吸附脱除噻吩类硫化物机理的研究进展

Advances in Adsorptive Desulfurization Mechanism for Thiophene-Type Sulfide

针对反应型和非反应型吸附脱硫吸附剂,从实验研究和理论计算两方面,综述了噻吩类硫化物在金属、金属氧化物、分子筛等典型吸附剂表面的吸附原理、作用方式以及现阶段吸附脱硫机理的研究进展,指出虽然目前对吸附脱硫机理的研究仍未达成共识,但是计算研究已成为实验研究的有力辅助工具,为进一步探明吸附脱硫机理提供了有效途径。吸附脱硫机理是吸附剂优化的理论依托,对于指导高效、优化的吸附剂开发具有重要意义。

From both the experimentation and the theoretical calculation,adsorptive principle,action mode and desulfurization mechanism for adsorption of thiophene-type sulfide on typical reactive or non-reactive adsorbents,namely metals,metal oxides and zeolites,were introduced.Though consensus on the adsorptive desulfurization mechanism has not been achieved by now,the theoretical calculation is a powerful assistant for the experimentation.The desulfurization mechanism is the theoretical basis for the adsorbent optimization.
