Description

The lubricant compositions of including gas to liquid base oils

Technical field

The present invention relates to lubricant compositions, particularly relate to and contain gas to the lubricant of liquid base oils as unbalanced base stock.

Background technology

Because to continuing to increase of gasoline and petroleum liquid product demand, the petroleum liquid reserves continue to descend.Owing to, need more these reserves to be used to produce gasoline and fuel oil product, and these reserves still less can be directly used in the production lubricant base stock to continuing to increase of energy demand.For example, now invented C ₁-C ₃Alkane is converted into the method for petroleum liquid oil base stock.

Yet various sources of the gas can be used for the component that can be converted into the petroleum liquid product is provided, and include but not limited to refuse embedded gas (land fill gas), oil drilling operation tail gas, methane, Sweet natural gas etc.In view of the new source of these lubricant base stock has the characteristic that is different from conventional oil base stock, need to join compositions of additives in this oil base stock so that the lubricant that is fit to application-specific to be provided.

For foregoing, exemplary embodiment of the present invention provides a kind of lubricant compositions, the purposes of this lubricant compositions, and the method for using this lubricant compositions lubrication fittings.This lubricant compositions comprises first base oil component, and it comprises first base oil that is derived from source of the gas.Described first base oil has the viscosity index greater than about 115, contains the sulphur that is less than about 0.3 weight %, and the branched paraffin that it is characterized in that having the about 100 weight % of about 95-.Second base oil that is derived from petroleum liquid source can be chosen wantonly and comprise first base oil, and wherein the base oil component of this lubricant compositions comprises first base oil of the about 100 weight % of about 5-.This lubricant compositions also comprises about 30 weight % of about 1-or higher solubilizing agent, described solubilizing agent select oneself diester, polyol ester, alkylated naphthalene, alkylation sulfone, naphthenic base crude, aromatic base crude oil, alkylated benzenes and above-mentioned two or more combination.In first base oil, also there is binder component.

Be different from traditional lubrication agent composition, composition described herein comprises first base oil component that is derived from source of the gas.This base oil can be reallocated liquid hydrocarbon source to produce fuel such as gasoline, oil fuel and rocket engine fuel etc.Source of the gas is converted into the liquid lubricant product also may reduces the byproduct that can not use as fuel and the burning of tail gas.These base oil typical earth surfaces reveal very high viscosity index, fabulous oxidation-resistance and good pour point.Other benefit of lubricant compositions described herein can be known from the detailed description of exemplary embodiment of the present invention.

Summary of the invention

Use with its conventional sense at this employed term " hydrocarbyl substituent " or " alkyl ", it is that those skilled in the art are known.Specifically, it is meant carbon atom with the rest part that is directly connected in molecule and the group with main hydrocarbon character.The example of alkyl comprises:
