Abstract

1455030 Catalyst regeneration BRITISH PETROLEUM CO Ltd 9 April 1975 [25 April 1974] 18121/74 Heading B1E [Also in Division C5] A supported nickel catalyst, e.g. partially sulphided elemental nickel on alumina, silica or sepiolite, which has been deactivated by use for the selective hydrogenation of di-olefins and/or acetylenes in the presence of mono-olefins is regenerated by (i) purging the catalyst of volatile hydrocarbons with an inert gas at 120- 350‹C, (ii) burning off hydrocarbonaceous deposits with an oxygen/inert gas mixture at 350- 450‹C, (iii) initiating the reduction of the resuiting oxidised catalyst with a hydrogen/inert gas mixture at 350-450‹C, and (iv) completing the reduction with hydrogen at 350-450‹C. The inert gas may be steam or nitrogen. The specified regeneration steps may be preceded by washing the catalyst with a hydrocarbon e.g. aromatic, naphthanic or paraffinic, liquid to reduce the hydrocarbonaceous deposits. The burn-off may be conducted in two or more stages at increasing temperatures and may be followed by an inert gas purge.
