Abstract: The invention provides a process for recovering a metallic component from a process stream, said process comprising passing said process stream over a ceramic membrane comprising a selective layer with a pore size in the range of from at least 0.5 nm to at most 10 nm; applying a pressure difference across said ceramic membrane such that the pressure outside the ceramic membrane is at least 50 kPa lower than the pressure inside the ceramic membrane; and, thus, providing a permeate stream which has passed through the ceramic membrane and which is depleted in the metallic component and a retentate stream enriched in the metallic component; wherein the process stream is derived from a process for the conversion of saccharide-containing feedstock into glycols.
