Latest Patents

Baiyan Li holds a patent for "Functionalized porous organic polymers for olefin/paraffin separations." This patent describes compositions that contain a porous organic polymer and a monovalent metal cation, which are designed for the separation and purification of olefins and paraffins. The compositions are noted for their stability and recyclability. They can include acidic functional groups with associated monovalent metal cations, such as Ag(I) and Cu(I), which are capable of strong cation-pi binding to ethylene and other olefins. The compositions boast a large surface area greater than about 20 m²/g and can effectively separate mixtures of ethylene and ethane, achieving an ethylene/ethane adsorption selectivity of about 20 to 500 at 296 K. Methods for synthesizing these compositions include grafting acidic functional groups onto the polymer and cation exchange with a salt or acid of a monovalent metal cation. The methods of olefin/paraffin separation can achieve purities exceeding 99%.
