Her work focuses on improving the properties and applications of ZSM-5 zeolites, which are crucial in various industrial processes.
Latest Patents
One of her latest patents involves the development of ZSM-5 zeolites having uniformly large crystals. This innovation provides an improvement for making large crystallite ZSM-5 zeolites by forming the zeolite in a medium containing a combination of tetramethylammonium and tetrapropylammonium cations. The addition of sodium chloride to the aqueous reaction medium enhances the uniformity of crystallite size and increases the mean crystallite size. Additionally, she has developed catalysts comprising these ZSM-5 crystallites and processes for converting organic compounds using these catalysts. Another notable patent addresses the abatement of nitrogen oxides in industrial exhaust gases. This process involves the reduction of nitrogen oxides with ammonia in the presence of a catalyst that includes a porous crystalline siliceous solid, such as a ZSM-5 type zeolite. The catalyst is designed to respond quickly to changes in NO.sub.x load, utilizing a zeolite of low to moderate acid activity.
