COMPOSICOES DE SILICATO E BOROSSILICATO DE METAL CRISTALINO SINTETICO E SUA PREPARACAO |
摘要 |
Crystalline metal silicates and metal borosilicate compositions exhibit useful catalytic properties when the reaction mixture from which they are prepared includes a metal whose oxide precipitates at a pH above 7 and an amount of urea or other compound which upon hydrolysis releases ammonia. The precipitated metal hydroxide is incorporated into the crystalline composition as it forms. These compositions exhibit the X-ray pattern of a ZSM-5 zeolite and have an aluminum content of less than 100 wppm and a composition expressed in terms of its oxides as follows: < IMG > where R is tetramethyl ammonium cation, ammonium cation, hydrogen cation, an alkali metal cation, metal cation or mixtures thereof, n is the valence of R, M is a metal whose hydroxide precipitates at a pH above 7 and m is the valence of said metal. These crystalline silicates and borosilicates are usefully employed as catalysts in hydrocarbon conversions. |
