LOW TEMPERATURE METHANATION OF CO2 OVER AN AMORPHOUS COBALT-BASED CATALYST

Redazione
(AGENPARL) – LONDON (UNITED KINGDOM), ven 15 gennaio 2021 CO2 methanation is an important reaction in CO2 valorization. Because of the high kinetic barriers, the reaction usually needs to proceed at higher temperature (>300 oC). High-efficiency CO2 methanation at low temperature (<200 oC) is an interesting topic, and only several......
