Abstract

The present invention provides a biomass base oil prepared from natural fatty alcohol front distillate as a raw material. The invention provides a method for preparing a biomass base oil, which comprises: reacting a natural fatty alcohol front distillate, an alkyl reagent and an alkaline compound under the action of a catalyst to obtain the biomass base oil. The biomass base oil provided by the invention is a natural aliphatic hydrocarbon mixed ether, which has the characteristics of environmental protection, non-toxicity, strong lubrication, no fluorescence, high temperature resistance, salt resistance, calcium resistance and hydrolysis resistance, and is a lubricant with excellent performance. Use base oil. The preparation method of the biomass base oil provided by the invention has high reaction yield, good product quality, simple preparation method, mild conditions, non-toxicity, high efficiency and environmental protection in the preparation process.

Description

technical field [0001] The invention relates to the technical field of base oil, in particular to a biomass base oil and a preparation method thereof. Background technique [0002] Nowadays, with the expansion of the field of petroleum exploration and development, the drilling strata are deepening, the drilling methods are constantly renovated, and the drilling difficulty is also increasing year by year. Deep wells, ultra-deep wells, directional wells, horizontal wells, extended reach The number of wells with special conditions such as long open-hole wells is increasing, and the drilling speed needs to be greatly increased. The use of lubricants is a solution to these complex problems. [0003] There are relatively few types of lubricants currently used in my country's oil and gas drilling industry, and they all have certain limitations. For example, it is not environmentally friendly to use mineral oils such as crude oil and white oil as lubricants; oleate-modified lubrica...
