    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.

    Abstract: Disclosed is an improvement in a process of preparing cyclohexenyl and alkenyl aromatic compounds, such as styrene, that enables economical and convenient removal of nitrogen compounds. The nitrogen compounds can be stabilizers or neutralizers or derived from stabilizers or neutralizers added to prevent styrene homopolymerization. The nitrogen compounds are removed from, in the case of styrene production, the benzene fraction that results from dehydrogenation of ethylbenzene. Because of the preferential solubility of nitrogen compounds in water, a majority of such compounds can be removed by intimately contacting the benzene fraction with sufficient water, at an appropriate point in the process, and then removing most or all of the water with the entrained nitrogen compounds.

    Abstract: A process for the regeneration of a deactivated zeolite beta catalyst such as rare earth promoted zeolite beta catalyst deactivated in the course of an aromatic alkylation reaction. A zeolite beta conversion catalyst deactivated with the deposition of coke is heated to a temperature in excess of 300° C. in an oxygen-free environment. An oxidative regeneration gas is supplied to the catalyst bed with oxidation of a portion of a relatively porous coke component to produce an exotherm moving through the catalyst bed. At least one of the temperature and oxygen content of the gas is progressively increased to oxidize a porous component of the coke. Regeneration gas is supplied having at least one of an increased oxygen content or increased temperature to oxidize a less porous refractory component of the coke. The regeneration process is completed by passing an inert gas through the catalyst bed at a reduced temperature.
