Latest Patents
One of Lei Hong's latest patents is titled "Di-substituted siloxane solvents for gas capture." This patent presents a method for separating a gas constituent from a gaseous mixture. The disclosure introduces polyethylene glycol disubstituted siloxane-based solvents that can be utilized in this method. These solvents are particularly useful for pre-combustion CO2 capture and can replace traditional glycol-based solvents while operating at higher temperature ranges. Additionally, they are applicable in generating hydrogen from reformed natural gas or syngas, adjusting CO/H2 ratios for coal and biomass to liquids, and removing CO2 from syngas for coal and biomass to nitrogen fertilizer.
Another significant patent by Lei Hong is the "Method of fabrication of supported liquid membranes." This patent outlines a method for creating a supported liquid membrane that consists of a dense layer in contact with a porous layer, along with a membrane liquid layer within the interconnected pores of the porous layer. The dense layer is made from a solidified material with an average pore size of less than or equal to about 0.1 nanometer, while the porous layer contains interconnected pores with an average pore size greater than 10 nanometers. The fabrication process involves preparing a casting solution of a membrane liquid and a volatile solvent, establishing a pressure difference across the layers, and applying the casting solution to the porous layer.
