EFFECTS OF VARIOUS PRETREATMENTS OF THE Rh-Y ZEOLITE ON THE CATALYTIC ACTIVITY FOR ETHYLENE HYDROFORMYLATION UNDER ATMOSPHERIC PRESSURE

Article abstract of DOI:10.1246/cl.1983.945

The active species for ethylene hydroformylation formed in the Y zeolite are extremely stable under the reaction conditions and the steady activity lasts more than one month.The catalytic activity is remarkably affected by the pretreatment of the catalyst; the He-H2 pretreatment at 338-453 K enhances the activity while the He-CO or He-CO-C2H4 pretreatment at 400 K reduces it.
