Mechanism of Cobalt-Catalyzed CO Hydrogenation: 1. Methanation [PDF]

ACS Catalysis, 2017
The mechanism of CO hydrogenation to CH4 at 260 °C on a cobalt catalyst is investigated using steady-state isotopic transient kinetic analysis (SSITKA) and backward and forward chemical transient kinetic analysis (CTKA). The dependence of CH x residence time is determined by 12CO/H2 → 13CO/H2 SSITKA as a function of the CO and H2 partial pressure and ...

Carbon Dioxide Reduction with Hydrogen on Fe, Co Supported Alumina and Carbon Catalysts under Supercritical Conditions

Molecules, 2021
Reduction of CO2 with hydrogen into CO was studied for the first time on alumina-supported Co and Fe catalysts under supercritical conditions with the goal to produce either CO or CH4 as the target products.

Selective CO Production by Photoelectrochemical Methane Oxidation on TiO₂ [PDF]

ACS Central Science, 2018
The inertness of the C-H bond in CH4 poses significant challenges to selective CH4 oxidation, which often proceeds all the way to CO2 once activated. Selective oxidation of CH4 to high-value industrial chemicals such as CO or CH3OH remains a challenge.

Methanation of CO, CO2 and selective methanation of CO, in mixtures of CO and CO2, over ruthenium carbon nanofibers catalysts

Applied Catalysis A: General, 2010
Abstract The catalytic performance of ruthenium catalysts supported on carbon nanofibers for the methanation of CO, CO 2 and their mixture has been investigated with respect to the nature of carbon nanofibers (orientation of graphite planes): platelet, fishbone and ribbon.

CO-tolerant RuNi/TiO2 catalyst for the storage and purification of crude hydrogen

Nature Communications, 2022
Efficient storage of crude hydrogen, through toluene hydrogenation to methylcyclohexane, is often inhibited by CO impurities. Here, the authors develop a RuNi/TiO2 catalyst which avoids deactivation through promoting simultaneous CO methanation.
