Impregnated Carbons for the Adsorption of H2s and Mercaptans
Activated carbon has been used for many years for the adsorption of H2S and Mercaptans from natural gas streams, carbon dioxide, and sewage vents. It is widely thought that the carbon pore surface catalyses the oxidation of HzS to elemental sulfur and higher oxidized forms of su l fd2 . However, due to the poor loading capacities achieved at ambient conditions, most commercial activated carbon ...
متن کاملCO2 adsorption by activated templated carbons.
Highly porous carbons have been prepared by the chemical activation of two mesoporous carbons obtained by using hexagonal- (SBA-15) and cubic (KIT-6)-ordered mesostructured silica as hard templates. These materials were investigated as sorbents for CO(2) capture. The activation process was carried out with KOH at different temperatures in the 600-800°C range. Textural characterization of these ...
متن کامل2001: Characterization of Activated Carbons Using Liquid Phase Adsorption
The pore size distribution is the most important aspect in characterization of structural heterogeneity of porous materials. Different methods have been developed and applied for the characterization of this property, and the most often used is gas adsorption [1,2], while liquid phase adsorption is seldom used [3]. A modification of the Dubinin-Radushkevich pore filling by incorporation of the ...
متن کاملa comparative study of language learning strategies employmed by bilinguals and monolinguals with reference to attitudes and motivation
هدف از این تحقیق بررسی برخی عوامل ادراکی واحساسی یعنی استفاده از شیوه های یادگیری زبان ، انگیزه ها ونگرش نسبت به زبان انگلیسی در رابطه با زمینه زبانی زبان آموزان می باشد. هدف بررسی این نکته بود که آیا اختلافی چشمگیر میان زبان آموزان دو زبانه و تک زبانه در میزان استفاده از شیوه های یادگیری زبان ، انگیزه ها نگرش و سطح مهارت زبانی وجود دارد. همچنین سعی شد تا بهترین و موثرترین عوامل پیش بینی کننده ...
15 صفحه اولPreparation, characterization and phenol adsorption capacity of activated carbons from African beech wood sawdust
In the present study, different activated carbons were prepared from carbonized African beech wood sawdust by potassium hydroxide activation. The activated carbons were characterized by brunauer–emmett–teller, scanning electron microscope, fourier transform infrared spectroscopy, and thermogravimetric analyzer. The phenol adsorption capacity of the prepared carbons was evaluated. The d...
