  • Patent number: 8741821
    Abstract: A method for reducing a friction coefficient adjacent a lubricated surface, and a lubricant composition for reducing a friction coefficient between lubricated surfaces. The method includes providing an amount of metal-containing dispersed in a fully formulated lubricant composition containing a base oil of lubricating viscosity, wherein the nanoparticles have an average particles size ranging from about 1 to about 10 nanometers. The lubricant composition containing the metal-containing nanoparticles is applied to a surface to be lubricated.

  • Patent number: 8404155
    Abstract: A nanocatalyst, dual catalyst and methods for improving the efficiency and output of a biomass gasification process are provided where the catalysts comprise a volatile organometallic compound(s) and/or a nanoalloy catalyst. By the catalyst and method, a very high biomass gasification conversion efficiency of over 85% can be achieved. The subject nanocatalyst cracks and gasifies lignin, which is generally inert in conventional gasification, at relatively low gasification temperatures. The subject disclosure also provides a means to increase gas yields and lower lignin content in the resulting product relative to conventional gasification. Alternatively, oil production may be increased, if desired. Moreover, the resulting gas may achieve a Fischer-Tropsch reactor favorable H2:CO ratio of about 9:1. The energy input to the gasification is correspondingly reduced to reduce costs and the environmental impact associated with the gasification process.

  • Patent number: 8241599
    Abstract: The present invention relates to a method for improving biomass gasification. By the present invention, volatile organometallics are contacted with a biomass before or during gasification. By this method, the biomass improves gas yields while reducing solid (tar) and liquid yields. In addition, the volatile organometallics interact with lignin in the biomass to produce methanol, which, in turn, results in a stable liquid or oil by-product or otherwise stabilizes the gasification process of the biomass. The presently disclosed method can also lead to increased syngas production and is potentially CO2 neutral. The energy input to the gasification is correspondingly reduced to reduce costs and the environmental impact associated with the gasification process.

  • Publication number: 20110315931
    Abstract: A nanoalloy catalyst, dual catalyst and methods for improving the efficiency and output of a biomass gasification process are provided where the catalysts comprise a volatile organometallic compound(s) and/or a nanoalloy catalyst. The subject nanoalloy catalyst cracks and gasifies lignin, which is generally inert in conventional gasification, at relatively low gasification temperatures. The subject disclosure also provides a means to increase gas yields and lower lignin content in the resulting product relative to conventional gasification. Alternatively, oil production may be increased, if desired. Moreover, the resulting gas may achieve a Fischer-Tropsch reactor favorable H2:CO ratio of up to about 9:1. The energy input to the gasification is correspondingly reduced to reduce costs and the environmental impact associated with the gasification process.
