The choice of an optimal composition and preparation method of non-promoted Pd/Al2O3 and promoted Pd-Co/Al2O3 catalysts for the selective hydrogenation of vinylacetylene

Selective hydrogenation of mixed C4 containing high vinyl acetylene by Mn-Pd, Ni-Pd and Ag-Pd on Al2O3 catalysts

“…In addition, several transition metals have been added to Pd/Al 2 O 3 to promote the catalytic performances for selective alkyne hydrogenation. Lamberov et al [11] reported testing cobalt promoted Pd/Al 2 O 3 catalysts prepared by a sequential penetration method. The Pd:Co molar ratio on the catalysts was varied from 1:2 to 3:1.…”

“…Currently, this concentrated vinyl acetylene stream is combusted due to safety concerns [7,9]. Therefore, to minimize waste and to recover additional C4 products, selective hydrogenation of vinyl acetylene into more valuable compounds such as 1,3-butadiene and 1-butene has been suggested [10][11][12][13][14][15][16].…”
