燃料油选择性吸附脱硫研究进展

Progress on Selective Adsorption Desulfurization for Fuel Oil

依据燃料油中硫化物与吸附剂表面活性点相互作用的类型,综述了π络合吸附、S—M配位吸附、酸性位吸附和多活性位吸附等选择性吸附脱硫方式的研究进展。认为通过结合多种选择性吸附原理,制备具有多种活性位的吸附剂,达到深度脱硫过程中高选择性和高吸附容量的目的,是燃料油深度脱硫吸附剂研究和开发的主要方向。

According to the type of interaction sorbents, the latest progress of several selective between sulfur compounds in fuel oil and surface active site of adsorption desulfurization processes was reviewed. These interactions included π complexation, direct sulfur-adsorbent（S-M） interaction, acid site adsorption, and multi- active sites synergetic adsorption. The multi-active sites sorbents with high selectivity and high absorption ca- pacity could be obtained by combining several adsorption mechanisms. Therefore, the multi -active site sor- bents will become an important study area for selective adsorption desulfurization of fuel oil.
