Latest Patents

Seon-Ju Lim's latest patents include two notable inventions. The first patent, titled "Hierarchical zeolites and preparation method therefor," describes a method for preparing hierarchical zeolites. This method involves several steps, including the preparation of a first mixture solution with a structure-directing agent, an alumina precursor, and a pH controller. The process continues with the injection of a silica precursor into the first mixture, followed by the addition of an aqueous solution containing a surfactant. The final steps include drying and heat-treating the third mixture solution. This invention allows for the creation of hierarchical zeolites with a uniform morphology, resulting in improved activity.

The second patent, "Hierarchical EU-2 type zeolite having both micropores and mesopores, and preparation method therefor," outlines a method for preparing hierarchical zeolite. This method involves a reaction of a mixture containing water, a silica precursor, an alumina precursor, a pH adjustment material, and at least one structure-inducing material along with a surfactant. The drying and heat treatment steps follow the reaction. This innovative approach results in zeolites that possess both micropores and mesopores, enhancing their functional properties.
