A systematic study of two-staged upgrading process of vacuum residue for light fuel production has been carried out in a semi-batch binary reactor apparatus over Y, ZSM-5 and alkaline treated ZSM-5 zeolites. Prepared catalyst samples were characterized with XRD and BET. Density and Viscosity physical properties parameters estimation, as well as GC/SIMDIS analyses were conducted on liquid produc...

Zeolites are microporous aluminosilicates with well-defined channels and cavities. They have been widely used as ionexchangers, molecular sieves, sorbents, and catalysts. The stability of zeolites is crucial to their applications. Many experimental and theoretical studies have been concentrated on their thermal stability. On the contrary, their behavior under external high pressures has receive...

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...

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...

Comparative studies over micro-/mesoporous Cu-containing zeolites ZSM-5 prepared by top-down treatment involving NaOH, TPAOH or mixture of NaOH/TPAOH (tetrapropylammonium hydroxide) were conducted. The results the catalytic data revealed highest activity Cu-ZSM-5 catalyst both in absence and presence water vapor. physico-chemical characterization (diffuse reflectance UV-Vis (DR UV-Vis), Fourier...
