Title: Lifeng Wang: Innovator in Zeolite Technology
Introduction
Lifeng Wang is a notable inventor based in Bryn Mawr, PA (US), recognized for his contributions to zeolite technology. He holds 2 patents that focus on advancements in metal-containing chabazite zeolites and their applications in selective catalytic reduction processes.
Latest Patents
Wang's latest patents include the direct synthesis of metal-containing CHA zeolites. This innovation features a metal-containing chabazite zeolite characterized by an FTIR peak area ratio between the peak at 900-1300 cm (Si—O—Si asymmetric stretch) and the peak at 765-845 cm (Si—O—Si symmetric stretch) of at least 55. The method for preparing these zeolites utilizes alkali cation-free reaction mixtures containing three OSDA structures: metal-polyamine, N,N,N-trimethyl-1-adamantyl ammonium (TMAda+), and TMAOH. The resulting metal-containing CHA zeolites can be identified through various techniques, including XRD, FTIR spectroscopy, FT-VIS spectroscopy, and scanning electron microscopy. Additionally, Wang has developed a method for selective catalytic reduction of NOx in exhaust gas using these materials.
Another significant patent involves low-silica chabazite zeolites with high acidity. This microporous crystalline material has a molar silica to alumina ratio (SAR) ranging from 10 to 15, with a fraction of Al in the zeolite framework of 0.63 or greater. The patent also describes a method for the selective catalytic reduction of nitrogen oxides in exhaust gas, which involves contacting exhaust gases with the disclosed microporous crystalline material, typically in the presence of ammonia, urea, or hydrocarbon compounds.
