FCC催化汽油吸附脱硫技术的研究进展

Research progress in adsorbtion desulfurization for technology FCC gasoline

吸附脱硫法是一种低成本、易操作、开发应用前景广阔的制备清洁汽油方法。论述了FCC汽油吸附法深度脱硫常用吸附剂有分子筛吸附剂、金属氧化物吸附剂、活性炭吸附剂以及其他一些新型吸附剂的研究进展,指出了吸附剂要实现工业化还须攻克的难题和未来的吸附脱硫剂应该具有稳定硫容、运行周期长、装剂量小、空速高等特点。

Adsorption desulfurization is method that low cost, easy operation and having promising devel- opment and application for cleaning gasoline. Some common adsorbents were reviewed, such as the adsor- bents of zeolite, metal oxide, active carbon and other adsorbents. Points out that realizing the adsorbents into industrialization need to conquer some problems. At last, the characters of future adsorbents such as stable sulfur capacity, long operation cycle, small dosage and higher airspeed were proposed.
