    摘要: A system comprises a fuel system for delivering fuel to an engine for combustion and a reductant storage system for delivering reductant to the exhaust stream for an SCR catalyst for NOx reduction. The fuel system further comprises a water separator for separating water-based fluid from fuel in the fuel tank, and a separation reservoir to collect the separated water-based fluid. Based on readings of a water-in-fuel sensor positioned within the reservoir, a type of degradation (e.g., water build-up, high-water-content fuel, mis-filling of the reductant, etc.) may be determined and indicated.

    摘要: Disclosed herein is an improved gas phase process for the selective epoxidation of non-allylic olefins wherein the epoxidation is carried out in the presence of one or more volatile, nitrogen-containing, basic compounds. The presence of a nitrogen-containing basic compound in the olefin-containing reaction gas or vapor suppresses the formation of an organic resinous material which coats the catalyst, thereby decreasing catalyst activity and life and also increases substantially the activity of the epoxidation catalyst. The disclosed process is particularly useful for the continuous manufacture of 3,4-epoxy-1-butene from 1,3-butadiene.

    摘要: The present invention is directed to a process for the selective epoxidation of non-allylic olefins. The process includes the step of contacting a gas mixture comprising a non-allylic olefin, oxygen, and a fluorinated hydrocarbon with a silver epoxidation catalyst at conditions effective to epoxidize the non-allylic olefin. The fluorinated hydrocarbon has a C--F bond dissociation energy of 110 kcal/mole or greater, and sufficiently non-acidic C--H bonds, if present, so as to avoid abstraction of HF from the fluorinated hydrocarbon under reaction conditions.

    摘要: This invention relates to a process for removing sterols and phosphorous compounds from naturally occurring lipid mixtures. The process involves hydrolyzing a naturally occurring lipid mixture containing phospholipids, triglycerides, and sterols to form a two-phase product containing a fatty acid phase comprised of free fatty acids and sterols, and an aqueous phase comprised of water, glycerol, and glycerol phosphoric acid esters. The aqueous phase is separated from the fatty acid phase and the crude fatty acid phase is heated to convert the free sterols to fatty acid sterol esters. The free fatty acids are distilled from the fatty acid sterol esters to yield purified fatty acids which are free of cholesterol and other sterols, and phosphorous compounds.
