Recently, methane has attracted much attention as an alternative carbon feedstock since it is the major component of abundant shale and natural gas. In this work, we produced methanol from methane using whole cells of Methylosinus trichosporium OB3b as the biocatalyst. M. trichosporium OB3b was cultured on NMS medium with a supply of 7:3 air/methane ratio at 30°C. The optimal concentrations of ...

Among the technologies available to reduce methane emitted from the pig industry, biofiltration seems to be an effective and inexpensive solution. In methane (CH4) biofiltration, nitrogen is an important macronutrient for the microorganisms growth. The objective of this research project was to study the effect of ammonium (NH4) on the performance, the biomass production and the nitrogen convers...

Catalytic combustion and conversion of methane are characterized by a complex interaction of transport and chemical reactions on the catalytic surface and in the gas phase. Computational tools have been developed in which the catalytic processes are coupled to the surrounding flow. These tools are applied to study catalytic combustion of methane on platinum and catalytic conversion of methane t...

Utilization of methane to produce chemicals has become attractive due to significantly reduced prices for methane gained from recent development in natural gas recovery. However, the lack of suitable catalysts for methane conversion (other than steam reforming) hinders its advances. While intensive research has been conducted on oxidative methane upgrading over decades, the carbon selectivity a...

We optimized and tested a postbioprocessing step with a single-culture archaeon to upgrade biogas (i.e., increase methane content) from anaerobic digesters via conversion of CO(2) into CH(4) by feeding H(2) gas. We optimized a culture of the thermophilic methanogen Methanothermobacter thermautotrophicus using: (1) a synthetic H(2)/CO(2) mixture; (2) the same mixture with pressurization; (3) a s...

2 Discipline of Chemistry, School of Environmental and Life Sciences, The University of Newcastle, Callaghan, NSW 2308, Australia Abstract: The reaction of a waste refrigerant mixture of CFC-12, HCFC-22 and HFC-134a (in an argon/methane bath gas) in a dielectric barrier discharge non-thermal plasma reactor has been studied. The conversion of the major refrigerant, CFC-12, ranged from 59–76 % fo...

The availability of large reserves of methane, which is the main component of most natural gas, makes it a very important feedstock molecule for the production of base chemicals (e.g. ethylene, propylene, and aromatics) and energy carriers (i.e. transportation fuels). More recently, the shale gas bonanza—particularly in the USA—as well as the presence of vast amounts of gas methane hydrates at ...

The transformation of methane and carbon dioxide by coupling plasma catalysis was investigated using a fluidized bed reactor the results, in terms reactant conversion yields products, were compared with those obtained fixed reactor. A series alumina, including commercial sample various meso-macro materials synthesized laboratory, tested this study. Their surface areas varied from 260 to 312 m2 ...

Methane is abundant and relatively inexpensive, making it an attractive feedstock for producing bulk chemicals. However, the low reactivity of methane makes it difficult to develop commercially viable processes for methane conversion. Because of favorable thermodynamics, many authors have investigated the oxidation and oxidative carbonylation of methane. By contrast, the sulfonation of methane ...

Given our vast methane reserves and the difficulty in transporting methane without substantial leaks, the conversion of methane directly into electricity would be beneficial. Microbial fuel cells harness electrical power from a wide variety of substrates through biological means; however, the greenhouse gas methane has not been used with much success previously as a substrate in microbial fuel ...
