در کار حاضر، کاتالیستهای نانوساختار SAPO-34 و ZSM-5 از کاتالیستهای شناخته شده برای فرآیند تبدیل متانول به الفینهای سبک (MTO) هستند. کاتالیست SAPO-34 انتخابپذیری بالایی برای الفینهای سبک دارد و کاتالیست ZSM-5 دارای پایداری بالایی است. ترکیبی از این کاتالیستها میتواند منجر به تولید یک کاتالیست کامپوزیتی با انتخابپذیری و پایداری بهینه شود. در این مطالعه کاتالیست کامپوزیتی SAPO-34/ZSM-5 با ...
Effect of acidity and physical properties of nanozeolite catalyst on hydrocracking of vacuum gas oil
In this study, beta nanozeolite, ultra-stable Y zeolite (USY) and amorphous silica-alumina (ASA) were synthesized. These compounds were used as the support of hydrocracking catalyst. Ni-Mo/beta zeolite-ASA and Ni-Mo/USY zeolite-ASA catalysts were prepared by the impregnation method. The samples were characterized with X-Ray diffraction (XRD), field emission-scanning electron microscopy (FE-SEM)...
The structure and reactivity of a room temperature stable zinc carbonyl complex in Zn-modified H-ZSM-5 zeolite were revealed by solid-state NMR spectroscopy.
This study aimed to valorize microcrystalline cellulose (MCC) using protonated zeolite catalysts such as (H-ZSM-5) and Cr/H-ZSM-5 (5%) in ionic liquid. The catalytic effect synergy with 1-butyl-3-methylimidazolium Chloride ([BMIM] Cl) liquid was studied detail. total reducing sugar (TRS) determined the 3, 5-dinitrisalcylic acid (DNS) array method. were characterized techniques Fourier transform...
Hydrogen rich products from waste HDPE/LDPE/PP/PET over Me/Ni-ZSM-5 catalysts combined with dolomite
Controlled nanozeolite deposits are prepared by electrochemical techniques on a macroporous carbon support and binderless thin film electrodes of zeolite-templated carbon are synthesized using the deposits as templates. The obtained film electrodes exhibit extremely high area capacitance (10-12 mF cm(-2)) and ultrahigh rate capability in a thin film capacitor.
In order to improve the adsorption performance of molecular sieve honeycomb ceramics for VOCs, author proposes a research method VOCs based on loaded with sieves. The prepared cordierite ceramic-supported HY, Na Y, USY, ZSM-5-300, and ZSM-5-360 monolithic materials by coating method. Using toluene, ethyl acetate, isopropanol, acetone as adsorbates, properties single-component mixed-component or...
