M. O. Kalinkin, M. Yu. A highly oxidized Pd deposited on ceria could produce ethane with a productivity as high as 0.84 mmol g cat −1 h −1.

Thus, the solid support can be chosen from sulphated metal oxides or sulphated refractory oxides, for example a sulphated alumina or a sulphated zirconia.

The good OCM catalytic properties of BYS are believed to be related to its fluorite-type phase structure and large oxygen ion mobility at high temps. benzene), of carbon monoxide and/or of carbon dioxide.

A second subject-matter of the invention is a process for the conversion of methane to carbon-containing products, characterized in that methane is brought into contact with a metal catalyst comprising at least one metal, Me, chosen from the lanthanides, the actinides and the metals from Groups 2 to 12, preferably 3 to 12, of the Periodic Table of the Elements, so as to produce ethane in a proportion of at least 65% by weight with respect to carbon-containing products formed in the process. It can also be a matter of a carbon-metal triple bond: in this case, the hydrocarbon radical, R, can be an alkylidyne radical, in particular a linear or branched radical, for example a C1 to C10, preferably C1, radical, or an aralkylidyne radical, for example a C7 to C14 radical. However, in addition to ethane, large amounts of ethylene and acetylene are formed, which products often constitute the major products formed by the reaction. A dense membrane tube was fabricated using a plastic extrusion technique. Working off-campus? CHFMMR and a washcoat CHFMMR are highlighted.

As stated in M. Farooq's answer, this nomenclature was introduced by A. W. Hofmann in 1865.
Methane reacts with a mixed Mn-Mg oxide above 800° to give higher hydrocarbons as well as CO2. Ojotule P. Onoja, Xiaodong Wang, Panagiotis N. Kechagiopoulos.
The German Patent Application is silent about the ethane production compared with the formation of the other higher hydrocarbons. Yujin Sim, Inchan Yang, Dahye Kwon, Jeong-Myeong Ha, Ji Chul Jung. This community is not edited and does not necessarily reflect the views of Nature Research. It is considered that the selectivity by weight for ethane is generally at least 65%, preferably at least 70%, in particular at least 80%, especially at least 90%, and more especially at least 95%. strength (113.22 MPa). Operating a LaSr/CaO modified membrane reactor at 950° with a CH4 concn. Powered by. Such dependencies are different for membranes with oxygen permeation controlled by p-type electron transport and those by n-type electron or oxygen vacancy transport. More particularly, the solid support can be an oxide, in particular an oxide of M, and can be chosen from simple or mixed oxides, in particular simple or mixed oxides of M, or mixtures of oxides, in particular mixtures of oxides M. The solid support can, for example, be chosen from metal oxides, refractory oxides and molecular sieves, in particular from silica, alumina, silicoaluminates, aluminium silicates, simple or modified by other metals, zeolites, clays, titanium oxide, cerium oxide, magnesium oxide, niobium oxide, tantalum oxide and zirconium oxide. This process is also called Wrutz synthesis. Link to the manuscirpt: https://doi.org/10.1038/s41560-020-0616-7.
