The catalytic selective semihydrogenation of acetylenes using either homogeneous or heterogeneous catalysts has been widely studied in the past several years, because of its academic and industrial interest [1]. The hydrogenation of an alkyne can be virtually stopped at the semihydrogenation stage because the alkyne is more strongly bound than the alkene and competes effectively for the catalytic sites, thus blocking readsorption of the alkene or displacing it. The objective of this paper is to study the influence of the support in the selective hydrogenation of 1-heptyne using Pd(5%)/γ-Al2O3 and Pd(5%)/C.
