Developmants of the catalysts for selective hydrogenation of crotonaldehyde to crotyl alcohol

Advances in the catalysts for selective hydrogenation of crotonaldehyde to crotyl alcohol were reviewed, including active components, carriers, promoters and precursors. It was pointed out that further researches should be focused on polymerstabilized metal nanoclusters catalysts, selective hydrogenation over zeolite and carbon nanotubes, rareearth metal as promoters, study on shapeselective hydrogenation using insitu IR spectrum technique,and development of new base metal catalysts and atmosphericpressure fixedbed continuous hydrogenation processes.
