Embodiment
Below in conjunction with specific embodiment the present invention is done explanation further, but specific embodiment is not done any qualification to the present invention.
The screening of embodiment 1 emulsifying agent
In view of the influence of emulsifying agent to micro-emulsified biological diesel stability and quality, so present embodiment is optimized and screens emulsifying agent, specifically is divided into following several steps.
One, the result of use of single emulsifying agent
At first study the consumption that forms micro emulsion when single emulsifying agent uses, to confirm the efficient of emulsifying agent.
The emulsifying agent that present embodiment is selected has polyoxyethylene octylphenol ether (OP series), polyoxyethylene nonylphenol (TX series), AEO (AEO series), cetyl trimethylammonium bromide (CTAB), dioctyl sodium sulfosuccinate (AOT), sapn (Span series), tween (Tween series), triethanolamine monooleate ester and fatty acid amide etc.
Experimental technique: after different emulsifiers and solubility promoter (propyl carbinol) mix by mass ratio 1:1; Dropwise add in the biofuel (water oil ratio of this biofuel is 0.90, profit total mass be 10g); Stir while dripping; Till liquid became the clear state, record added the quality of emulsifying agent.

Can find out from table 1:
The relative composite emulsifier of consumption (AOT+AEO-7) was more bigger when composite emulsifier (CTAB+AEO-7) formed micro-emulsified biological diesel, but excellent stability is placed not stratified for a long time; But, CTAB is a quaternary ammonium salt emulsifying agent, is nitrogenous compound, can cause the discharging NO of micro emulsion diesel fuel
XRaise, therefore consider, do not adopt emulsifying agent CTAB from the angle of environmental protection;
Consumption was less when composite emulsifier (AOT+AEO-7) formed micro-emulsified biological diesel, but the microemulsion that forms is unstable, very easily layering; Hence one can see that, and AOT is not suitable for the micro-emulsified biological diesel emulsifying agent;
Other three kinds of composite emulsifiers were all more relatively for consumption when composite emulsifier (AEO-9+AEO-7) formed micro-emulsified biological diesel, and stability is general, placed to occur demixing phenomenon in three days;
Other three kinds of composite emulsifiers were all less relatively for consumption when composite emulsifier (AEO-3+AEO-7) formed micro-emulsified biological diesel, and excellent stability, placed not stratified for a long time.
In sum; Composite emulsifier of the present invention adopts the composite of AEO AEO-3 and AEO AEO-7, because this composite emulsifier can guarantee that the microemulsified of biofuel, microemulsified are effective, good stability, consumption are few, do not contain the discharging that organonitrogen can not cause oxynitride.
In addition; The contriver is also to the composite optimization of carrying out concrete consumption of AEO AEO-3 and AEO AEO-7; Confirm that through experiment contrast back AEO AEO-3: the mass ratio of AEO AEO-7 is 1:2～1:8 in the composite emulsifier of the present invention; Because find according to the research contriver; The mass ratio of AEO AEO-3 and AEO AEO-7 is if be lower than this proportional range; Then its microemulsified effect to biofuel can be poor, and then therefore it take all factors into consideration the also not obviously raising of microemulsified effect of biofuel if be higher than this proportional range; The final selection in the composite emulsifier of the present invention, AEO AEO-3: the mass ratio of AEO AEO-7 is 1:2～1:8.
