  • Metal containing small pore molecular sieve catalyst for oxygenates conversion
    Publication number: 20040048734
    Abstract: A molecular sieve and a molecular sieve catalyst containing a surface heat impregnated with a metal. The molecular sieve is heated in the presence of a metal containing solution at a temperature between 30° C. and 400° C. then separated from the metal containing solution. The molecular sieve and molecular sieve catalyst is used to make olefin from an oxygenate feedstock.
    Type: Application
    Filed: September 15, 2003
    Publication date: March 11, 2004
