    Abstract: A process for converting hydrocarbons by contacting a hydrocarbon feedstream under hydrocarbon conversion conditions with a large crystal zeolite catalyst. The large crystal zeolite of the catalyst used in the hydrocarbon conversion process is made by heating an aqueous zeolite synthesis mixture under agitation to a temperature equal to or less than the effective nucleation temperature of the synthesis mixture. After this step, the aqueous synthesis mixture is heated in the absence of agitation to a temperature equal to or greater than the effective nucleation temperature of the aqueous zeolite synthesis mixture. The process finds particular application in hydrocarbon conversion processes where reduced non-selective acidity is important for reaction selectivity and/or the maintenance of catalyst activity, e.g., toluene disproportionation, dealkylation, alkylation, and transalkylation.

    Abstract: A process for upgrading petroleum feedstocks boiling in the distillate plus range, which feedstocks, when cracked, result in unexpected high yields of olefins. The feedstock is hydroprocessed in at least one reaction zone countercurrent to the flow of a hydrogen-containing treat gas. The hydroprocessed feedstock is then subjected to thermal cracking in a steam cracker or to catalytic cracking in a fluid catalytic cracking process. The resulting product slate will contain an increase in olefins compared with the same feedstock, but processed in by a conventional co-current hydroprocessing process.

    Abstract: Films, made of polyethylenes and fillers, and articles made therefrom greater WVTR than previously available films based on conventional Zeigler-Natta based polyethylenes. The polyethylenes are produced in a metallocene-catalyzed production process. The films may be made by a cast film process, and may be made in widely varying filler content, generally polyethylene to filler ratios of 30/70 to 70/30. The metallocene based polyethylenes when combined with filler also permit the extrusion of thinner films leading to lighter weight and softer films. The m-polyethylenes utilized for making such films typically have a Composition Distribution Breadth Index above 50 %, an Mw/Mn below 3, and an Mz/Mw below 2. The films may be used advantageously in composite structures with fabrics (either woven or non-woven) to fabricate such articles as house-wrap.

    Abstract: Polar monomer-containing copolymers derived from at least one alpha , beta unsaturated carbonyl compound, such as alkyl acrylates and one or more olefins, such olefins including ethylene and C3-C20 alpha -olefins such as propylene and 1-butene, which copolymers have (a) an average ethylene sequence length, ESL, of from about 1.0 to less than about 3.0; (b) an average of at least 5 branches per 100 carbon atoms of the copolymer chains comprising the copolymer; (c) at least about 50 % of said branches being methyl and/or ethyl branches; (d) substantially all of said incorporated polar monomer is present at the terminal position of said branches; (e) at least about 30 % of said copolymer chains terminated with a vinyl or vinylene group; (f) a number average molecular weight, Mn, of from about 300 to about 15,000 when the copolymer is intended for dispersant or wax crystal modifier uses and up to about 500,000 where intended for viscosity modifier uses; and (g) substantial solubility in hydrocarbon and/or synthetic base oil. The copolymers are produced using late-transition-metal catalyst systems and, as an olefin monomer source other than ethylene preferably inexpensive, highly dilute refinery or steam cracker feed streams that have undergone only limited clean-up steps. Fuel and lubricating oil additives, particularly dispersants, wax crystal modifiers and flow improvers, are produced. Where functionalization and derivatization of these copolymers are required for such additives it is facilitated by the olefinic structures available in the copolymer chains.
