Abstract

The invention relates to a microemulsified biodiesel and a preparation technique thereof. The microemulsified biodiesel is prepared from diesel, water, microemulsifier, solubilizer, assistant and catalytic combustion improver in certain parts by weight. The invention enhances the combustion efficiency and utilization efficiency, and has the advantages of low pollutant discharge amount. The invention has the following comprehensive effects: the non-renewable mineral energy is substituted by biomass energy, thereby saving the non-renewable mineral energy; and the invention also has the advantages of energy saving, emission reduction and low production cost.

Description

technical field [0001] The invention relates to a diesel oil and a preparation process thereof, in particular to a microemulsion biodiesel and a preparation process thereof. Background technique [0002] As alternative energy sources, biodiesel and microemulsion diesel have already been concluded in the industry and academic circles: both are promising alternative energy sources. However, the cost of biodiesel is high and requires substantial subsidies from the state. Compared with the low-cost microemulsion biodiesel, it is not only low in cost, but also has almost no difference in appearance from standard diesel and biodiesel, and is a clear, transparent and stable system. Its appearance has changed the drawbacks of early emulsified diesel oil (emulsion) turbidity and poor stability, and once became a focus of attention and research by experts at home and abroad. In recent years, a number of domestic research institutions have published research results and practical data...
