    摘要: A method for separating the components of a mixture containing methyl methacrylate, water, and methanol in which the mixture is dehydrated in a first stage membrane unit, producing a dehydrated mixture. Methanol in the dehydrated mixture is removed in a second stage membrane unit, producing a retentate stream containing methyl methacrylate and substantially no said methanol.

    摘要: A mixed matrix membrane including at least one layer of a porous carbon-based structure and a plurality of silicalite crystals dispersed on a surface of the porous carbon-based structure and/or within the porous carbon-based structure. The membrane is suitable for use in processes involving the separation of ethanol from ethanol-containing mixtures.
