[ 1 ] - اثر Mo و Zr بر کاتالیزور Pt-HMS در ایزومریزاسیون n-هپتان برای بالا بردن عدد اکتان
کاتالیزورهای پلاتین بر پایهZr-HMS با نسبتهای مولی مختلف تهیه و به منظور اصلاح سطح، مولیبدن به عنوان بهبود دهنده به آن اضافه و در واکنش ایزومریزاسیون کاتالیزوری n-هپتان در محدوده ی دمایی °C500-200 به کار گرفته شد. برای شناسایی از تکنیک پراش اشعه ایکس استفاده شد و تأثیر پارامترهای دما و نسبت Si/Zr بر روی فعالیت و گزینش پذیری کاتالیزورها مورد بررسی قرار گرفت. نتایج حاصل نشان می دهد که کاتالیزورهای...
[ 2 ] - Studying of Catalyst Deactivation in a Commercial Hydrocracking Process (ISOMAX)
Catalyst deactivation is usually indispensable, although the rate at which it occurs varies greatly. At first, this article discusses the causes of deactivation in a commercial hydrocracking unit called Isomax. Then, a 5-lump kinetic model including catalyst decay function for hydrocracking of vacuum gas oil in a commercial plant is proposed. The model considers vacuum gas oil (VGO) having boil...
[ 3 ] - Influence of synthesis parameters on the properties of nanostructured γ-Alumina using plackett-burman experimental design
Mesoporous nanostructured γ-Al2O3 powders were synthesized through multi- step precipitation procedures using the pH-swing technique. Structural and morphological characteristics in addition to the thermal behavior of the procured samples were characterized via X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), fourier transform infrared (FT-IR) ...
