20130142727 | STABILIZED MICROPOROUS CRYSTALLINE MATERIAL, THE METHOD OF MAKING THE SAME, AND THE USE FOR SELECTIVE CATALYTIC REDUCTION OF NOX - There is disclosed a microporous crystalline material having pore opening ranging from 3 to 5 Angstroms, where the material comprises a first metal chosen from alkali earth group, rare earth group, alkali group, or mixtures thereof, and a second metal chosen from iron, copper or mixtures thereof; and has a molar silica to alumina ratio (SAR) from 3 to 10. The microporous crystalline material disclosed herein may comprise a crystal structure having building units of double-6-rings (d6r) and pore opening of 8-rings as exemplified with framework types defined by the Structure Commission of the International Zeolite Association having structural codes of CHA, LEV, AEI, AFT, AFX, EAB, ERI, KFI, SAT, TSC, and SAV. There is also disclosed a method of selective catalytic reduction of nitrogen oxides in exhaust gas, comprising at least partially contacting the exhaust gases with an article comprising the disclosed microporous crystalline material. | 06-06-2013 |
20140128248 | SMALL CRYSTAL FERRIERITE AND METHOD OF MAKING THE SAME - There is disclosed a highly crystalline, small crystal, ferrierite zeolite prepared from a gel containing a source of silica, alumina, alkali metal and a combination of two templating agents. The resulting material includes ferrierite crystals having a particle size of about or less than about 200 nm. The desired crystal size can be achieved by using a specific composition of the gel. The purity of the material and the crystal size was determined by using X-ray powder diffraction and scanning electron microscopy. The material has excellent surface area and micropore volume as determined by nitrogen adsorption. | 05-08-2014 |
