Biomass methanol diesel oil and preparation method thereof

Abstract

The invention discloses biomass methanol diesel oil. The biomass methanol diesel oil comprises the following components by weight: 100 parts of diesel oil, 40-60 parts of fatty acid methyl ester, 15-40 parts of methanol, and 2-20 parts of composite cosolvent. The biomass methanol diesel oil comprises the following steps: adding 100 parts by weight of diesel oil in a reactor with a stirring apparatus, a heating device, a thermometer and a constant pressure funnel, at 25-500 DEG C, adding 2-20 parts by weight of composite cosolvent, stirring the solution uniformly, gradually adding 40-60 parts by weight of fatty acid methyl ester and 15-40 parts of methanol based in the constant pressure funnel, stirring the mixture uniformly to form the homogeneous biomass methanol diesel oil which is thermodynamically stable. The biomass methanol diesel oil is wide in resource, relatively cheap, high in point of flammability, high in cetane number, and good in water resistance, environmental protection, high safety and renewability, and can be used to directly substitute the common diesel oil in fields.

Description

technical field [0001] The invention relates to a biomass methanol diesel with biomass fatty acid methyl ester, methanol and diesel as raw materials and a preparation method thereof. Background technique [0002] Resource utilization and environmental protection are important issues in the social economy and sustainable development plan in the 21st century. Energy issues will face severe challenges. The development of alternative energy will change the traditional energy structure, replace scarce energy with superior energy, and replace it with renewable energy. The idea of ​​petrochemical energy and gradually increasing the proportion of alternative energy in the energy structure is the strategic policy for the long-term development of our country in the future. [0003] With the improvement of people's production and living standards, the amount of fuel used as power (such as automobiles, fuel generators, internal combustion engines, etc.) has increased rapidly, and gasoli...

AI Technical Summary

Problems solved by technology

[0007] The present invention aims at problems such as low cetane number, low flash point, low calorific value, poor lubricity and corrosion to equipment when pure methanol is used as a power fuel, and the technical process of preparing biodiesel from animal and vegetable oil is cumbersome and the cost is relatively high. Advanced issues, comprehensive raw material sources, environmental protection characteristics, combustion characteristics and other factors, using relatively abundant methanol, animal and vegetable oils, and diesel as raw materials, prepared a new type of biomass methanol that is relatively cheap, environmentally friendly and partially renewable diesel fuel
