催化裂化汽油固体碱预碱洗的研究──负载固体碱对硫化氢的吸附过程分析

STUDY ON PRETREATMENT WITH SOLID BASE OF FCC GASOLINE ADSORPTION PROCESS OF A SUPPORTED SOLID BASE FOR H2S

以活性炭为载体，碱金属化合物为活性组分，制备出负载固体碱，对其吸附硫化氢性能进行了研究。结果表明，此类固体碱吸附硫化氢能力较强，在固体碱孔外主要进行化学吸附，在固体碱孔内以物理吸附为主，化学吸附和物理吸附能力分别与固体碱。

With active carbon as supporter and alkali compound as active component, a novel solid base is prepared The adsorption process of the solid base for H2S is studied The results show that the adsorptive capacity of the solid base for H2S is high On the exterior surface of the solid base, chemical adsorption plays main role, while physical adsorption dominates in the pores of the solid base The chemical and physical adsorptive capacities are related to the loading quantity of "M
