20130272954 | METHOD FOR PREPARING MOLECULAR SIEVE SSZ-87 - This disclosure is directed to a method for preparing a new crystalline molecular sieve designated SSZ-87, which is synthesized using an N,N′-diisopropyl-N,N′-diethylbicyclo[2.2.2]oct-7-ene-2,3:5,6-dipyrrolidinium dication as a structure directing agent. | 10-17-2013 |
20130272955 | MOLECULAR SIEVE SSZ-87 - This disclosure is directed to a new crystalline molecular sieve designated SSZ-87, which is synthesized using an N,N′-diisopropyl-N,N′-diethylbicyclo[2.2.2]oct-7-ene-2,3:5,6-dipyrrolidinium dication as a structure directing agent. | 10-17-2013 |
20140072494 | Treatment of Cold Start Engine Exhaust - The present invention relates to a process for reducing cold start emissions in an exhaust gas stream by contacting the exhaust stream with a combination of molecular sieves comprising (1) a small pore crystalline molecular sieve or mixture of molecular sieves having pores no larger than 8 membered rings selected from the group consisting of SSZ-13, SSZ-16, SSZ-36, SSZ-39, SSZ-50, SSZ-52 and SSZ-73 and (2) a medium-large pore crystalline molecular sieve having pores at least as large as 10 membered rings selected from the group consisting of SSZ-26, SSZ-33, SSZ-64, zeolite Beta, CIT-1, CIT-6 and ITQ-4. | 03-13-2014 |
20140147378 | METHOD FOR PREPARING CHA-TYPE MOLECULAR SIEVES USING COLLOIDAL ALUMINOSILICATE - The present invention is directed to a process for preparing CHA-type molecular sieves using a colloidal aluminosilicate composition containing at least one cyclic nitrogen-containing cation suitable as directing agents for synthesizing CHA-type molecular sieves. | 05-29-2014 |
20140241980 | ZEOLITE SSZ-57 HAVING ENHANCED LARGE PORE SELECTVITY - The present invention is directed to an alumino-borosilicate SSZ-57 zeolite having enhanced large pore selectivity. The alumino-borosilicate SSZ-57 zeolite of the present invention is characterized as having substantially all of its aluminum atoms located within regions of the zeolite structure which form the 12 ring channels. | 08-28-2014 |
20140356280 | Delamination of Borosilicate Layered Zeolite - Provided is a surfactant-free, single-step synthesis of delaminated aluminosilicate zeolites. The process comprises the step of heating a borosilicate zeolite precursor in a metal salt solution, e.g., an aluminum nitrate solution, zinc nitrate solution or manganese nitrate solution. The delaminated aluminosilicate zeolite product is then recovered from the solution. | 12-04-2014 |
20150038322 | ZEOLITE SSZ-70 HAVING ENHANCED EXTERNAL SURFACE AREA - A method is disclosed for preparing zeolite SSZ-70 using an imidazolium cation as a structure directing agent in conjunction with a polyethyleneimine modifier. The SSZ-70 zeolite is characterized as having an external surface area larger than conventional SSZ-70 zeolites. | 02-05-2015 |
