در این تحقیق،فرآیند جذب گاز دی اکسیدکربن با استفاده از زئولیت13 در یک راکتور بستر ثابت مورد مطالعه قرار گرفت. آزمایش های جذب در یک بستر ثابت با ارتفاع 1 متر و قطر 10 سانتیمتر انجام گردید. آزمایشات جذب جهت بررسی پارامترهای عملیاتی شامل دما، فشار، دبی گاز و مقدار جاذب انجام گرفت. نتایج آنالیز ذرات جاذب نشان داد که متوسط قطر حفرات جاذب 92/1 نانومتر و سطح ویژه 697 مترمربع بر گرم می باشد. نتایج آزما...

Since the discovery of zeolites there has been a consistent interest in the potential applications of these microporous structures. Of current particular interest is the possible use of zeolites as storage devices for fuel cells in the hydrogen economy. The adsorption kinetics of zeolites are not fully understood, and therefore the potential of such materials has not been optimized. In this stu...

Thermal energy storage has received significant interest for delivering heating and cooling in both transportation and building sectors. It can minimize the use of on-board electric batteries for heating, ventilation and air-conditioning (HVAC) in electric vehicles (EVs) or reduce electricity consumption during peak demand in residential and commercial buildings. A compact and lightweight advan...

Sub-nanometer zeolite 13X-supported Ni-ceria catalysts were synthesized for CO2 methanation. XRD and SEM results show the structure morphology of 13X after impregnation calcination. Ce loading affected catalysts’ metal dispersion, reducibility, basicity acidity, thence their activity selectivity. STEM-EDX elemental mappings showed that Ni are predominantly highly dispersed. has a positive effec...

Usually, the ion implantation gases used in semiconductor production are required to be extremely high purity. Due presence of trace CO2 electronic special gas BF3, quality material is significantly affected, which makes it crucial impose control on content. Unlike a series blank adsorbents reported other studies, zinc-loaded prepared this study intended for adsorption from CO2/BF3. Firstly, ma...

Zeolite 13X molecular sieve with high sorption capacity and significant rate has been considered a promising candidate for seasonal heat storage. In this study, code is developed to simulate the adsorption process between zeolite water in all ranges of partial pressures, temperatures, sorbate loadings. The results from proposed were compared experiments good agreement was observed. After valida...

Oxygen is one of the most important products in chemical industries. This chemical element is used in various processes such as: refinery industries, manufacturing metal and other industrial operations. For instance, oxygen with high purity is utilized in different chemical processes like: steel construction, paper industries, wastewater treatment and glass production. In 1907, oxygen was produ...
