特征化学反应增强的吸附法燃油深度脱硫
Deep desulfurization of transportation fuels enhanced by characteristic reaction occurring in mesoporous adsorbent
摘要
Abstract
Commercial gasoline contains several hundreds mg/L sulfur and diesel contains 1000-2000 mg/L sulfur in China, though the fuels have been treated by hydrodesulfurizafion. The high level of sulfur content in fuels makes vehicles emission the major pollution source of urban areas. Considering the sulfur compounds are mainly thiophene and its derivatives after hydrodesulfurizafion, we made a test, in which a characteristic reaction of thiophenic compounds with formaldehyde under catalysis of strong acid occurred in mesoporous adsorbents, and the adsorption of this kind of sulfur compounds was considerably enhanced. Coupled with an oxidation/adsorption treatment, the total sulfur content of commercial fuels dropped to below 15 mg/L.关键词
