measurements have already confirmed the very fast accu-
mulation of oligomers in this reaction (12). Further work is
needed to clarify the mechanism of deposit formation and
to find a model consistent with the amount of deposit and
its effect on the hydrogenation behaviour.

sample as indicated in Fig. 4. The observed values of E
are 48.1 and 51.1 kJmolꢁ1 over fresh sample and Cat. A,
respectively but 25.3 kJmolꢁ1 over Cat. B. The observed
isotope effect of hydrogen addition does not differ from
values published for ethene (23) or acetylene (24) hydro-
genations and it may allow one to suggest that addition of
hydrogen to C4X7 and C3X7 (X = H or D) is the rate limiting
step over Cat. A. Over Cat. B the RH/RD values are smaller
and for propene it is only 1.2. In the absence of further evi-
dence this result may point to some compensation between
kinetic and equilibrium hydrogen isotope effects (23).
To summarize this study, it has been shown that large
amounts of hydrocarbonaceous materials increase the se-
lectivity of complete hydrogenation and exerts a detrimen-
tal effect on the diene–alkene competition for the active

creasing effective diffusivity of acetylene in hydrogenation
of acetylene–ethene mixtures over Pd catalysts provides a
reasonable ground to explain the slowdecrease ofacetylene
