A kind of biomass pyrolysis liquid fuel engine oil composition

Abstract

The invention discloses a biomass pyrolysis liquid fuel engine oil composition. Oil soluble polyether and castor-based sebacic acid polyethylene glycol ester are adopted as base oil, and multiple compound additives are compounded. Multiple compound additives include an antirust agent, an antioxidant preservative, an antifoaming agent, a viscosity index improver, a metal passivator, a clearing agent, a dispersing agent, an antioxidant and a reinforcing agent. The biomass pyrolysis liquid fuel engine oil composition has good clearing and dispersing effects, viscosity-temperature characteristic, base number retainability and acid neutralization capacity, can inhibit generation of polar materials such as oil sludge, can be used for reducing generation of sediments in a piston ring and a bearing bush, has good stability of resistance to high temperature oxidation, resistance to corrosion of halogen family compounds, nitrification resistance, wear resistance, shear resistance and antifriction and antiseptic properties and also has good low temperature startability, low ash content, less carbon deposit and no corrosion or rusting on moving parts.

Description

technical field [0001] The invention belongs to the field of internal combustion engine lubricants, in particular to a biomass pyrolysis liquid fuel engine oil composition. Background technique [0002] Biomass pyrolysis refers to the thermal conversion process of biomass under anaerobic or anoxic conditions. Products include: non-condensable gas, coke, and liquid three categories. The resulting liquid is called "bio-oil". The distribution of biomass pyrolysis products has a great relationship with the material itself and the reaction conditions. At moderate temperature (500-600°C), high heating rate and extremely short residence time, the main product is bio-oil. The efficiency of rapid cracking of biomass into bio-oil can be close to 60%, and its main components are compounds composed of carbon, hydrogen, oxygen and other elements. Usually a mixture of acids, aldehydes, alcohols, esters, ketones, ethers, phenols, o-cresols, syringyl alcohols, furans, lignin-derived sub...

Problems solved by technology

In addition, bio-oil is difficult to compress and ignite in diesel engines, and direct use will cause severe wear and carbon deposition in the injection system, and there are still certain technical difficulties
