Abstract: In a process for the selective disproportionation of toluene to para-xylene, single-pass para-xylene product levels of over 90 % coupled with a toluene conversion of at least 15 % are achieved using a molecular sieve catalyst treated with a silicon-containing compound prior to and/or during at least part of the disproportionation process.

Abstract: A high density polyethylene (HDPE) film is provided having high biaxial orientation. The film includes HDPE having a density of at least 0.940, and a melt index of from 0.5 to 10. The film is stretched in the machine (longitudinal) direction to a degree of from 5:1 to 8:1, preferably from 6:1 to 7:1. The film is also stretched in the transverse (lateral) direction to a degree of from 6:1 to 15:1, preferably from 9:1 to 13:1. Preferably, the film has an orientation imbalance, with a higher degree of transverse orientation than machine orientation. Skin layers such as heat seal layers can be provided. Preferably, the film contains one or more layers of a casting promoter material employed to promote casting of a high gauge HDPE sheet subsequently high biaxially oriented to provide the film. The film can also be cavitated, or otherwise modified (e.g., corona-treated, coated, metallized, etc.) to provide films suitable for special applications. The film of the invention has superior properties, including lower water vapor transmission rate, better dead-fold, higher tensile strength, and consistent gauge profile. Also provided is a method for making the biaxially oriented film.

Abstract: A layered composition of matter, MCM-56, has an X-ray diffraction including the lines listed in Table (II) and has been selectively modified so that the ratio of the number of active acid sites at its external surface to the number of internal active acid sites is greater than that of the unmodified material. When used as an additive to a large pore zeolite catalyst in the catalytic cracking of a petroleum feedstock, the modified MCM-56 gives an improved gasoline yield/octane relationship, an improved coke selectivity and a higher combined gasoline and potential alkylate yield than an identical catalyst containing unmodified MCM-56.

Abstract: The invention relates to a catalyst component which is a contact product of reagents comprising: silica which has a pore volume which exceeds 2.9 cc/gram and an average pore diameter which exceed 400 Angstroms; a metallocene of a first transition metal, activated by an alumoxane; a contact product of dialkylmagnesium and trialkylsilanol; a second transition metal source which exhibits a hydrogen response which is different from that of the metallocene; and an olefin of 4 to 20 carbon atoms. This catalyst component is activated by an aluminum alkyl activator.
