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.
