    Abstract: An amorphous catalyst support comprising at least a first oxide selected from the group consisting of: silica, germanium oxide, titanium oxide, zirconium oxide or mixtures thereof, preferably silica gel beads or diatomaceous earth; a group 3 metal oxide; and anions in an amount not greater than 10% by weight of the catalyst support; wherein the group 3 metal oxide is incorporated in the first oxide structure at the molecular level. The catalyst support is prepared by (a) mixing the first oxide, with an anhydrous source of the group 3 metal oxide, and water, at a pH above 11, thus forming a suspension, (b) washing the catalyst support with water, (c) separating the catalyst support from the water, and (d) optionally drying and/or calcining the catalyst support. A catalyst based on such a support has improved catalytic properties.

  • Patent number: 8119745
    Abstract: Process for the manufacture of 1,2-dichloroethane (DCE) starting from a stream of ethane which is subjected to a catalytic oxydehydrogenation (ODH) producing a gas mixture containing ethylene then dried and subjected to an absorption to be separated into a fraction enriched with the compounds that are lighter than ethylene containing some of the ethylene conveyed to a chlorination reactor R1 in which most of the ethylene is converted into DCE, and into a fraction F1 which is subjected to a desorption D1 to be separated into an ethylene fraction depleted of the compounds that are lighter than ethylene conveyed to a chlorination reactor R2, the stream of products derived from this reactor being added to the dry gas mixture, and into a fraction F2. Fraction F2 is then subjected to a desorption D2 to be separated into a fraction enriched with ethylene conveyed to an oxychlorination reactor in which most of the ethylene is converted into DCE, and into a fraction F3 which is recycled to the absorption.
