Development of catalysts for direct non-oxidative methane aromatization

Autor: Yuji Ogawa, Yuebing Xu, Zhanguo Zhang, Hongtao Ma, Yo Yamamoto

Publikováno v: Resources Chemicals and Materials, Vol 1, Iss 1, Pp 80-92 (2022)

Direct catalytic conversion of methane to benzene at non-oxidative condition is considered as one of key reactions for constitution of sustainable carbon-cycling processes, since either biomethane or CO2-based synthetic methane can serve as its feed

Publikováno v: The Journal of Cell Biology

Autophagosomes engulf a variety of targets, from a portion of cytosol to large organelles, by regulating the size of the autophagosomal membrane. Yamamoto et al. identify ERdj8, a novel ER membrane protein that affects the size of autophagosomes.

NGU: Development of a two-bed circulating fluidized bed reactor system for nonoxidative aromatization of methane over Mo/HZSM-5 catalyst

Autor: Hongtao Ma, Yang Song, Yo Yamamoto, Zhan-Guo Zhang, Yuebing Xu

Publikováno v: Environmental Progress & Sustainable Energy. 35:325-333

A laboratory-scale two-bed circulating fluidized bed reactor system was developed for processing the Mo/HZSM-5 catalyzed methane dehydroaromatization reaction in continuous catalyst-regeneration mode. A binder-free, spherical-shaped fluidizable Mo/HZ

Development of highly active coated monolith SCR catalyst with strong abrasion resistance for low-temperature application

Autor: Yo Yamamoto, Jian Yu, Hongtao Ma, Yoshizo Suzuki, Zhan-Guo Zhang, Shan Lei, Guangwen Xu, Lina Gan

Publikováno v: Frontiers of Environmental Science & Engineering. 9:979-987

Monolith SCR catalysts coated with V2O5-WO3/TiO2 were prepared by varying binder and coating thickness. Comparing with a monolith extruded with 100% V2O5-WO3/TiO2 powder, a coated monolith with a catalyst-coating layer of 260 µm in thickness exhibit

Performance of a binder-free, spherical-shaped Mo/HZSM-5 catalyst in the non-oxidative CH4 dehydroaromatization in fixed- and fluidized-bed reactors under periodic CH4–H2 switch operation

Autor: Yo Yamamoto, Zhan-Guo Zhang, Hongtao Ma, Yoshizo Suzuki, Jiangyin Lu, Yuebing Xu

Publikováno v: Chemical Engineering and Processing: Process Intensification. 72:90-102

There is a need to develop a fluidizable Mo/HZSM-5 catalyst for industrial application of the non-oxidative CH 4 conversion to benzene. A binder-free, spherical-shaped Mo/HZSM-5 catalyst was applied for the first time to the non-oxidative CH 4 dehydr

SCR catalyst coated on low-cost monolith support for flue gas denitration of industrial furnaces

Autor: Guangwen Xu, Juan Yang, Jian Yu, Zhan-Guo Zhang, Yo Yamamoto, Yoshizo Suzuki, Hongtao Ma

Publikováno v: Chemical Engineering Journal. 230:513-521

NH3-SCR honeycomb catalyst was prepared by coating powdery active metal components on the surface of blank monolith supports and tested at the temperatures of 250-350 degrees C, and superficial gas velocities of 5.3-6.3 m/s. The tests were performed

Optimal winding arrangement of a surface-mounted permanent magnet motor for torque ripple reduction

Autor: Akira Chiba, Takaaki Oiwa, Junichi Asama, Yo Yamamoto

Publikováno v: 2016 IEEE Energy Conversion Congress and Exposition (ECCE).

We are aiming to develop a high precision micro-milling machine with a high speed spindle which is driven by a permanent magnet motor and supported by active magnetic bearings. The torque ripple, however, has influence on the positioning accuracy. As

Autor: Yuebing Xu, Yoshizo Suzuki, Hongtao Ma, Zhan-Guo Zhang, Yo Yamamoto

Publikováno v: Journal of Natural Gas Chemistry. 21:729-744

Three industry-supplied, well-shaped Mo/HZSM-5 catalysts, two binder-added and one binder-free, were tested for the first time in methane dehydroaromatization to benzene at 1073 K and 10000 mL/(gh) in periodic CH4-H2 switch operation mode, and their
