The microbial oxidation of methane in the atmosphere is performed by methanotrophic bacteria that use methane as a unique source of carbon and energy. The objective of this work consisted of the investigation of the best conditions of methane biodegradation by methanotrophic bacteria Methylosinus trichosporium OB3b that oxidize it to carbon dioxide, and the use of these microorganisms in monito...

A plasma–catalyst hybrid system has been developed for the direct conversion of methane to C2+ hydrocarbons in dielectric barrier discharge (DBD) plasma. TiO2 presented highest yield 11.63% among different materials when integrated with DBD plasma, which made us concentrate on TiO2-based catalyst. It was demonstrated that MnTi catalyst showed best coupling performance 27.29% 150 V applied volta...

A comprehensive 3D coupled mathematical model is developed to study the microwave assisted thermocatalytic decomposition of methane with activated carbon as the catalyst. A simple reaction kinetic model for methane conversion (accounting for catalyst deactivation) is developed from previously published experimental data and coupled with the governing equations for the microwaves, heat transfer,...

Macro-mesoporous alumina, calcined at different temperatures (from 400 to 800 °C), were tested in dry reforming of methane reaction under plasma discharge a fixed deposited power (P = 8 W) with ratio CO2/CH4 2. Besides alumina materials, the one possessing lowest surface area (72 m2 g?1) exhibited highest activity: Methane conversion reaches 31.3 % against 23.4, 22.6 and 26.8 for 400, 600 °C, r...

Anthropogenic greenhouse gas emissions have caused changes to the Earth’s climate, resulting in catastrophic weather events that are becoming more frequent and intense. Developing carbon-neutral processes for CO2 conversion powered by renewable energy is one way of attaining a circular economy, as waste converted new carbon-containing product, without also being created by-product during proces...
