WebApr 1, 2013 · Table 1 shows the catalytic performance of multi-CNTs, graphite and activated carbon in the B–V reaction. Without the use of any catalyst in a blank experiment, cyclohexanone conversion was 5.4% after a reaction time of 4 h. Carbon materials are active for the oxidation of cyclohexanone. WebAs mentioned earlier, atomic hydrogen reacts with graphite even at room temperature and this would result in gasification of the carbonaceous solids; a reaction that would produce hydrocarbon products. Since these later gases were not found is an indication that hydrogen was not dissociated and subsequently bonded to the structure.

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.
