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...

The performance of the adsorption cooling system using the zeolite 13X/CaCl2 composite adsorbent was studied using a numerical simulation. The novel zeolite 13X/CaCl2 composite adsorbent with superior adsorption properties was developed in previous studies [11]. It has high equilibrium water uptake of 0.404 g/g between 25C and 100C under 870Pa. The system specific cooling power (SCP) and coeffi...

This work presents a comparative study of microwave and conventional (conductive) heating for adsorbent regeneration. A binary gas mixture representative pre-dried flue from coal-fired power plants (15% v/v CO2 in N2) was passed through rotatory fixed-bed adsorption column filled with zeolite molecular sieve (13X) an activated carbon (Norit R2030CO2). The impact the two regeneration methods on ...

Infrared spectroscopy has been used in adsorption studies of trimethyl phosphite (TMP) on the hydrogen (H) form of the A-type and 13X zeolites. Infrared spectra of H-zeolites, except H-KA, show that TMP reacts rapidly with silanol hydroxyls on their surfaces and gives rise to form product molecules such as SiOCH3 and liquid dimethyl phosphite. The unaccomplished adsorption on the HKA zeolite ha...
