METHOD OF REGENERATION OF PALLADIUM CATALYST Russian patent published in 2008 - IPC B01J23/96 B01J23/44 

FIELD: chemistry.

SUBSTANCE: method of regeneration of the palladium catalyst of the hydrogenation of acetylenic hydrocarbons is described by processing it using an inert gas, then by mixture of an inert gas with an oxygen-containing gas at raised temperature till the content of CO₂ in the outgoing regeneration gas is less than 0,05 % vol., cooling of the catalyst, the subsequent restoration of the catalyst from the oxidized form of palladium up to metal in an atmosphere of hydrogen containing gas and its cooling up to the temperature of the reaction of hydrogenation, and the catalyst after inert-gas flushing, additionally blow hydrogen-containing gas at the temperature 200-250°C and regeneration of the catalyst layer in adiabatic reactor is conducted separately, with a separate supply and outlet of regeneration gas for each catalyst layer.

EFFECT: improvement of restoration of operational characteristics of the palladium catalyst at carrying out the of process of regeneration.
