide includes introducing a mixture of an oligomer and a solvent to an extruder, removing solvent via at least one extruder vent, and melt kneading the oligomer to form a polyimide. The polyimide has a low residual solvent content. The method is faster than solution polymerization of polyimides, and it avoids the stoichiometric inaccuracies associated with reactive extrusion processes that use monomers as starting materials.

    摘要： Compatible polyphenylene ether-polyamide blends are prepared without the need for compatibilizing compounds such as citric acid or maleic anhydride. The preparation method includes melt blending of the constituents, with other materials such as impact modifiers and fillers optionally being present, at an apparatus temperature maintained no lower than about 295° C. and a pressure maintained below about 200 torr. Blending is preferably by extrusion, with filler and optionally a portion of the polyamide being introduced downstream.
