介孔炭-HY分子筛复合型脱硫吸附剂的制备与性能
Preparation and Performance of OMC-HY Composite Desulfurization Adsorbent
摘要
Abstract
The ordered mesoporous carbon (OMC)-HY zeolite composite material was synthesized, and the composite material was characterized X-ray diffraction, specific surface area measurement by nitrogen adsorption stripping, Fourier infrared spectroscopy, NH3-temperature programmed desorption, scanning electron microscopy and transmission electron microscopy, respectively. The result shows that the OMC-HY composite material exhibits a micro-mesoporous pore size distribution, and the specific surface area of the composite material increases when acid increases. The composite material can be used as an adsorbent to remove dibenzothiophene. It is indicated that the thermodynamic process of OMC-HY composite material follows the Langmuir adsorption isotherm models, and the adsorption kinetics follows the pseudo-second-order reaction model.关键词
