Abstract: The present invention refers to a fuel mixture that contains combustible solid powder and produced by mixing combustible solid powder and liquid fuel. It is in a simple way to make use of renewable biomass materials instead of fossil fuel for driving internal combustion engine to provide powder, in favor of saving fossil fuel resource. And an engine can use the fuel mixture.

Abstract: A stabilized lubricant composition is disclosed that comprises lubricating oil and a mixture of (a) at least one organophosphite compound and (b) at least one aromatic secondary amine or one substituted phenol or mixtures thereof. The compositions have been found to be highly resistant to oxidation under demanding service conditions.

Abstract: The present invention relates to Compositions of fuels for transportation are disclosed, particularly organic compositions which are liquid at ambient conditions. More specifically, it relates to transportation fuels comprising suitable organic distillates, as a predominant component, and limited, but essential, amounts of a component comprising oxygen-containing organic materials, which materials are typically derived from natural petroleum. Beneficially, the oxygen content of these transportation fuels is at least 0.02 percent by weight. Preferably the oxygen content these transportation fuels is in a range from about 0.2 percent to about 10 percent by weight.

Abstract: The fluidity at low temperatures of compositions based on refinery liquid hydrocarbons can be improved by adding, preferably under solution, [l.sub.4 ]-methacyclophanes with substituents, obtained from the condensation reaction of a resorcin with a product containing an aldehyde group, followed by a reaction with halides of organic acids or alkyl halides.
