The activation of methane has been referred to as one of the central challenges in contemporary chemical research.[1] In addition to various academic aspects, methane activation is of eminent industrial importance. One economically attractive process is the coupling of ammonia and methane according to reaction (1) to afford hydrogen cyanide, a valuable feedstock for chemical synthesis. Reaction...

Oxidative coupling of methane (OCM) is a promising single-step route to convert natural gas high-valued chemicals. It generally agreed that Mn–Na–W catalysts offer balanced conversion–selectivity trade-off. The present work outlines novel SiC–SiO2 support synthesized by spray drying extend the lifetime catalyst. Incorporating SiC into enables exothermic reaction heat be effectively dissipated, ...

Oxidative coupling of methane and dehydroaromatization are attractive one-step conversion routes to make valuable platform chemicals more sustainable. Both processes require elevated temperatures above 600°C, good heat management, the use heterogeneous catalysts. None these reactions yet commercial due many technical challenges. This work explores potential combining two under one umbrella over...

The promoting effect of niobium in a Li/MgO catalyst for the oxidative coupling of methane (OCM) and for the oxidattve dehydrogenation of ethane (ODHE) has been studied in some detail. it has been found that a Li/Nb/MgO catalyst with 16 wt % niobium showed the highest activity for the C, production in the OCM reaction; the activity at 600 “C was ten times that of the Li/MgO catalyst at the same...

Conversion of methane into higher hydrocarbons is a process of enormous technological importance, which would benefit from a better understanding of the nature of the surface intermediates formed during methane activation. Currently methane is converted into hydrocarbons mainly by an indirect route[1, 2] via syn gas[3] as the intermediate. Alternative routes, such as oxidative coupling of metha...
