Viscous copper-containing catalyst waste is split up into solid particles and gaseous dichlorobutene along a steadily curved flow path, the liquid film flowing along an inner tube wall being driven along by the gas flowing at a higher rate in the core.

Process for drying copper containing catalyst waste

Improved working up of the waste from an isomerization reaction of dichlorobutene by precipitating the copper catalyst used in said process by adding a polar solvent and removing the resulting precipitate by filtration.
