  • Heterogeneous catalyst and its use
    Patent number: 8816130
    Abstract: A heterogeneous catalyst that is a combination of rhodium, zinc, iron, a fourth metal and at least one metal selected from alkali metals and alkaline earth metals on a catalyst support (e.g. at least one of silica, alumina, titania, magnesia, zinc aluminate (ZnAl2O4), magnesium aluminate (MgAl2O4), magnesia-modified alumina, zinc oxide-modified alumina, zirconium oxide-modified alumina, and zinc oxide) and use of the catalyst in converting an alkylene to an oxygenate that has one more carbon atom than the alkylene.

  • Heterogeneous catalysts
    Patent number: 8766014
    Abstract: Convert a mixture of synthesis gas and ethylene to a product stream that contains at least one C3 oxygenate using a supported, heterogeneous catalyst represented by formula RhaAgbSncXdYeOx. In the formula, X is at least one transition element other than rhodium or silver, and Y is at least one element selected from alkali metals and alkaline earth metals.
