Latest Patents
Hughes holds a patent for the "Direct synthesis of metal-containing CHA zeolites." This invention describes 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 outlined in the patent allows for the preparation of metal-containing CHA zeolites with high selective catalytic reduction (SCR) activity at low reaction temperatures. The process 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 using various techniques, including XRD, FTIR spectroscopy, FT-VIS spectroscopy, and scanning electron microscopy. Additionally, the patent discloses a method for the selective catalytic reduction of NOx in exhaust gas using the described material.
