  • 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.

  • PROCESS FOR THE SULFOCHLORINATION OF HYDROCARBONS
    Publication number: 20120116121
    Abstract: Produce a sulfo-chlorinated hydrocarbon using liquid sulfur dioxide, a chlorinating agent such as chlorine or sulfuryl chloride, and a metal complex catalyst, the catalyst being represented as LnM where L is at least one of an amine, phosphine, chloride or oxide, n is an integer within a range of from 1 to 6, and M is a metal selected from a group consisting of copper (Cu), ruthenium (Ru), iron (Fe), chromium (Cr), lanthanum (La), nickel (Ni), palladium (Pd), rhodium (Rh), rhenium (Re), molybdenum (Mo) and manganese (Mn).
