Oxidative coupling of methane over natural calcium compounds in fixed- and fluidized-bed reactors

Autor: Kazutoshi Chaki, Hideo Okado, Masami Yamamura, S. Suzuki, K. Inaba, T. Yoshinari, S. Okada, Toshiya Wakatsuki

Publisher Summary This chapter presents the catalytic performance of the natural calcium compounds (NCC) catalysts under various reaction conditions, using fixed- and fluidized-bed reactors. In an experiment presented in the chapter, the catalysts we

Natural Calcium Compounds as Catalysts for Oxidative Coupling of Methane

Autor: K. Inaba, Toshiya Wakatsuki, Kazutoshi Chaki, S. Suzuki, Masami Yamamura, Naohide Tsuzuki, Hideo Okado, S. Kitada

Oxidative coupling of methane(OCM) over various natural calcium compounds was investigated. Some kinds of shells were found to be good catalysts for OCM. The study of surface properties of the catalysts by XPS revealed that a high performance of the

Oxidative coupling of methane over sodium-doped CaO catalysts prepared by the sol-gel method

Autor: Kazutoshi Chaki, Masami Yamamura, S. Suzuki, T. Yoshinari, Toshiya Wakatsuki, K. Inaba, Hideo Okado

Publikováno v: Catalysis Today. 24:299-300

Sodium-doped calcium oxide (Na/CaO) catalysts prepared by the sol-gel method (SGM) show relatively high performance for oxidative coupling of methane (OCM) compared with that prepared by impregnation method (IM). The difference between the performanc
