Efficient Hydrogenolysis of Guaiacol over Highly Dispersed Ni/MCM-41 Catalyst Combined with HZSM-5
A series of MCM-41 supported Ni catalysts with high metal dispersion was successfully synthesized by simple co-impregnation using proper ethylene glycol (EG). The acquired Ni-based catalysts performed the outstanding hydrogenolysis activity of guaiacol. The effects of the synthesis parameters including drying temperature, calcination temperature, and metal loading on the physical properties of ...
متن کاملEnhancement of photocatalytic degradation of 4-nitrophenol by integrating Ag nanoparticles with ZnO/HZSM-5 nanocomposite
In this paper, Ag/ZnO/HZSM-5ternary nanocomposites with different Ag loadings were prepared by the photo precipitation method. The prepared photocatalysts were characterized by XRD, BET, SEM and TEM. The photocatalytic activity of ZnO/HZSM-5 for 4-nitrophenol (4-NP) degradation was increased by silver doping. Effects of various parameters such as the initial concentration of 4-NP, pH and Ag loa...
متن کاملThe catalytic cracking of hydrocarbons: paraffins in the HZSM-5 zeolite.
An elementary reaction during cracking of a hydrocarbon in a nanoporous silicalite catalyst includes ejection of a hydrid ion as shown in the picture. The reaction was simulated by means of quantum molecular dynamics.
متن کاملCatalytic Investigation of Aluminum Effects on Benzene Hydrogenation Selectivity over Nickel Supported HMS/HZSM-5 Composites
Ni/Al-HMS/HZSM-5 catalysts with varying amounts of Si/Al ratios were prepared via the impregnation method and evaluated for the hydrogenation of benzene at 130−190 °C. To study the catalyst characterization, various methods were used as X-ray diffraction, X-ray fluorescence, Fourier transform infrared spectroscopy, ultraviolet-visible diffuse reflectance spectroscopy, temperature-programmed des...
متن کاملCatalytic Pyrolysis of Wild Reed over a Zeolite-Based Waste Catalyst
Fast catalytic pyrolysis of wild reed was carried out at 500 ̋C. Waste fluidized catalytic cracking (FCC) catalyst disposed from a petroleum refinery process was activated through acetone-washing and calcination and used as catalyst for pyrolysis. In order to evaluate the catalytic activity of waste FCC catalyst, commercial HY zeolite catalyst with a SiO2/Al2O3 ratio of 5.1 was also used. The b...
