摘要:

针对吸附脱硫的分子扩散和表面吸附两个过程。从分子尺寸选择、酸性位点吸附以及配位作用等方面综述了现有的吸附脱硫机理，介绍了各个机理指导下的液相吸附脱硫技术。指明了吸附脱硫机理的研究对开发高效燃油深度脱硫吸附剂和吸附脱硫新技术的指导意义。

Abstract:

The existing mechanisms of adsorptive desulfurization was reviewed from a view of the molecular diffusion and surface adsorption processes in several aspects: molecule size selection, acidic sites effect and the complexation between sorbents and sulfuride
