A composition is provided for a non-aqueous foaming aerosol cleaner or lubricant. Foam builders, especially silicone glycol copolymers, are used to generate high density foam of the solvent-based formula. A cleaning product variant may be introduced via an air intake route for loosening deposits in an internal combustion engine. The high foam aerosol product dispenses easily without causing engine stalling. A process of lubricating a target substrate is also provided.

A method minimizes power loss in a direct injection diesel engine by adding a copolymer to a diesel fuel composition. The copolymer contains, in a copolymerized form, (A) maleic anhydride, (B) an α-olefin having from 12 to 30 carbon atoms, (C) optionally an additional aliphatic or cycloaliphatic olefin which has at least 4 carbon atoms and is different from monomer (B), and (D) optionally an additional copolymerizable monomer other than monomers (A), (B) and (C). Monomer (D) can be a vinyl ester, a vinyl ether, a (meth)acrylic ester of an alcohol having at least 5 carbon atoms, an allyl alcohol or an ester thereof, a N-vinyl compound, an ethylenically unsaturated aromatic, an α,β-ethylenically unsaturated nitrile, a (meth)acrylamide, or an allylamine. Anhydride functionalities present in the copolymer are partly reacted with at least one compound (E) comprising an alcohol group and/or an amino group, and the anhydride functionalities present are hydrolyzed.

Provided are automated systems and methods for measuring the physical properties of fuels in large storage tanks, and for blending butane into the fuels, including chemometric methods for controlling physical properties selected from volatility, butane content, and density of the fuel during the blending process.

The invention relates to a fuel composition based on a diesel fraction, having a sulphur content of less than 10 mg/kg with the boiling range of 180-360° C., characterized in that said fuel composition contains organic peroxides as ignition promoters, which are selected from the group: di-tert-butyl peroxide, 1,1-di-(tert-butylperoxy)cyclohexane, dicumyl peroxide, tert-butyl cumyl peroxide, isobutyl cumyl peroxide, n-butyl cumyl peroxide, isopropyl cumyl peroxide, ethyl cumyl peroxide and methyl cumyl peroxide, and contains an anti-wear additive based on carboxylic acids having the following ratio of components, wt %: 0.01-0.5 organic peroxide, 0.005-0.1 anti-wear additive, and up to 100 being the diesel fraction. The proposed diesel fuel composition allows producing diesel fuel which meets quality performance requirements.

Systems and methods to provide renewable transportation fuels for internal combustion engines by converting renewable feedstocks into two or more intermediate hydrocarbon blend stocks and blending at least two of the two or more intermediate hydrocarbon blend stocks to produce the renewable transportation fuel. Methods and/or processes may include selecting sugar from a sugar source and introducing the sugar into one or more reactors. The sugar may be converted into an intermediate renewable hydrocarbon blend stock and sent to a separation unit to separate out an intermediate renewable gasoline unit. The process may include selecting and converting a lipid from a lipid source into a renewable diesel product. The renewable diesel product may be sent to a second separation unit to separate out renewable diesel and a low-grade naphtha. The low-grade naphtha and intermediate renewable gasoline may be blended to define a finished renewable gasoline.

There is provided a method for blending coals for coke production, in which the strength of coke produced from a coal blend serving as a raw material is estimated using a physical property that has not been taken into consideration in the past as an index, so that the method is capable of suppressing an increase in the raw material cost of the coal blend and increasing the strength of coal. Two or more coal brands are blended together to provide a coal blend for coke production. When the two or more coal brands are blended together, the coal brands and the blending ratio of the coal brands are determined using the surface tension of each of the coal brands subjected to heat treatment, the surface tension serving as a control index.
