Abstract
Disclosed are certain catalysts and catalyst support materials and processes for the preparation of the catalyst support materials and for the selective hydrogenation of 3,4-epoxy-1-butene (EpB) to 1,2-epoxy-butane (butylene oxide--BO). The catalyst support materials have micropores filled with one or more inorganic oxides and the supported catalysts comprise one or more Group VIII metals deposited on the support materials. The rhodium-containing supported catalysts are especially useful for the selective hydrogenation of EpB to BO.
