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.

Nanoparticle additives and lubricant formulations containing the nanoparticle additives

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 H: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.

Nanoparticle catalyst compounds and/or volatile organometallic compounds and method of using the same for biomass gasification

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 COneutral. The energy input to the gasification is correspondingly reduced to reduce costs and the environmental impact associated with the gasification process.
