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.

Claim (Index 3):
A process for process for preparing glycols from a saccharide-containing feedstock comprising steps of:\n i) contacting said saccharide-containing feedstock in a solvent and, optionally, hydrogen with a homogeneous retro-aldol catalyst composition in a first reaction zone within a reactor system, to provide an intermediate process stream comprising at least glycolaldehyde and a metallic component in a solvent; ii) passing at least a portion of said intermediate 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; and iii) providing said permeate stream to a second reaction zone within the reactor system and contacting it therein with hydrogen in the presence of a hydrogenation catalyst composition to provide a product stream comprising glycols.
