INFLUENCE OF NOBLE METALS ON THE PERFORMANCE OF Co/SiO_2 CATALYST FOR 1-HEXENE HYDROFORMYLATION

摘要

Small amount of Pt, Pd and Ru promoters in Co/SiO_2 led to great improvement of catalyst activity for hydroformylation of 1-hexene. The 1-hexene conversion as high as 89.7% and oxygenate products selectivity of 88.9% were obtained after 2 h reaction on Pd promoted Co/SiO_2 catalyst. The increasing of reduction degree, the minimizing of cobalt particle size and the enhancement of carbonyl and linear CO adsorption were responsible for the improved performance of the catalyst.
