Rate-determining step of ammonia synthesis and decomposition. 4. Decomposition over a doubly-promoted iron catalyst at 430.deg.Yamamoto, OsamuTanaka, ShinyaTanaka, Kazunori
The effect of cobalt on the properties of cobalt modified iron fused catalyst for ammonia synthesis has been investigated by scanning electron microscopy, Mssbauer spectroscopy, X-ray diffraction (XRD), X-ray fluorescence spectroscopy (XRFS) and Auger electron spectroscopy (AES). Introduction of coba...
which monitored the conversion of BrCF2CONHPh and yields of the desired product1and byproduct1bover time either under the catalysis of Fe-catalyst or without catalyst. As shown in Fig.6e, compared to the non-catalytic system, the iron-catalyst significantly decreased the consumption-rate of the...
Adsorption of Cd2+ and Ni2+ on the iron oxide surface was found to be heterogeneous, and the mechanism of chemisorption is involved in the stage of determining the rate. The correlation coefficient R2 and error functions like RMSE, MES and MAE were used to evaluate the best fit models to ...
Synthesis and use of an asymmetric transfer hydrogenation catalyst based on iron(II) for the synthesis of enantioenriched alcohols and amines 来自 NCBI 喜欢 0 阅读量: 46 作者:W Zuo,RH Morris 摘要: The catalytic hydrogenation of prochiral ketones and imines is an advantageous approach to the ...
Hematite ore reduced with hydrogen was used as a catalyst in the present investigation of the rate of decomposition of carbon monoxide in H2-CO mixtures. It was found that the amount of carbon deposited from purified carbon monoxide was directly proportional to the amount of porous iron catalyst...
67. Alternative synthesis methods that create different Fe sites have been lacking. Here, the saturated adsorption of Fe(NO3)3onto the ZIF-8 matrix followed by pyrolysis enables the synthesis of a new Fe SA catalyst with ultra-low Fe loading (<0.1 wt%). Importantly, the Fe catalyst ...
The invention relates to the field of production of catalysts and, in particular, relates to a block of a granular promoted iron oxide catalyst for the synthesis of ammonia, and a process for the production thereof. The block of a catalyst has the following composition in % by weight: granul...
