Desulfurization of Simulated Oils by Microwave Chemical Methods

Microwave technology was introduced for the desulfurization of sulfurous crude oil and the influence of microwave processes on removing benzothiophene sulfur and bi-benzothiophene sulfur in simulated oils was studied in this article. The results manifested that the desulfurization efficiencies of BBPV, formylhydroperoxide and peroxyacetic acid for an oil sample (simulated oil 2) containing bi-benzothiophene were better than for the oil sample (simulated oil 1) containing benzothiophene. When dosages of BBPV increased from 0.5% to 4%, the desulfurizing efficiencies of simulated oil 1 and 2 were raised from 19.8% to 53.7%, and 48.0% to 64.2%, respectively. With the increase of temperature, the reaction order desulfurization of the simulated oils by microwave increased, and the rate of the microwave reaction increased. The desulfurizing efficiency increases along with the temperature in the same time.
