Mn Modified Ni/Bsentonite for CO2 Methanation

Pebax-Modified Cellulose Acetate Membrane for CO2/N2 Separation

Carbon dioxide (CO2) release from the exhaust gas streams of power plants that burn fossil fuels contributes the most emission of this gas, which includes more than half of the greenhouse effects. Thus, the separation of CO2 from exhaust gases is one of the main environmental concerns. Membrane technology, due to many advantages, has attracted many research attentions among the various gas sepa...

A Cost Estimation for CO2 Reduction and Reuse by Methanation from Cement Industry Sources in Switzerland

The Swiss government has signed the Paris Climate Agreement and various measures need to be implemented in order to reach the target of a 50% reduction in CO2 emissions in Switzerland by 2030 compared with the value for 1990. Considering the fact that the production of cement in Switzerland accounts around 2.5 million ton for CO2 emissions of which corresponds to roughly 7% of the country’s tot...

Kinetic studies of CO2 methanation over a Ni/γ-Al2O3 catalyst.

The production of methane by reacting CO2 with H2 (CO2 methanation) has the potential for producing synthetic natural gas, which could be exported using the existing infrastructure for the distribution of natural gas. The methanation of CO2 was investigated over a wide range of partial pressures of products and reactants using (i) a gradientless, spinning-basket reactor operated in batch mode a...

Cobalt Catalysts Decorated with Platinum Atoms Supported on Barium Zirconate Provide Enhanced Activity and Selectivity for CO2 Methanation

A perovskite-structured barium zirconate, BaZrO3 (BZ), support is demonstrated to enhance the activity, relative to γ-Al2O3, of Co nanoparticle catalysts decorated with Pt for CO2 methanation. The CO2 methanation reaction may play a central role in both CO2 utilization and energy storage strategies for renewable energy. These catalysts require cooperative hydrogen transport between the supporte...
