چکیده
In this study, hierarchical NaP zeolite was prepared for dehydration of a wet nitrogen gas stream using an adsorption system. Hierarchical NaP zeolite was synthesized via an easy hydrothermal process and characterized using several techniques such as scanning electron microscopy (SEM), X-ray diffraction (XRD), BET surface area analysis and Fourier transform infrared (FT-IR) spectroscopy. An adsorption system comprising a desiccant packed column, humidity analyzer, and dry and wet gas cylinders was designed to evaluate the adsorption behavior of the synthesized NaP zeolite. Results indicated that hierarchical structure of NaP zeolite made a high surface area for water removal from a non-corrosive gas stream at ambient condition as it could reduce the water content of the gas from an initial concentration of 53 ppmv to approximately 5 ppmv after just one minute of the experiment.

چکیده [English]
چکیده
در این پژوهش، زئولیت سلسله مراتبی NaP جهت خشک نمودن جریان گاز نیتروژن مرطوب با استفاده از یک سیستم جذب سطحی تهیه شد. زئولیت سلسله مراتبی NaP از طریق یک فرآیند هیدروترمال آسان سنتز و با استفاده از تکنیک­های مختلف مانند میکروسکوپ الکترونی روبشی (SEM)، پراش اشعه ایکس (XRD)، آنالیز مساحت سطح BET و طیف­سنجی تبدیل فوریه مادون قرمز (FT-IR) مشخصه­یابی گردید. به علاوه، یک سیستم جذب سطحی متشکل از ستون خشک­کن، آنالایزر رطوبت و سیلندرهای گازی خشک و مرطوب به منظور ارزیابی رفتار جذبی زئولیت NaP تهیه شده، طراحی گردید. نتایج نشان داد که ساختار سلسله مراتبی زئولیت NaP مساحت سطح بالایی را برای حذف آب از جریان گازی غیر خورنده در شرایطی محیطی فراهم آورده است به طوری که تنها پس از گذشت یک دقیقه از زمان آزمایش، محتوای آب موجود در جریان گازی از غلظت اولیه  ppmv53 به حدود  ppmv 5 تقلیل یافت.
