Off-site regeneration of solid catalysts

摘要

Process for off-site regeneration of a solid catalyst, comprises: (a) washing the catalyst by using one or more fluid in the supercritical state by extracting from the catalyst at least a part of the hydrocarbons present on the surface of the catalyst; and (b) combustion of at least a part of the coke present on the surface of the catalyst, by heat treatment of the catalyst in the presence of oxygen and at a temperature of 300-600[deg] C.
