In this present work, HZSM-5 zeolite was synthesized by two-steps process. Firstly, the reactant mixtures were pre-heated by microwave radiation under five different microwave powers in the range of 400?1200 W for 1 min. Then, the pre-heated mixtures were further crystallized under hydrothermal condition at 160 C for 24 h. HZSM-5 zeolites treated by microwave power at 800 and 1000 W had high crystallinity and surface area (407?412 m2/g) and were used to evaluate the catalytic performance. Non- and catalytic fast pyrolysis of Jatropha residues using HZSM-5 zeolites synthesized by microwave heating were investigated using an analytical pyrolysis-GC/MS at 500 C with different biomass to catalyst ratios of 1:1, 1:5, and 1:10. After catalytic process, HZSM-5 catalysts remarkably promoted the formation of aromatic hydrocarbon, especially BTX compounds. HZSM-5 treated by microwave at 800 W revealed high catalytic performance on upgrading of pyrolytic vapors resulting in the highest selectivity of aromatics, 94%, which are usually considered to be valuable products because of their high heating values. In addition, it decreased unfavorable oxygenated and nitrogenated compounds to 1.3% and 2.8%, respectively at moderate biomass to catalyst ratio of 1:5. HZSM-5 treated by microwave energy also exhibited superior performance in terms of aromatic selectivity (94%) compared to conventionally processed HZSM-5 (72%). The results showed that HZSM-5 prepared by microwave assisted synthesis was an effective catalyst for fast pyrolysis application.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Reference of 1941-30-6, you can also check out more blogs about1941-30-6

Zeolite ZSM-5 is one of the major catalysts in the petroleum and finechemical industries. The synthesis of zeolite ZSM-5 is usually carried out at a temperature above 100 C using an immense amount of organic structuredirecting agents (OSDA). It is interesting to note that fine-tuning the initial gel mixture can be used to enhance the typical slow crystallization rate of ZSM-5. Herein, we report the effect of the surface-to-volume ratio of the reactor vessel on the crystallization of ZSM-5 at low temperature. The surface-to-volume ratio of the reactor vessel influences the heat-transfer during the synthesis, which further governs the crystallization of ZSM-5. It was found that the higher the surface-to-volume of the reactor, the more crystalline the resulting product. The products with the highest crystallinity exhibited a nearly spherical morphology composed of smaller ZSM-5 crystallites. This phenomenon allows the presence of inter-crystallite mesopores, which is an advantage for the catalytic reaction of bulky molecules.

Zeolite ZSM-5 has been successfully produced from rice-husk by a low-cost process. Without expensive and toxic organic structure-directing agent, zeolite ZSM-5 can be obtained at temperature of 160 C, in 96 h at pH 11 by a seed-assisted hydrothermal method. Using this zeolite as a support, nano-sized TiO2/ZSM-5 photocatalysts were obtained by sol?gel method. The materials were characterized the structural and morphological properties. They were also examined activity for photocatalytic removal of toluene in humid condition. Synergistic adsorption?photocatalysis using TiO2/ZSM-5 can remove about 70% toluene at its concentration of 2400 ppm, water vapor content of 18.5 mg/L (relative humidity 60% at 25 C), and gas hourly space velocity (GHSV) of 5760 h?1. The toluene removal efficiency by the nano-sized TiO2/ZSM-5 photocatalyst was significantly higher than that by a commercial photocatalyst TiO2. The toluene removal in humid condition was remarkably enhanced on TiO2/ZSM-5 due to combination adsorption (on ZSM-5)?photocatalysis (on TiO2).

Zeolite ZSM-5 have been synthesized by hydrothermal method, using tetrapropylammonium bromide as template. This work aims to evaluate the preparation and characterization structural and morphology of zeolite ZSM-5 resulting in a pure and crystalline material. The ZSM-5 zeolite was prepared by hydrothermal synthesis at 170C, using silica, deionized water and structure-directing salt (tetrapropylammonium bromide-TPABr). Several techniques like X ray diffraction (XRD), scanning electron microscopy (SEM) and X ray energy dispersion spectrophotometer (EDX) have been utilized to characterize the framework structure and morphology of the sample. Obtaining ZSM-5 zeolite could be confirmed by X ray diffratograms. The result X ray diffraction showed that the synthesized sample presented typical peaks of the ZSM-5 zeolite. According to the XRD, it is possible to observe intense and well defined peaks. The acquired X ray patterns identified the product as highly-crystalline materials, without the presence of impurities. From the images obtained by SEM, it was possible are composed of showed that the crystal accumulations of ZSM-5 zeolite, without the presence secondary phases on the crystals.

The electrical conductivity of mixed-valence [MoV2MoVI16O54(SO3)2]6- tetraalkylammonium salts was investigated through dependence on the inter-cluster distance that is controlled by tetraethylammonium, tetrapropylammonium, and tetrabutylammonium cations. The crystallographic analysis of single crystals revealed that the inter-cluster distances are dependent on the chain length of the alkyl groups on the counter cations. In addition, the electrical conductivities of the single crystals were found to be dependent on both temperature and chain length. Mixed-valence polyoxometalate (POM) clusters are considered to be a molecular particle of Mo bronze by which highly ordered networks will be developed using single crystals, where POMs are rather small and have a well-organized structure compared to colloidal nanostructures.

We present structural and magnetic data on the series of compounds AMnIIFeIII(c2s2 O2)3 with A = N(CnH2n+1)4 (n =3-5) or P(C6H5)4. The tetra-alkyl ammonium compounds are all ferromagnets with Tc = 10 K, whilst the tetraphenyl phosphonium compound is a ferrimagnet with TN = 15 K. EXAFS spectroscopy shows that there is significant disorder in the orientation of the dithio-oxalate moiety, while high resolution X-ray powder diffraction measurements prove that the dithio-oxalate materials are structurally analogous to the layered oxalates.

Using silicalite-1 suspension as seed crystals and a small amount of tetraallkylammonium bromide as additional structure-directing agent, highly crystallized ZSM-5 with SiO2/Al2O3 ratios higher than 100 was obtained. The crystal sizes could be easily tuned from tens of nanometers to about several micronmeters by merely adjusting the amount of the seeding suspension. Seeding suspension synthesized from different silica sources and the additional structure-directing agent may also affect the crystal sizes. The synthesized samples were characterized by powder X-ray diffraction, scanning electron microscopy, N2 adsorption-desorption and inductively coupled plasma. When tetraethylammonuim bromide was used as additional structure-directing agent, crystals with silica-rich cores were observed, while additional nucleation could be found when tetrapropylammonium bromide was used as auxiliary template.

We report for the first time phonon properties of [(C3H7)4N][M(N(CN)2)3] with M?Mn, Co, Ni (TPrAM), and theoretical Density Functional Theory (DFT) data for isolated TPrA+ cation obtained using harmonic and anharmonic approximation. Manganese compound undergoes one structural temperature-induced phase transition, whereas others exhibit multiple structural phase transitions in a broad temperature ranges. Temperature-dependent Raman studies let us obtain insight into mechanism of these transitions. The phase transition at about 330 K in TPrAMn involves mainly the ordering of the dca bridges coordinating Mn2+ ions and is accompanied by partial ordering of the TPrA+ cations and their shift in the cavities. However, the behavior of TPrANi is different. In particular, very large broadening of bands, attributed to vibrations of the dca and TPrA+ cations, revealed highly dynamic nature of these groups in all phases. This result indicates that observed phase transitions are associated with changing the dynamic disorder of both organic ions. Raman studies also show that all phase transformations are accompanied by slight modification in tilting of the NiN6 octahedra caused by shift of the TPrA+ ions in the cavities.
