摘要: Described are compositions and catalytic articles comprising both a first molecular sieve promoted with copper and a second molecular sieve promoted with iron, the first and second molecular sieves having a d6r unit and the first molecular sieves having cubic shaped crystals with an average crystal size of about 0.5 to about 2 microns. The weight ratio of the copper-promoted molecular sieve to the iron-promoted molecular sieve can be about 1:1 to about 4:1. The catalytic articles are useful in methods and systems to catalyze the reduction of nitrogen oxides in the presence of a reductant.

摘要: A new crystalline aluminosilicate zeolite comprising a MTT framework has been synthesized that has been designated UZM-55. This zeolite is represented by the empirical formula: M+mRrAl1-xExSiyOz where M represents a metal or metals selected from zinc or Group 1 (IUPAC 1), Group 2 (IUPAC 2), Group 3 (IUPAC 3) or the lanthanide series of the periodic table including sodium, potassium or a combination of sodium and potassium cations, R is an organic structure directing agent or agents derived from reactants R1 and R2 such as where R1 is diisopropanolamine and R2 is a chelating diamine, and E is an element selected from the group consisting of gallium, iron, boron and mixtures thereof. Catalysts made from UZM-55 have utility in various hydrocarbon conversion reactions.

摘要: The present invention is directed to the synthesis of novel delaminated layered zeolite precursor materials prepared by fluoride/chloride anion-promoted exfoliation. The method comprises, for example, using a combination of fluoride and chloride anions at a mild pH in aqueous solution to affect delamination of a layered zeolite precursor. The method can also comprise using a combination of fluoride and chloride anions in a non-aqueous solution comprising an organic solvent. The method may be used in conjunction with either acidification or sonication, or both. The resulting delaminated zeolite precursors are then isolated. Precursors that are then isolated lack amorphous silica content. The UCB-1 product is an example of such a novel oxide material and is obtained in yields in excess of 90% without the need for sonication.
