查询词典 oxidization

In supersonic condition Ce~(4+) may oxidize sulfur compound such as benzothiophene mainly in diesel fuel into sulfonea for the first time. By choosing proper solvent to extract sulfonea, thus sulfur content in diesel fuel is reduced from 554mg/L to 25mg/L, up to 95.5 % desulfurization ratio and the sulfur content of diesel oil by oxidization meet to the quality standard of diesel oil in World Fuel standard III.
