PROBLEM TO BE SOLVED: To efficiently obtain carbon monoxide and hydrogen from gas containing methane and carbon dioxide by using a catalyst obtained by carrying a rare earth metal oxide, an alkaline earth metal oxide, nickel and a very small amount of rhodium on a support and firing them....
Molecular catalysts that mediate reactions with carbon dioxide often promote chemical reductions that form either carbon monoxide or formic acid (HCO2H), but lack the activity and selectivity to reduce these compounds further to make other useful products, such as methanol, ethanol or methane. ...
Researchers from Japan and Poland have developed a reactor design that efficiently captures CO2emissions and converts them into usable methane fuel. This breakthrough could significantly reduce greenhouse gas emissions, paving the way for a carbon-neutral future. Credit: Professor Mikihiro Nomura SIT, ...
The first patent application includes the design and manufacture of a new chemical catalyst that turns methane gas and carbon dioxide directly into gasoline.doi:10.1016/s1351-4180(10)70449-9NoneELSEVIERFocus on Catalysts
Various processes can convert CO2to hydrocarbons, but they usually produce volatile single-carbon hydrocarbons such as methane and methanol. Building carbon–carbon bonds to produce longer chain, liquid hydrocarbons is a significant challenge. Recently, however, researchers have shown that zeolites can ...
Capture and convert - this is the motto of carbon dioxide reduction, a process that stops the greenhouse gas before it escapes from chimneys and power plants into the atmosphere and instead turns ...
Biogas is produced when organic material is broken down by means of microorganisms without access to oxygen. The gas mainly consists of methane and carbon dioxide and small amounts of steam, nitrogen, hydrogen sulfide and ammonia. Currently, the gas is used for production of heat and electricity...
In place of a vacuum, the researchers use a stream of fuel such as hydrogen or methane. These materials are so readily oxidized that they will actually draw the oxygen atoms through the membrane without requiring a pressure difference. The membrane also prevents the oxygen from migrating back an...

gas is pumped into some kind of deep underground reservoir or converted to an inert solid such as limestone, another promising avenue has been converting the gas into othercarbon compoundssuch as methane or ethanol, to be used as fuel, or ethylene, which serves as a precursor to useful ...
