Summary
-
1.
The active surface of a nickel catalyst is not uniform with regard to activation energy of adsorption of acetylene.
-
2.
Hydrogenation of acetylene takes place at certain of the centers which adsorb acetylene reversibly. The centers occupy 4\2–6% of the surface, at the boundary between reversible and irreversible adsorption.
Formation of methane takes place at active centers with higher heats of adsorption. Decomposition of acetylene with liberation of hydrogen takes place at the active centers with the highest heats of adsorption.
-
3.
The non-linear nature of the relation between Eads. and Edes. is established.
