Abstract: Polyoxymethylene dimethyl ethers(PODE) made from non-petroleum-based substitude fuel is a new kind of green and environment-friendly diesel fuel additive,which has excellent performance and great application potential because of its high cetane number,high oxygen content and non-intermiscibility gap between diesel. It can improve the diesel fuel's cetane number and combustibility while reduce the emissions of pollutant. This work presents an overview of PODE. First,the physico-chemical characteristics and some performance indexes for diesel fuel of PODE_n has been described in detail. Then the recent research progress of synthesis technology and mechanism of chain propagation for synthesis reaction was also summarized. Using ionic liquid thin film catalysis as the possible industrialization route for PODE was proposed. The research progress of PODE_n as diesel addictive and its new applications of being new component in fuel and new type of green solvent oil was also presented. Finally the trend and key tasks of future research work was pointed out. The proper degree of polymerization and addictive amount of PODE should be determined,and the combustion and power performance of diesel fuel blended with PODE should be checked by lots of experiments. The production standard should be also established.

Key words: polyoxymethylene dimethyl ethers, diesel fuel additives, combustion and emission
