Conversion of synthesis gas to lower olefins using modified molecular sieves

Abstract From the Canadian patent

The present invention provides a method for incorporating one or more Fischer Tropsch catalysts into molecular sieves comprising contacting untreated molecular sieves with a catalyst precursor in an inert atmosphere under first conditions effective to form complexes comprising said catalyst precursor and said molecular sieves; and, exposing said complexes to an inert atmosphere and to second conditions effective to dissociate volatile components from said catalyst precursor and to evaporate solvent from said complexes forming , modified molecular sieves comprising a catalytically effective amount of a catalyst selected from the group consisting of iron cobalt, nickel, chromium, …
