    摘要： In a process for preparing an alkylaromatic hydrocarbon composition an olefinic hydrocarbon mixture and an aromatic compound are contacted under alkylation conditions with an aromatic alkylation catalyst selected from a homogeneous acid catalyst and heterogeneous acid catalyst comprising a molecular sieve having an X-ray diffraction pattern including d-spacing maxima at 12.4±0.25, 6.9±0.15, 3.57±0.07 and 3.42±0.07 Angstroms. The olefinic hydrocarbon mixture comprises at least 5 wt % by weight of mono-olefin oligomers of the empirical formula: CnH2n wherein n is greater than or equal to 10, the mono-olefin oligomers comprising at least 20 percent by weight of olefins having at least 12 carbon atoms, and the olefins having at least 12 carbon atoms having an average of from 0.8 to 2.0 C1-C3 alkyl branches per carbon chain. Sulfonation of the alkylaromatic hydrocarbon product produces an alkylaryl sulfonate mixture that exhibits advantageous properties, such as biodegradability and hard and cold water performance.

    摘要： A method is described for preparing a molecular sieve-containing catalyst for use in a catalytic process conducted in a stirred tank reactor. The method comprises providing a mixture comprising a molecular sieve crystal and forming the mixture into catalyst particles having an average cross-sectional dimension of between about 0.01 mm and about 3.0 mm. The mixture may include a binder and the catalyst particles are then calcined to remove water therefrom and, after calcination and prior to loading the catalyst particles into a reactor for conducting the catalytic process, the catalyst particles are coated with a paraffin inert to the conditions employed in the catalytic process.
