摘　　要：高品质燃油在精制工艺中需要深度脱硫,主要是脱除燃油所含噻吩类化合物的硫。为探索燃油深度脱硫的催化剂,采用一锅合成法制备出水油双亲的AEO-7基取代酞菁钴,用于催化脱除硫化钠和噻吩中的硫,并与三种水溶性磺酸氨基取代酞菁钴类脱硫催化剂相比较,根据反应体系耗氧量动力学判断它们的催化脱硫性能。结果发现,在催化脱除硫化钠硫体系中,1min后,AEO-7取代酞菁钴催化反应体系耗氧量仅为最优水溶性脱硫催化剂的1/12。然而,在异辛烷中对噻吩脱硫时,30 min后,AEO-7取代酞菁钴催化体系耗氧量大约是水溶性酞菁催化体系的10倍。可见,AEO-7酞菁钴在燃油深度脱硫工艺中有应用潜力。High quality fuel requires deep desulfurization in exquisite processes,mainly to remove the sulfur of thiophene compounds contained in the fuel.In order to explore catalysts for deep desulfurization of fuel,a one-pot synthesis method was used to prepare AEO-7 substituted cobalt phthalocyanine,which is amphiphilic to water and oil,for catalytic removal of sulfur from sodium sulfide and thiophene.And its catalytic desulfurization performance was compared with three water-soluble sulfonic acid amino substituted cobalt phthalocyanine desulfurization catalysts,based on the oxygen consumption kinetics of the reaction system.It was found that in the catalytic removal of sulfur from sodium sulfide solution,after 1 minute,the oxygen consumption of the AEO-7 substituted cobalt phthalocyanine catalytic reaction system was only 1/12 of the optimal water-soluble desulfurization catalyst.However,after 30 minutes of desulfurization of thiophene in isooctane,the oxygen consumption of AEO-7 substituted cobalt phthalocyanine catalytic system was about 10 times as high as that of water-soluble phthalocyanine catalytic systems.It can be seen that AEO-7 cobalt phthalocyanine has the potential to be applied in the deep desulfurization process of fuel.
