The invention discloses a catalyst removal method of liquid rubber containing a lithium catalyst and a preparation method of the liquid rubber. The method comprises the following steps: (1) carrying out first mixing on liquid rubber containing a lithium catalyst, water and a demulsifier composition, and then carrying out first standing layering to obtain a first oil phase; wherein the demulsifier composition comprises a component A and a component B, and the component A is selected from one or more of inorganic salts; the component B is selected from one or more of alkylated amine, alkaryl sulfonate, alkoxylated phenolic resin, glycol esters, fatty acid ester and oxyalkylated polyol; (2) carrying out second mixing on the first oil phase and water; and then carrying out second standing layering to obtain a second oil phase, namely the liquid rubber after the catalyst is removed. According to the method, oil-water layering can be realized in a short time, the effect of rapidly removing the catalyst is achieved, and the residual quantity of metal ions in the product is low.

The invention relates to the technical field of lubricating oil, in particular to natural gas engine oil and a preparation method thereof. The invention relates to natural gas engine oil which is prepared from the following components in percentage by weight: 70%-80% of hydrogenated base oil, 10.0%-15.0% of a complexing agent and 5.0%-10.0% of an additive, wherein the complexing agent comprises an alkylphenol antioxidant, an alkaryl sulfonate detergent, zinc alkyl dithiophosphate, a borate antioxidant and an arylamine anti-nitration agent; and the additive comprises 1.5%-3.0% of MoDTC (Molybdenum Diethylene Terephthalate).

The invention relates to a nano imbibition agent for enhancing shale oil imbibition and displacement dual-interface regulation and a preparation method. The nano imbibition agent comprises the following components: long-chain alkyl aryl sulfonate, a co-surfactant branched fatty alcohol polyoxyethylene polyoxypropylene block polyether sulfonate anionic-nonionic surfactant, mineral oil and water, wherein the long-chain alkyl aryl sulfonate accounts for 30-50% of the total mass of the system, the cosurfactant branched-chain fatty alcohol polyoxyethylene polyoxypropylene block polyether sulfonate anion-nonionic surfactant accounts for 10-30% of the total mass of the system, the mineral oil accounts for 5-20% of the total mass of the system, and the balance is water. The shale oil imbibition and replacement mechanism is disclosed, the imbibition agent with the imbibition enhancing function is designed according to the pore distribution characteristics and wettability of the shale reservoir, the imbibition and replacement effect of the imbibition agent applied to the shale oil reservoir is evaluated, effective economic development of shale oil in China is promoted, and therefore the shale oil imbibition and replacement method has wide application prospects.
