Synthesis and Characterization of Amine-modified Mesoporous SBA-15 for Carbon Dioxide Sequestration at High Pressure and Room Temperature (RESEARCH NOTE)
Amine-modified mesoporous SBA-15 adsorbent has been prepared by impregnation method using tetraethylenepentamine. The samples of this modified SBA-15 have been characterized by small angle X-ray scattering (SAXS), Scanning electron microscopy (SEM), Nitrogen adsorption-desorption isotherm and FT-IR. The adsorption capacity of CO2 on unmodified and modified samples were measured at high pressure...
متن کاملPalladium-gold catalysts for H2O2 direct synthesis at room temperature and atmospheric pressure
Introduction Hydrogen peroxide has always been considered a very interesting and environmentally friendly oxidant with applications confined mainly in unselective sectors such as the paper and textile industry and the treatment of waste waters. More recent applications, related to the discovery of TS-1 molecular sieve, are in the large scale selective oxidation processes for the chemical indust...
متن کاملHydroxy-functionalized hyper-cross-linked ultra-microporous organic polymers for selective CO2 capture at room temperature
Two hydroxy-functionalized hyper-cross-linked ultra-microporous compounds have been synthesized by Friedel-Crafts alkylation reaction and characterised with different spectroscopic techniques. Both compounds exhibit an efficient carbon dioxide uptake over other gases like N2, H2 and O2 at room temperature. A high isosteric heat of adsorption (Qst) has been obtained for both materials because of...

چکیده یکی از پارامترهای اصلی در دنبال کردن تاریخچه ی تشکیل ستاره ها و تحول کهکشان ها، مطالعه ی میزان فراوانی عناصر آن ها است. در این پایان نامه برای مطالعه ی همبستگی میان فراوانی فلزی و جرم ستاره ای کهکشان ها، از داده های طیفی 89 کهکشانِ ستاره زا استفاده شده است. طیف ها توسط طیف نگار فورس2 از میدان ژرف جنوبی چاندرا گرفته شده و جابه جایی به سرخ طیف ها همه بزرگتر از نیم و کوچکتر از یک هستند. جر...
15 صفحه اولComparison of Tribological Behavior of Deep Cryogenic Treated Hot Work Tool Steel at Room and High Temperature
The deep cryogenic treatment is a complementary operation that is done on a variety of tool steels aimed at improving their abrasion resistance and hardness. In the case of the H13 hot-work steel, which is widely used at high temperatures as a hot-deformation tool, we need to determine the efficiency of subzero treatment on it at the working temperature. In this regard, this paper is focu...
