Superior catalytic effect of calcium oxide on the hydrogasification of char for CH4

Superior catalytic effect of calcium oxide on the hydrogasification of char for CH4 •Ca-compounds that decompose to CaO are superior catalysts to hydrogenate char to CH4.•CaO is much more active than the extensively studied catalysts K2CO3 and Ni(NO3)2.•CaO’s activity requires induction that shortens by high temperature and H2 pressure.•CaO’s activity is attributed to break amorphous aromatic C–C bonds.•The induction time is partly attributed to CaO diffusion into the interior of char. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Fuel Elsevier

Abstract

•Ca-compounds that decompose to CaO are superior catalysts to hydrogenate char to CH4.•CaO is much more active than the extensively studied catalysts K2CO3 and Ni(NO3)2.•CaO’s activity requires induction that shortens by high temperature and H2 pressure.•CaO’s activity is attributed to break amorphous aromatic C–C bonds.•The induction time is partly attributed to CaO diffusion into the interior of char.
