The present invention provides a method for preparing an asphalt and thermoplastic elastomer composition. The process comprises preparing a crosslinking elastomer concentrate that is added to a heated asphalt cut in a stirred tank and then aged to improve SHRP high temperature grading. The crosslinking elastomer concentrate is prepared by adding thermoplastic elastomer and crosslinking agents to a suitable carrier oil, preferably an aromatic oil such as Hydrolene H series. This concentrate is maintained at a temperature that promotes association between the crosslinking agents and the elastomer for a time sufficient for association to substantially complete. In one embodiment, the associating time is in excess of 2 hours up to 24 hours. The asphalt is heated to a temperature sufficient to allow the stirring of the asphalt in the tank. The crosslinking thermoplastic elastomer concentrate is added to the asphalt while continuing to stir the asphalt.

A process is provided for the alkylation of aromatic substrates with a C. sub. 2 -C. sub. 4 alkylating agent over an alkylation catalyst comprising zeolite omega at moderate temperature and pressure conditions to provide liquid phase conditions. The liquid phase alkylation process is carried out using a plurality of series connected reaction stages operated at an average temperature of no more than 300. degree. C. with the interstage injection of the C. sub. 2 -C. sub. 4 alkylating agent in a manner to maintain at least 2 mole percent of alkylating agent solubilized in the aromatic substrate. The reaction stages of a multistage system are operated at a pressure above the vapor pressure of the aromatic substrate and below the vapor pressure of the alkylating agent at the alkylation reaction conditions. The aromatic substrate and the alkylating agent are supplied to a first of the reaction stages in relative amouns to provide a first mole ratio of aromatic substrate to alkylating agent. The effluent from the first reaction zone is supplied to a second reaction stage.

A process for the production of ethylbenzene by the ethylation of benzene in the critical phase over a molecular sieve aromatic alkylation catalyst comprising cerium-promoted zeolite beta. An aromatic feedstock having a benzene content of at least 90 wt. % is supplied into a reaction zone and into contact with the cerium-promoted zeolite beta having a silica/alumina mole ratio within the range of 50-150 and a cerium-aluminum ratio of 0. 5-1. 5. Ethylene is supplied to the alkylation reaction zone in an amount to provide a benzene/ethylene mole ratio of 1-15. The reaction zone is operated at temperature and pressure conditions in which benzene is in the super critical phase to cause ethylation of the benzene in the presence of the cerium zeolite beta alkylation catalyst. An alkylation product is produced containing ethylbenzene as a primary product with the attendant production of heavier alkylated by-products of no more than 60 wt. % of the ethylbenzene.

A process for reducing the amount of undesirable byproducts, for example multi-ring compounds known as heavy residue in a process for the alkylation of an aromatic hydrocarbon with an olefin using a silicalite catalyst is disclosed. The process comprises supplying a feedstock containing benzene to a reaction zone with an alkylating agent in a molar ratio of benzene to alkylating agent of from about 2:1 to about 20:1 and into contact with an aluminosilicate alkylation catalyst having an average crystallite size of less than about 0. 50. mu. m and wherein the size of about 90% of the crystallites is less than 0. 70. mu. m. The catalyst is characterized by an Si/Al atomic ratio in the range from between 50 and 150 and a maximum pore size in the range from about 1000 to 1800. ANG. The catalyst has a sodium content of less than about 50 ppm and the reaction is carried out under conversion conditions including a temperature of from about 250. degree. C. to about 550. degree. C.

A process for the production of ethylbenzene by the alkylation of benzene over a molecular sieve aromatic alkylation catalyst followed by transalkylation of polyalkylated aromatic components and then liquid phase alkylation. A feedstock containing benzene and ethylene is supplied to a first alkylation reaction zone containing a molecular sieve aromatic alkylation catalyst. The reaction zone is operated at temperature and pressure conditions to cause gas phase ethylation of the benzene with the production of an alkylation product comprising a mixture of ethylbenzene and polyalkylated aromatic components including diethylbenzene with xylene present in only small amounts. The output from the alkylation reaction zone is supplied to an intermediate recovery zone for the separation and recovery of ethybenzene, a polyalkylated aromatic compound component including diethylbenzene. At least a portion of the polyalkylated component is supplied along with benzene to a transalkylation reaction zone operated in the liquid phase. Disproportionation product from the transalkylaton reaction zone is supplied to a second alkylation zone containing a molecular sieve aromatic alkylation catalyst.

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.

Ethylbenzene is produced by alkylation over monoclinic silicalite catalysts having a weak acid site concentration of less than 50 micromoles per gram. A feedstock containing benzene and ethylene is applied to an alkylation reaction zone having at least one catalyst bed containing a monoclinic silicalite catalyst having a weak acid site concentration of less than 50 micromoles per gram. The alkylation reaction zone is operated at temperature and pressure conditions in which the benzene is in a gaseous phase to cause gas-phase alkylation of the aromatic substrate in the presence of the silicalite catalysts to produce an alkylation product. The alkylation product is then withdrawn from the reaction zone for separation and recovery.
