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 micro-emulsion biodiesel and a preparation process thereof. Background technique [0002] As alternative energy sources, biodiesel and micro-emulsion diesel have been concluded in the industry and academia: they are both promising alternative energy sources. However, the high cost of biodiesel requires substantial subsidies from the state; compared with low-cost micro-emulsion biodiesel, not only is the cost low, but the product is almost indistinguishable from standard diesel and biodiesel in appearance, and is a clear, transparent and stable system. Its appearance changed the drawbacks of the early emulsified diesel oil (emulsion) with poor color turbidity and stability, and once became the focus of attention and research of domestic and foreign experts. In recent years, many domestic research institutions have published research results and practical data, w...
