    摘要： The present invention provides a method for preparing an asphalt and thermoplastic elastomer composition. The process comprises heating an asphalt cut in a stirred tank to a temperature sufficient to allow the stirring of the asphalt in the tank. A thermoplastic elastomer or rubber is added to the asphalt while continuing to stir the asphalt. The mixture is stirred at a speed and for a period of time sufficient to increase the distribution of the elastomer into the asphalt. The stirring speed is reduced and the temperature is increased to add an oil dispersion or aqueous emulsion of crosslinking agents to the tank. Stirring is continued for a period of time sufficient to improve the distribution of the crosslinking agent dispersion in the asphalt.

    摘要： Process for the production of ethylbenzene by alkylation over a silicalite alkylation catalyst with the subsequent transalkylation of diethylbenzene with the alkylation catalyst and conditions selected to retard xylene production and also heavies production. A feedstock containing benzene and ethylene is applied to a multi-stage alkylation reaction zone having a plurality of series-connected catalyst beds containing a pentasil molecular sieve alkylation catalyst which is silicalite of a predominantly monoclinic symmetry having a silica/alumina ratio of at least 275. The feedstock is supplied to the alkylation reaction zone to cause gas-phase ethylation of benzene at a flow rate to provide a space velocity of benzene over the catalyst to produce a xylene concentration in the product of about 600 ppm or less based upon the ethylbenzene content. Periodically the space velocity may be increased to a value which is greater than the space velocity associated with a minimum concentration of diethylbenzene in the alkylation product such that diethylbenzene production is enhanced while minimizing any attendant transalkylation reactions within the alkylation reaction zone. This is accompanied by a relatively low xylene content in the product, specifically no more than 600 ppm based upon the ethylbenzene in the product. The output from the alkylation reactor is applied to an intermediate recovery zone for the separation and recovery of ethylbenzene with the recovery of a polyalkylated aromatic component which is supplied along with benzene to a transalkylation reaction zone where the polyalkylated aromatic fraction is subject to disproportionation to provide a reduced diethylbenzene content and an enhanced ethylbenzene content. A specific monoclinic silicalite alkylation catalyst has a silica/alumina ratio of at least 300 and has a crystal size of less than one micron.

    摘要： A process for the transalkylation of an aromatic feedstock containing a benzene component and a polyalkylated aromatic component comprising at least one polyalkyl aromatic compound of at least nine carbon atoms. The feedstock is supplied to a reaction zone containing a metal modified zeolite transalkylation catalyst. In one alternative, the process comprises (a) providing a catalytic reaction zone containing a metal modified zeolite transalkylation catalyst; (b) supplying a toluene-containing feedstock to said reaction zone while operating said reaction zone under conditions effective for the disproportionation of toluene; (c) recovering a disproportionation product containing benzene and xylene from said reaction zone; (d) terminating the supply of said toluene-containing feedstock to said reaction zone; (e) thereafter supplying to said reaction zone containing said metal-modified zeolite catalyst a transalkylation feedstock containing a benzene component and a polyalkylated aromatic component comprising at least one polyalkyl aromatic compound having at least nine carbon atoms; (f) operating said reaction zone under conditions effective for the transalkylation of said feedstock to produce a transalkylated product having a reduced polyalkyl benzene content and an enhanced monoalkyl benzene content relative to said transalkylation feedstock; and (g) recovering said transalkylated product from said reaction zone. In another alternative, the reaction zone is operated under conditions providing an equivalent conversion of pure toluene in the presence of the catalyst within the range of 40-55%, resulting in a transalkylated product with a reduced polyalkyl benzene content and an enhance monoalkyl benzene content relative to the transalkylation feedstock. In continued operation of the transalkylation reaction zone, at least one of the reaction conditions of temperature, pressure, and space velocity is adjusted in order to maintain a constant reaction severity to provide a desired equivalent conversion of toluene within a tolerance range of ± 2%. Specifically, the temperature is progressively increased while continuing the operation of the transalkylation zone to maintain a condition of constant reaction severity.

    摘要： The alkylation of benzene-containing feedstock over a zeolite beta alkylation catalyst which is formulated with a silica binder and has an average regeneration coefficient of at least 95% for at least three regenerations. The alkylation reaction is carried out in the liquid phase or supercritical region with a C 2 -C 4 alkylating agent, specifically ethylene. The catalyst exhibits a regeneration coefficient of at least 95% after ethylation of the benzene with ethylene at a benzene/ethylene mole ratio of less than 10. The ethylation of benzene occurs at an initial designated primary activity. The operation of the reaction zone is continued until the activity of the catalyst for the ethylation of benzene decreases by a value of at least 0.1% and not more 1% from the initial designated primary activity. The operation of the reaction for alkylation is terminated and a regeneration procedure is instituted in which the catalyst is regenerated in an oxidizing environment at an average temperature of no more than 500°C. At the conclusion of the regeneration procedure, the operation of the alkylation zone is reinstituted with the reaction zone again operated under conditions as described above followed by regeneration.

    摘要： A method is provided for conversion of heavy alkylaromatic compounds, particularly those in the C 8 - C 12 range, into more valuable aromatics of benzene, toluene and xylene utilizing a toluene disproportionation unit containing a nickel, palladium or platinum-modified mordenite catalyst. The method allows large amounts of these heavy alkylaromatic compounds to be processed without adversely affecting catalyst activity or catalyst life. This is accomplished by introducing the heavy alkylaromatic compounds into the reactor at constant reaction severity conditions and maintaining those conditions during conversion.
