Latest Patents

One of his latest patents is titled "Titania composite membrane for water/alcohol separation, and preparation thereof." This invention relates to a titania composite membrane designed for separating water/alcohol mixtures. The method involves modifying the surface of a porous support with silica xerogel and γ-alumina sol, followed by coating it with titania sol. The resulting titania surface layer is dried and calcined to enhance separation performance and thermal stability. This membrane exhibits excellent properties, including thermal stability, mechanical strength, and good perm-selectivity for water molecules, making it highly applicable for water/alcohol separation.

Another notable patent is "Preparation of composite silica membranes with thermal stability by a soaking-rolling method." This invention describes a method for creating a composite silica membrane with improved thermal stability. The process involves rolling the surface of a porous support with silica xerogel, soaking it with γ-alumina, and then coating, drying, and sintering the surface. This results in a fine coating membrane that enhances the thermal stability of the porous support.
