摘要:
A diesel fuel lubricant as a replacement for sulfur lubrication in Ultra-Low and Low Sulfur Diesel fuels, the process for producing said lubricant, and the method of using said lubricant. This lubricant comprises alpha-olefins; low odor aromatic solvents; and at least one a base oil selected from the base oil group consisting of hydroisomerized high base oils and HT Severe Hydro-cracked Base Oils; as well as other ingredients. Also disclosed is a method for producing this lubricant.
摘要:
A more complete combustion and a decrease in particulate emissions in the burning of a heavy fuel oil in an industrial boiler or similar combustion device is obtained by first heating the oil to a temperature sufficient to significantly lower its viscosity and continuously mixing a fuel additive containing a solution of a high molecular weight, substantially linear, viscoelastic polymer to the heated oil flowing to the combustion device by mechanically stirring the oil and additive at conditions that do not cause degradation of the viscoelastic polymer through rupture and breakage of polymer molecules.
摘要:
Haze may be removed from a biofuel or biofuel intermediate by using a clarifier. The clarifier includes copolymer prepared using a formulation comprising an alpha olefin and maleic anhydride. The clarifier may also be used with admixtures of biofuels, biofuel intermediates, or biofuel feedstocks with conventional hydrocarbons.
摘要:
The present invention relates to a catalytic process for making isooctenes using a reactant comprising isobutanol and water. The isooctenes so produced are useful for the production of fuel additives.
摘要:
A process for inhibiting the deposition or precipitation of wax in a hydrocarbon fluid such as, for example, a crude oil, and for operating a pipeline is disclosed. The process comprises combining an effective amount of a polymer with the hydrocarbon fluid wherein the polymer comprises random repeat unit of butadiene. Also provided is a composition which comprises a hydrocarbon fluid and a random copolymer which comprises repeat units of styrene and butadiene.
摘要:
AB and ABA block copolymers of acrylics and acrylic amines are useful as oil additives to diminish sediment and color formation. The copolymers are preferably formed by group transfer polymerization.
摘要:
Disclosed herein are embodiments of a method for making jet fuel blendstocks that comprise partially hydrogenated carbocyclic compounds and which can be used to replace aromatic-containing fuels and that exhibit suitable seal swell properties. The disclosed method embodiments utilize catalysts and reaction conditions that facilitate partially hydrogenating carbocyclic compounds present in mixtures obtained from renewable sources, such as bio-based fermentation products. The reaction product mixtures obtained from the disclosed method can be blended with blendstocks to provide fuels that avoid soot formation caused by aromatic-containing fuels and that exhibit seal swelling that meet requirements in aviation systems.
