Abstract

Abstract: Effect of methanol content,different kinds and contents of emulsifying agent and co-emulsifying agent,HLB value,emulsifying time and stirring speed on the stability of methanol-diesel emulsions was investigated under 20 ℃.Experimental results showed that the stability of the emulsion firstly increases and then decreases with the increase of content of blend emulsifying agent and co-emulsifying agent,as well as HLB value and stirring speed.As the extension of emulsifying time,the stability of the emulsion increases firstly and then gradually reached a plateau.The stability of the emulsion decreases with the augment of the methanol content.Based upon the experimental results the suitable operating parameters were identified as:emulsifying time,2 min;stirring speed,5×2 800 r·min^-1;HLB value,4.5;content of both the emulsifying agent and co-emulsifying agent,3% for each;methanol content,15%.Sauter mean diameter of the emulsion particles was measured as 13 μm.

Key words: methanol-diesel emulsion, stability, emulsification efficiency
