Methane emissions from cattle.

Journal of Animal Science, 1995
Increasing atmospheric concentrations of methane have led scientists to examine its sources of origin. Ruminant livestock can produce 250 to 500 L of methane per day.

Direct Conversion of Methane to Value-Added Chemicals over Heterogeneous Catalysts: Challenges and Prospects.

Chemical Reviews, 2017
The quest for an efficient process to convert methane efficiently to fuels and high value-added chemicals such as olefins and aromatics is motivated by their increasing demands and recently discovered large reserves and resources of methane.

Selective anaerobic oxidation of methane enables direct synthesis of methanol

Science, 2017
A two-step protocol oxidizes methane to methanol using a copper zeolite that is reoxidized by water. A watery route from methane to methanol Methanol production is an expensive, energy-intensive process that initially overoxidizes methane to carbon ...

The Direct Catalytic Oxidation of Methane to Methanol-A Critical Assessment.

Angewandte Chemie, 2017
Despite the large number of disparate approaches for the direct selective partial oxidation of methane, none of them has translated into an industrial process.

Polyvinyl Chloride Microplastics Affect Methane Production from the Anaerobic Digestion of Waste Activated Sludge through Leaching Toxic Bisphenol-A.

Environmental Science and Technology, 2019
The retention of polyvinyl chloride (PVC) microplastics in sewage sludge during wastewater treatment raises concerns. However, the effects of PVC microplastics on methane production from anaerobic digestion of waste activated sludge (WAS) have never been

Efficient methane electrosynthesis enabled by tuning local CO2 availability.

Journal of the American Chemical Society, 2020
The electroreduction of carbon dioxide (CO2RR) to valuable chemicals is a promising avenue to store intermittent renewable electricity. Renewable methane - obtained via CO2RR using renewable electricity as energy input - has the potential to serve as a ...

Storage of hydrogen, methane, and carbon dioxide in highly porous covalent organic frameworks for clean energy applications.

Journal of the American Chemical Society, 2009
Dihydrogen, methane, and carbon dioxide isotherm measurements were performed at 1-85 bar and 77-298 K on the evacuated forms of seven porous covalent organic frameworks (COFs). The uptake behavior and capacity of the COFs is best described by classifying

Methane steam reforming, methanation and water‐gas shift: I. Intrinsic kinetics

, 1989
Intrinsic rate equations were derived for the steam reforming of methane, accompanied by water-gas shift on a Ni/MgAl2O4 catalyst. A large number of detailed reaction mechanisms were considered.
