cracking over Ga2O3/ZSM-5 reached to 87.6%, which was 56.3% higher than that over ZSM-5 [65]. Fu et al. [66] prepared two zeolites with different morphologies (nano-sphere and nano-rod crystallite aggregation) but with the same acid properties. The nano-sphere crystallite aggregate ZSM-5 zeolite showed better catalytic activity than that of nano-rod crystallite aggregate ZSM-5 zeolite, due to its Chaigtahlyestrs d20i1ff7u, 7s,i3o6n7 efficiency and acid sites accessibility originated from its larger external surfac1e1 aofn3d1 mesopore volume.

Copyright Royal Society of Chemistry, 2016. 3. Hierarchical ZSM-5 Zeolite 3. Hierarchical ZSM-5 Zeolite Due to the lower diffusion efficiency in micropores for the conventional ZSM-5 zeolite, much Due to the lower diffusion efficiency in micropores for the conventional ZSM-5 zeolite, much work has been done to design ZSM-5 zeolite with hierarchical porous structure to enhance the work has been done to design ZSM-5 zeolite with hierarchical porous structure to enhance the diffusion diffusion of reactants and accessibility of acid sites [14,67,68]. Garcia-Martinez et al. [19] revealed the of reactants and accessibility of acid sites [14,67,68]. Garcia-Martinez et al. [19] revealed the nature nature of intracystalline mesopores and its connectivity by electron tomography, three-dimensional of intracystalline mesopores and its connectivity by electron tomography, three-dimensional rotation rotation electron diffraction, and high resolution gas adsorption coupled with hysteresis scanning electron diffraction, and high resolution gas adsorption coupled with hysteresis scanning and density and density functional theory. The intracystalline mesopores could act as fast channel to connect the functional theory. The intracystalline mesopores could act as fast channel to connect the micropores micropores and promote the transformation of molecules, thus enhance the catalytic performance and promote the transformation of molecules, thus enhance the catalytic performance and restrain and restrain the generation of carbon deposition. It has been proven that the hierarchical ZSM-5 the generation of carbon deposition. It has been proven that the hierarchical ZSM-5 zeolite have a zeolite have a better catalytic cracking performance due to the enhanced diffusion rates and acid better catalytic cracking performance due to the enhanced diffusion rates and acid sites accessibility sites accessibility compared with conventional ZSM-5 zeolite [18,69]. Double templating with compared with conventional ZSM-5 zeolite [18,69]. Double templating with hard-template method, hard-template method, double templating with soft-template method, single template method and double templating with soft-template method, single template method and post-treatment method are post-treatment method are all feasible for preparing the hierarchical zeolite. The textural properties all feasible for preparing the hierarchical zeolite. The textural properties of hierarchical ZSM-5 zeolite of hierarchical ZSM-5 zeolite are shown in Table 3. are shown in Table 3. Table 3.

Infinity Supercritical CO2 10 Liter Extractor Design and Worldwide Rights: The Infinity Supercritical 10L CO2 extractor is for botanical oil extraction, which is rich in terpenes and can produce shelf ready full spectrum oil. With over 5 years of development, this industry leader mature extractor machine has been sold since 2015 and is part of many profitable businesses. The process can also be used for electrowinning, e-waste recycling, and lithium battery recycling, gold mining electronic wastes, precious metals. CO2 can also be used in a reverse fuel cell with nafion to make a gas-to-liquids fuel, such as methanol, ethanol and butanol or ethylene. Supercritical CO2 has also been used for treating nafion to make it more effective catalyst. This NFT is for the purchase of worldwide rights which includes the design. More Info
