Abstract
The invention discloses microemulsified biodiesel and a preparation method thereof. The microemulsified biodiesel comprises: by weight, 88 to 92% of biodiesel, 1.0 to 2.0% of an emulsifier EL-12 (castor oil-ethylene oxide condensation product), 1.0 to 2.0% of Span 80 (sorbitan monooleate), and 5 to 10% of water, wherein a use amount ratio of the emulsifier EL-12 to the Span 80 is in a range of 0.9 to 1.1. The preparation method comprises the following steps of uniformly mixing the biodiesel, the emulsifier EL-12 and the Span 80 according to the above ratios, and adding a certain amount of water into the mixture with stirring. The microemulsified biodiesel has wide raw material sources, needs simple preparation processes and has a low cost. After microemulsification, the microemulsified biodiesel has low viscosity, good stability and a high combustion ratio, and can be used widely.
Description
Technical field
The invention belongs to the biofuel processing technique field, the micro-emulsified biological diesel that be specifically related to a kind of homogeneous, stablize, combustion heat value is high.
The invention still further relates to the working method of above-mentioned micro-emulsified biological diesel.
Background technology
Micro-emulsified biological diesel is compared with biofuel, and it is few that burning generates NOx, and the soot emissions amount is little, can realize good environmental protection and energy saving effect.The micro-emulsified biological diesel technology is come out and has been obtained some achievements in decades, but also has some problems simultaneously.Gao Yongjian people such as (CN101348748A) has studied with mineral diesel, animal oil and fat, methyl alcohol, naphthenic acid, OP emulsifying agent, sodium laurylsulfonate and trolamine and has prepared micro-emulsified biological diesel, and its emulsifying agent is formed many, the prescription more complicated.Sun Ping people such as (CN200810234563) has studied the micro-emulsified biological diesel with biofuel, water and the preparation of polyoxyethylene octylphenol ether series compound surfactant, but prolonged preservation, but the consumption of emulsifying agent is up to 10-20% (mass percent).Also there are the shortcoming that prescription is complicated, emulsifier proportion is bigger in domestic other patents such as CN1087556A, CN101250431A etc. at present.The patent of external relevant microemulsion technology (as; U.S. Pat 6997964, US5820640, US20040098905A1, US005743922A etc.) though the emulsifying agent consumption is less and the prescription simple; But these patents mainly are to be diesel oil optimization, and do not have to be directed against specially the emulsification prescription of biofuel.In sum, still there are some defectives in present micro-emulsified biological diesel processing technology: the emulsification prescription is complicated, the emulsification cost is high, though can reach the fuel-economizing purpose, deficiency in economic performance, industrial application value is little.
