摘要
Abstract
A study on the desulfurization of oil by catalytic oxidation in emulsion system with hydrogen peroxide as oxidant has been conducted,where the phosphotungstic acid alkyl betaine was used as a phase transfer catalyst. It investigated the catalytic properties of phosphotungstic acid C14 alky betaine,phosphotungstic acid C16 alky betaine and phosphotungstic acid C18 alky betaine. Influences of the amount of catalyst,reaction time,emulsion mixing speed and n(oxygen)/n(sulfur) on oil desulfurization were also tested. The results indicated that the longer the chain of the alkyl betaine, the better the catalytic effect. The ratio of n(oxygen)/n(sulfur) was 11,the desulfurization rate was up to 91.23%when the amount of catalyst was 0.003(the mass ratio of catalyst and model oil),reaction time was 8 minutes,and the emulsion mixing speed was 2500r/min.关键词
