    Abstract: It has been discovered that divalent metal oxides other than zinc oxide (ZnO) perform equivalently as activators in preparing asphalt polymer compositions. Typically, the crosslinker in these compositions is sulfur. Divalent metal oxides such as cupric oxide (CuO), magnesium oxide (MgO), and calcium oxide (CaO) provide alternative activators to give versatility to designing asphalt polymer compositions. In addition, some of these alternative divalent metal oxides are less expensive than the traditionally used ZnO.

    Abstract: Processes for the conversion of an aromatic substrate over a mordenite catalyst modified by the inclusion of nickel and a second Group 10 metal selected from palladium, platinum and mixtures thereof. A feedstock containing at least one aromatic compound is brought into contact with the catalyst under conditions effective for the conversion of the aromatic compound to at least one derivative product. The resulting reaction product is then removed from the modified mordenite catalyst. The conversion reaction includes a toluene disproportionation reaction in which the feedstock contains toluene and the product recovered from the catalyst contains benzene and xylene. The conversion reaction can also involve a transalkylation reaction in which a mixture of benzene and xylene is brought into contact with the nickel and palladium-modified mordenite to produce a product which contains a monoalkyl benzene. The conversion can also involve the methylation of benzene to produce toluene or the methylation of toluene to produce xylene. The modified mordenite catalyst may contain nickel in an amount greater than the amount of platinum or palladium in the catalyst.

    Abstract: In methods of preparing asphalt including asphalt/elastomeric polymer compositions, it has been discovered that the emission or evolution of H2S can be reduced by adding certain H2S scavengers to the asphalt mixture, but that not every known H2S scavenger can be effective in this method. Particularly helpful H2S scavengers include inorganic metal salts. Suitable inorganic or organic metal salt H2S scavengers include, but are not necessarily limited to those where the metal of the salt is zinc, cadmium, mercury, copper, silver, nickel, platinum, iron, or magnesium, and mixtures of these salts.
