Poly(oxymethylene) dimethyl ethers as components of tailored diesel fuel: Properties, synthesis and purification concepts

Performance, combustion and emission characteristics of a diesel engine fueled with polyoxymethylene dimethyl ethers (PODE3-4)/ diesel blends

“…The main properties of PODEn are listed in Table 1. Among PODEn, PODE 2 does not fulfill the security criterion due to its low flash point [21], and if n is higher than 5, melting points will be too high, and there will be precipitate in diesel/PODEn blend fuel at low temperatures. Therefore, only PODE 3e5 mixtures are ideal diesel fuel additives without compromising ignitability.…”

The study on the application of low polymerization degree PODE2

“…Polyoxymethylene dimethyl ethers (PODEn) as a kind of downstream product of methanol and green oxygenated diesel fuel component has been received wide attention in recent years. It can significantly improve combustion efficiency and reduce soot emission, PM emission and without changing the engine infrastructure with the proportion of 5%-10% in diesel fuel 1 . It was well known that PODE2 component shows low flash point and boiling point, which is not suitably to be used as diesel component.…”

Pyrolysis Characteristic Analysis of Particulate Matter from Diesel Engine Run on Diesel/Polyoxymethylene Dimethyl Ethers Blends Based on Nanostructure and Thermogravimetry

“…As a new type of oxygenated fuel, polyoxymethylene dimethyl ethers (PODE n ) are effective at reducing diesel PM emissions because PODE n have no C-C bonds in their molecular structure, a substantial carbon/hydrogen ratio and high oxygen content with a large cetane number (Burger et al, 2010;Zhao et al, 2011;Zhao et al, 2013;Yang et al, 2015). PODE n can be synthesized through a polymerization reaction using methanol as a raw material, and many crude materials can be used to produce them, including coal and biomass.…”
