Carbon dioxide reforming of methane to synthesis gas was studied employing Ni/La2O3 catalysts. It was found that, in contrast to the performance of other nickel-based catalysts (e.g. Ni/Al2O3 and Ni/CaO) which exhibit continuous deactivation with time on stream, the rate over the Ni/La...
Carbon dioxide reforming of methane to synthesis gas has been investigated over supported Ni catalysts in the temperature range of 500–850°C. Addition of CaO (10mol%) promoter to the Ni/γ-Al2O3 resulted in an increase of reaction rate and an improvement of catalyst stability, which may ...
In recent years, methane has become increasingly abundant due to the development of shale gas fields and other cost efficient or renewable feedstocks such as biogas. Methane is also considered as one of the greenhouse gases with a global warming potential 50 times higher than carbon dioxide1. Met...
INCREASING concern about world dependence on petroleum oil has generated interest in the more efficient use of natural gas1–4. The conversion of methane to the common feedstock synthesis gas (carbon monoxide and hydrogen) by steam reforming is already well established5, and we have shown recently...
Seagrass ecosystems are important carbon dioxide sinks that can sequester carbon for centuries as organic matter in sediment. They are also a major source of methane, a potent greenhouse gas, which limits their carbon sink capacity. However, data are lac
Methane, an economical and clean alternative to fuels, is widely used in power plants and new energy vehicles. However, the emission of the unburned methane will cause the serious greenhouse effect, which is approximately 25 times higher than carbon dioxide [1]. The catalytic combustion technology...

To make methane, hydrogen has to be produced via water electrolysis before being mixed with carbon dioxide, but combining these two processes yields an overall efficiency of between 50 and 60%, with nearly half of the input energy lost as heat, says Yakabe....
The device is a sort of solar panel studded with nanoparticles of copper and iron. It can use the sun's energy or an electrical current to break down the carbon dioxide and water. The base layer is a silicon wafer, topped with nanowires, each 300 nanometers tall and about 30 nanometers...
The world needs a deal duringCOP28to limit a nasty source of emission 温室气体 各国需在COP28大会期间达成协议以规范令人厌恶的排放源 METHANE IS A potent greenhouse gas. Over 20 years it has over 80 times the planet-cooking power of carbon dioxide, and is the culprit behind nearly 45% of ...
