Abstract
Green-oil accumulation during the selective hydrogenation of acetylene was measured on titania-supported and unsupported catalyst, and changes in the selectivity for ethylene formation with green-oil accumulation were observed. Selectivity decrease was observed on the titania-supported catalyst where green-oil accumulated continuously after induction time, while the green-oil accumulation on the unsupported catalyst resulted in a slight increase in selectivity.
