  • Publication number: 20110088656
    Abstract: A method of operating a combustion ignition engine comprises introducing an amount of a compressibly non-ignitable fuel into the air induction system of a compression ignition engine during the intake stroke of the engine and then injecting an amount of compressibly ignitable fuel (e.g., Diesel fuel) in the cylinder chamber at a crank angle sufficiently advanced during the compression stroke of the compression ignition engine such that the compressibly ignitable fuel and incompressible non-ignitable fuel ignite and combust such that substantially all of the fuel in the cylinder is combusted, where the amount of compressibly non-ignitable fuel introduced into the cylinder has an energy content that is at least about 50% to at most about 99% of the total energy content of the total amount of fuel introduced.

  • Publication number: 20110083955
    Abstract: The present invention provides one-step processes for the production of chlorinated and/or fluorinated propenes. The processes provide good product yield with low, e.g., less than about 20%, or even less than 10%, concentrations of residues/by-products. Advantageously, the processes may be conducted at low temperatures than 500° C. so that energy savings are provided, and/or at higher pressures so that high throughputs may also be realized. The use of catalysts or initiators may provide additional enhancements to conversion rates and selectivity, as may adjustments to the molar ratio of the reactants.

    Abstract: Methods and assemblies for improving the reaction kinetics of, conserving reactants utilized in, and/or producing a more pure reaction product of, liquid-phase reactions that involve volatile reactants and products are provided. The methods and assemblies herein provide for a feed of reaction liquid to two or more absorption zones, wherein the temperature and/or feed rate of the liquid is independently adjusted prior to introduction into at least one of the two or more absorption zones. More particularly, the temperature and feed rate of the liquid as delivered to each absorption zone can be adjusted independently to optimize the absorption of at least a portion of any gaseous reactants and byproducts from the gaseous product stream and/or to optimize reaction zone conditions. Reaction kinetics may thus be improved, or substantially maintained.
