Catalytic decomposition of methane over a wood char concurrently activated by a pyrolysis gas

Pyrolysis of glycerol over activated carbons for syngas production

“…This can be attributed to the catalytic effect of the activated carbons on the decomposition of C x H y hydrocarbons (mainly CH 4 ) produced during the pyrolysis. In fact, the use of different carbon materials, including activated carbons, as catalysts of the methane decomposition reaction has been reported previously [45,46]. The catalytic effect is attributed to the active centers located on the carbon surface.…”

Kinetic modelling of char gasification by accounting for the evolution of the reactive surface area

“…Multi-step mechanisms involving the formation of surface moieties (Campbell and Mitchell, 2008;Dufour et al, 2015Dufour et al, , 2008Geier et al, 2013;Hurt and Calo, 2001;Radovic, 2009) are not considered in the present work. In the following the modelling approach will be mainly applied to char gasification by H 2 O and CO 2 .…”

Methane Conversion Assisted by Plasma or Electric Field

“…Testing of various carbon-based catalysts found that amorphous carbon such as active carbon and carbon black exhibited higher activity than ordered catalysts such as graphite and diamond powder 24) . Furthermore, conversion of methane as high as 70 % can be achieved over a wood char catalyst 25) . In the above-described systems using a carbon-based catalyst, the methane decomposition activity might be affected by the oxidized surface at the initial stage and by the pore distribution in the steady state stage before poreplugging 26) .…”
