FIELD: chemistry.
SUBSTANCE: invention relates to sandwich catalysts for hydrogenation of acetylene to ethylene. Said sandwich catalyst has inner core containing inert material and outer layer coupled therewith. Note here that said outer layer contains metal oxide, first metal deposited on outer layer and selected from IUPAC table VIII-X-group metals and second metal deposited on outer layer and selected from XI- or XIV-group metal of said table. Note here that said catalyst features availability factor of 3 to 500.
EFFECT: higher catalyst activity, lower catalyst deactivation.
