One-pot synthesis of cup-like ZSM-5 zeolite and its excellent oxidative desulfurization performance

Ce-ZSM-11 Zeolite: An Efficient Heterogeneous Catalyst for One-Pot Synthesis of 4H-Pyran Derivatives

ZSM-11 zeolite was synthesized by hydrothermal treatment and cerium ion was incorporated by the ion exchange method.  The catalytic activity of cerium modified ZSM-11 zeolite was tested for the one-pot synthesis of 4H-pyran derivatives by cyclocondensation of aromatic aldehyde, malononitrile, and ethyl acetoacetate. The synthesized catalyst was characterized by Po...

Synthesis of Zeolite Y from Kaolin and Its Model Fuel Desulfurization Performance: Optimized by Box-Behnken Method

In this research, zeolite Na-Y was synthesized from Kaolin without an organic template under the non-hydrothermal condition to adsorb sulfur compound. Model fuel desulfurization was optimized by employing the Box-Behnken experimental design with 2 center points, the three parameters, and one response value. The objective was to find how sorption capacity is related to alkali fusion temperat...

Deep desulfurization of diesel by adsorption over Ni/ZSM-5

Introduction Environmental restriction regarding the quality of transportation fuels and the emissions from them are the most important issues. Because of more stringent regulations and fuel specifications regarding development of better method for deep-desulfurization of fuels are important. There has been recent interest in developing adsorbents for selective desulfurisation by adsorption. Me...

Microwave Synthesis of Fe2O3 Nanoparticles and Its Catalyst Investigation in One-pot Synthesis of Naphthoxazinone Derivatives

In this work firstly Fe2O3 nanoparticles were synthesized via a simple chemical method. Properties of the product were examined by X-ray diffraction pattern (XRD), Scanning electron microscope (SEM) and Fourier transform infrared (FT-IR) spectroscopy. Vibrating sample magnetometer (VSM) shows nanoparticles exhibit ferromagnetic behavior. To continue some of the 2-naphthol condensed 1,3-oxazinon...
