恭喜你，收录了，如下 Title: Photochemical oxidation of thiophene by O-2 in an organic two-phase liquid-liquid extraction system Author(s): Zhao D (Zhao, D.), Li F (Li, F.), Han J (Han, J.), Li H (Li, H.) Source: PETROLEUM CHEMISTRY 47 (6): 448-451 NOV 2007 Document Type: Article Language: English Cited References: 8 Times Cited: 0 Abstract: Photochemical oxidation products and the kinetics of thiophene in an n-octane/acetonitrile extraction system using O-2 as an oxidant was studied. The results could be used as a reference for the oxidative desulfurization of gasoline because thiophene is one of the main components containing sulfur in a fluid catalytic cracking (FCC) gasoline. Thiophene dissolved in n-octane was photodecomposed and removed into the water phase at an ambient temperature and atmospheric pressure. A 500-W high-pressure mercury lamp (main wavelength 365 nm, 0.22 kW m(-2)) was used as the light source for irradiation and air was introduced by a gas pump to supply O-2. Thiophene could be photooxidized to SO42- and CO2. The desulfurization yield of thiophene in n-octane is 65.2% for a 5-h photoirradiation under the conditions of air flow at 150 m min(-1) and V(n-octane): V(acetonitrile) = 1 : 1. It can be improved to 96.5% by adding 1.5 g L-1 artificial zeolite, which is an absorbent for O-2. Under such conditions, the photooxidation kinetics of thiophene with O-2 is of the first order with an apparent rate constant of 0.6297 h(-1) and a half time of 1.10 h. The sulfur content can be depressed from 800 to 28 ppm.
