Method of regeneration of acetylide-contg. catalyst

摘要

Cu acetylide-contg. catalyst is passed continuous or in batches, in suspended form into a regeneration reactor under a N or air atmos. at least 200-300 deg C, sufficient catalyst being supplied so that the reactor temp. does not exceed a max. temp. between 300 and 600 deg C. C-contg. material is burnt off by addn. of air with addn. of N, Ar, flue gas or steam, as required. The catalyst is discharged from the reactor in the regenerated state.
