Sentence examples for methane was formed from inspiring English sources

At low temperatures, a considerable amount of methane was formed through direct hydrogenation of the carbon substrate.

Stable carbon and hydrogen isotope signatures of methane indicated that methane was formed inside the landfill and not in the plume.

Adsorption of CO on Pt/Al2O3 gave an infrared band at 2085 cm−1, and when H2 was adsorbed, methane was formed due to reaction of H2 and the pollutant CO, while increasing the temperature, above 673 K for 1 h or so, when the pollutant CO had almost disappeared during the reaction, a band at 2060 cm−1 appeared due to H2 adsorption on Pt/Al2O3.
