To gain some insight into the thermodynamic aspects of CH4 formation by the
reaction between elementary carbon and hydrogen-bearing species, the react
ions, (1) non-graphitic carbon + a stream of NH3, (2) non-graphitic carbon
+ a stream of H-2 and (3) graphite + a stream of NH3 were carried out at 90
0 degrees C. (C) 1998 Elsevier Science B.V. All rights reserved.
