中文摘要：

A new continuous process for preparing methanol-diesel emulsified fuel with an Impinging Stream-Rotating Packed Bed is proposed. The droplet size of dispersed phase(methanol) of the emulsified fuel has a significant effect on the combustion of methanol-diesel emulsified fuel. In this paper, the methanol-diesel emulsified fuel uses diesel as the continuous phase and methanol as the dispersed phase. The Sauter mean diameter of the dispersed phase of methanol-diesel emulsified fuel was characterized with microphotography and arithmetic method. The experimental result showed that the Sauter mean diameter of the dispersed phase, which was decreased with the augmentation of the high gravity factor, liquid flow rate and emulsifier dosage, was inversely proportional to the methanol content. The Sauter mean diameter of the dispersed phase can be controlled and adjusted in the range of 12—40 μm through the change of operating conditions. The correlative expressions of the Sauter mean diameter of emulsified fuel were obtained and the calculated values agreed well with the experimental values.

A new continuous process for preparing methanol-diesel emulsified fuel with an Impinging Stream-Rotating Packed Bed is proposed. The droplet size of dispersed phase （methanol） of the emulsified fuel has a significant effect on the combustion of methanol-diesel emulsified fuel. In this paper, the methanol-diesel emulsified fuel uses diesel as the continuousphase and methanol as the dispersed phase. The Sauter mean diameter of the dispersed phase of methanol-diesel emulsifiedfuel was characterized with microphotography and arithmetic method. The experimental result showed that the Sautermean diameter of the dispersed phase, which was decreased with the augmentation of the high gravity factor, liquid flowrate and emulsifier dosage, was inversely proportional to the methanol content. The Sauter mean diameter of the dispersedphase can be controlled and adjusted in the range of 12-40 μm through the change of operating conditions. The correlativeexpressions of the Sauter mean diameter of emulsified fuel were obtained and the calculated values agreed well with the experimental values.
