Method of preparing composite biodiesel

Abstract

The aim of the present invention is to overcome the defect of the prior bio-oil ''high-temperature distilling method'' and provide a method for manufacturing a composite bio-oil under normal temperature and pressure. The composite bio-oil is a green, environment-protective and renewable fuel with safe production process and no waste gas. To be specific, the present invention pertains to a fuel manufactured by bio-fat acid and alcohols. The composite bio-diesel contains (weight portion): 30 percent of soil oil fatty acid, 25 percent of castor oil fatty acid, 25 percent of methanol and 20 percent of assistant solvent. The components are all put into a mixing jar for full mixing and added with the raw material assistant solvent; then the mixture including the raw material assistant solvent is fully stirred and mixed. The composite bio-diesel is a high-oxygen and low-carbon fuel with clean combustion and less carbon deposit. The energy consumption rate can be increased by 10 to 15 percent and the oil saving rate is increased by 1.5 to 2.0 percent.

Description

technical field [0001] The present invention relates to a method for producing biodiesel, more specifically, the present invention relates to a method for synthesizing biodiesel from soybean oil fatty acid, castor oil fatty acid, methanol and a compatibilizer. Fuel used in internal combustion engines. Background technique [0002] Since the oil crisis in the 1970s, people have more clearly realized that oil resources are limited, and if they are used without restriction, the depletion of oil resources will be accelerated. Therefore, many countries have been researching raw materials for alternative petroleum fuels. At present, the research and implementation of biodiesel in my country mainly use some bio-oils to adopt the "high-temperature distillation method". This method not only has high production costs, but also has huge potential safety hazards and serious pollution under high temperature and pressure The environment, compared with our country's current oil production ...

At present, the research and implementation of biodiesel in my country mainly use some bio-oils to adopt the method of "high temperature distillation". This method not only has high production costs, but also has huge potential safety hazards and serious pollution under high temperature and pressure The environment, compared with our country's current oil production and resources, compared with our country's population and economic construction, cannot meet the requirements. Therefore, it is very necessary to research and develop a kind of green energy, environmental protection and renewable energy.
