Mesoporous high-silica zeolite Y with advantages of improved accessibility acid sites and mass transport properties is highly desired catalytic materials for oil refinery, fine chemistry emerging biorefinery. Here, we report the direct synthesis mesoporous (named MSY, SiO2/Al2O3 ? 9.8) their excellent cracking performance. The obtained MSY are single crystals octahedral morphology, abundant mes...

Abstract Catalytic/initiated cracking of endothermic hydrocarbon fuels is an effective technology for cooling a hypersonic aircraft with high Mach number (over 5). Catalysts and initiators can promote fuel at low temperatures, increase conversion the heat sink capacity, suppress coke deposition, thereby reducing waste heat. mainly include metal oxide catalysts, noble catalysts nanoparticles, ze...

Abstract Acetone is a solvent used in many laboratories and factories. Serious problems will occur when it exposed to the environment. Therefore, new design hydrophobicity bimetallic metal material (10-Fe 1 Mn -USY) was prepared for acetone adsorption under conditions of high humidity. Hydrophobic Y type zeolite prepare materials effect different operating parameters (including material, humidi...

In this investigation we synthesized NaX-Nanozeolite by hydrothermal crystallization conditions.These nanoparticles were prepared at different conditions in a temperature controlled shaker. Thesynthesized zeolites were characterized by instrumental analysis methods, such as X-raydiffraction (XRD), X-ray fluorescence (XRF), scanning electron microscopy (SEM) andtransmission electron microscopy (...

The plasma-catalytic oxidation of soot was studied over zeolite-supported vanadium catalysts, while four types zeolites (MCM-41, mordenite, USY and 5A) were used as catalyst supports. rate followed the order V/MCM-41 > V/mordenite V/USY V/5A, 100% achieved at 54th min reaction V/mordenite. CO2 selectivity process follows opposite V/M catalyst. A wide range characterizations including N2 adso...

in this investigation we synthesized nax-nanozeolite by hydrothermal crystallization conditions.these nanoparticles were prepared at different conditions in a temperature controlled shaker. thesynthesized zeolites were characterized by instrumental analysis methods, such as x-raydiffraction (xrd), x-ray fluorescence (xrf), scanning electron microscopy (sem) andtransmission electron microscopy (...
