    摘要： Disclosed is a process for the production of alkylated aromatics by contacting a feed stream comprising an alkylatable aromatic, an alkylating agent and trace amounts of water and impurities in the presence of first and second alkylation catalysts wherein the water and impurities are removed in order to improve the cycle length of such alkylation catalysts. Water and a portion of impurities are removed in a dehydration zone. A first alkylation zone having a first alkylation catalyst which, in some embodiments is a large pore molecular sieve, acts to remove a larger portion of impurities, such as nitrogenous and other species, and to alkylate a smaller portion of the alkylatable aromatic compound. A second alkylation zone, which in some embodiments is a medium pore molecular sieve, acts to remove a smaller portion of impurities, and to alkylate a larger portion of the alkylatable aromatic compound.

    摘要： Compositions for reduction of NO X generated during a catalytic cracking process, preferably, a fluid catalytic cracking process, are disclosed. The compositions comprise a fluid catalytic cracking catalyst composition; preferably containing a Y-type zeolite, and a particulate NO X reduction composition containing particles of a zeolite having a pore size ranging from about 3 to about 7.2 Angstoms and a SiO 2 to Al 2 O 3 molar ratio of less than about 500. Preferably, the NO X reduction composition contains NO X reduction zeolite particles bound with an inorganic binder, In the alternative, the NO X reduction zeolite particles are incorporated into the cracking catalyst as an integral component of the catalyst. Compositions in accordance with the invention are very effective for the reduction of NO X emissions released from the regenerator of a fluid catalytic cracking unit operating under FCC process conditions without a substantial change in conversion or yield of cracked products. Processes for the use of the compositions are also disclosed.

    摘要： A process for producing zeolite aggregates involves providing a formable paste composed of zeolite, a binder composed of an organic/metal oxide containing aluminum, a peptizing agent and water; forming the paste into an aggregate, preferably by extruding into an extrudate; curing the aggregate; hydro-thermally calcining the aggregate; and washing the hydro-thermally calcined aggregate with a washing medium, preferably followed by rinsing with a rinsing medium to remove residual washing medium from the aggregate. The washed and rinsed aggregate may then be permitted to equilibrate or is subjected to a drying procedure. Preferably, the washed and rinsed aggregate is again subjected to curing/hydro-thermal calcining. The resultant aggregates, such as extrudates, have an exterior surface with openings and interstitial spaces between particles of binder and zeolite which communicate by such openings between the exterior surface of the aggregate and micropores of the zeolite; the aggregates also exhibit characteristics of crush strength greater than about 0.9 pounds per millimeter and a loss by attrition of less than about 3.0 %. Regenerable catalysts, such as reforming catalysts, based on such aggregate also exhibit a catalyst activity pass through to the zeolite bound in the aggregate of at least 70 % of the initial catalyst activity of freshly prepared zeolite, as well as exhibiting more than about 70 % of the reforming benzene yield that the reforming catalyst exhibited when similarly tested prior to being exposed to a hydrocarbon stream under specified reforming conditions of the catalyst activity test procedures.
