The Study on the application of Low Polymerization degree PODE2.

Polyoxymethylene dimethyl ethers (PODEn) are a kind of excellent diesel blending components. Due to the low flash point of PODE2, it is not appropriate to be used as diesel blending component, so in this paper, the application of PODE2 have been studied. It seems that PODE2 is a kind of excellent green rubber solvent oil without sulfur and aromatic. Moreover, the application of PODE2 as gasoline blending component is investigated and it is found that the Research Octane Number(RON) of gasoline product and the RON of four different gasoline components(including hydrofining gasoline, hydrocracking light naphtha, catalytic reforming gasoline and mixed gasoline with 80vol% hydrofining gasoline and 20vol% catalytic reforming gasoline) is all slightly decreased to some extent respectively, which indicates that there is no apparently synergistic effect between PODE2 and the gasoline components, but PODE2 can effectively reduce the sulfur content, olefin content, aromatic content and can suppress the vapor pressure of gasoline.
