[ 1 ] - تعیین سینتیک ذاتی واکنش فیشر- تروپش بر روی کاتالیست کبالت - رنیوم بر پایه ترکیبی گاما آلومینا- زیرکونیا

سینتیک ذاتی فرآیند فیشر- تروپش شامل تبدیل گاز سنتز به هیدروکربن‌های مایع و محصولات میان‌تقطیر با استفاده از کاتالیست Co-Re/Zr-Al2O3 در یک راکتور بستر ثابت به روشTaguchi مطالعه شد. تست‌های راکتوری در محدوده دمای 240-200 فشار 30-15 بار و نسبت H2/CO در محدوده 5/2-1 و میزان WHSV برابر با nL/g Cat.hr 5/1-5/0 انجام شدند. جهت ارائه مدل سینتیکی مناسب مصرف واکنش‌دهنده‌ها، نخست تعدادی مکانیسم‌ که به عنوا...

[ 2 ] - Scanning hall probe microscopy technique for investigation of magnetic properties

Scanning Hall Probe Microscopy (SHPM) is a scanning probe microscopy technique developed to observe and image magnetic fields locally. This method is based on application of the Hall Effect, supplied by a micro hall probe attached to the end of cantilever as a sensor. SHPM provides direct quantitative information on the magnetic state of a material and can also image magnetic induction under a...

[ 4 ] - Kinetic Modelling of Methanol to Propylene Process on Cerium-hierarchical SAPO-34 Catalyst

In this paper, conventional SAPO-34 and Cerium Hierarchical SAPO-34 zeolites are synthesized using a hydrothermal method for methanol-to-propylene (MTP) reaction. The Ce-H-SAPO-34 catalyst shows a slightly larger crystal size, bimodal pore size distribution (microporous and mesoporous) and lower surface acidity compared to conventional SAPO-34 catalysts. According to these physicochemical prope...
