Methane adsorption on Mo/HZSM-5 and Pd-Ga/HZSM-5 was investigated by TPD. Even at 323 K, methane could adsorb on the catalysts. It dissociated transferred to the high hydrocarbons with temperature increase. The enough concentration of intermediates is necessary step for aromatics formation. The higher ability of hydrogenation over Pd-Ga/HZSM-5 than that over Mo/HZSM-5 was probably the reason for the rich in hydrogenation products and the lack of H 2 .
According to the independence of the base station, the basic characteristics of the base station are analyzed, and a heat transfer model of communication base station enclosing structure is constructed, and the change of the temperature data in the base station is simulated using computer, and also all program module design flows of computer simulation are provided. Through the comparison between the result of field test on a typical base station and the simulation data, it is learnt that the temperature data simulated in the heat transfer model of the base station enclosing structure is similar to the average temperature within the measured base station.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
