Graphite hydrogen reaction
WebThe reaction between graphite powder and hydrogen peroxide h2o2 cause bubbling and seemed to make the graphite exfoliate some. Can someone please explain what is happening here ? 3 3 3 comments Best Add a Comment 7ieben_ • 21 days ago You know that H2O2 is a strong oxidant. Methanation is an important step in the creation of synthetic or substitute natural gas (SNG). Coal or wood undergo gasification which creates a producer gas that must undergo methaneation in order to produce a usable gas that just needs to undergo a final purification step. The first commercial synthetic gas plant opened in 1984 and is the Great Plains Synfuels plant in Beulah, North Dakota. As of 2016, it is still operational and produces 1500 MW worth of SNG us…
