摘要： A process for producing an ethylbenzene product having a purity of at least 99.50 percent based on the weight of ethylbenzene present in the product by the ethylation of the benzene present in non-extracted feed, e.g., non-extracted hydrocarbon composition. The non-extracted feed is substantially free of both C4− hydrocarbons and the C7+ aromatic hydrocarbons and contains benzene and benzene coboilers. The process is carried out in the liquid phase, in the presence of an acid-active catalyst containing MCM-22 family molecular sieve, and under specified conditions.

摘要： Bromine reactive hydrocarbon contaminants are removed from aromatic streams by first providing an aromatic feedstream having a negligible diene level. The feedstream is contacted with an acid active catalyst composition under conditions sufficient to remove mono-olefins. An aromatic stream may be pretreated to remove dienes by contacting the stream with clay, hydrogenation or hydrotreating catalyst under conditions sufficient to substantially remove dienes but not mono-olefins.

摘要： This invention is a process for the upgrading of distillate feeds. A batch of supported hydroprocessing catalyst is placed in a reaction zone, which is usually a fixed bed reactor. The hydroprocessing catalyst comprises an effective amount of a noble metal or metals and has a specific activity. Both low aromatic diesel and jet fuel may be produced in separate blocks over the same catalyst batch, using different feeds and often different conditions. The activity of the catalyst is restored each time the feed is switched. When production is switched from jet fuel to low aromatics diesel, activity may be regained more quickly by holding the catalyst at a higher temperature than the reaction temperature for a specific period of time prior to dropping the temperature to the reaction temperature. Switching from one feed to the other may continue for about one year before the catalyst batch is changed. A dual catalyst system may alternatively be employed. In this case a hydroprocessing catalyst batch comprising an effective amount of at least one base metal is used in combination with the catalyst comprising an effective amount of at least one noble metal catalyst. The feed contacts the catalyst comprising the base metal before it contacts the catalyst comprising a noble metal. In a dual catalyst system, the feeds may be switched for about two years over the two catalyst batches before fresh catalyst is necessary.

摘要： Cell-free extracts from Pyrococcus furiosus were found to possess unusually high levels of proteolytic activity as measured by hydrolysis of azocasein; loss in activity was only 30% after incubation for 24 hours at 98.degree. C. and the half-life of proteolytic activity at that temperature was about 60 hours. Furthermore, cell-free extracts incubated at 98.degree. C. in 1% sodium dodecyl sulfate (SDS) for 24 hours yielded an SDS-resistant protease having a temperature optimum of at least 100.degree. C. The enzyme retained at least 40% of its activity when tested at 98.degree. C. by azocasein hydrolysis in the presence of 4M urea, 2M guanidinium chloride, 10 mM dithiothreitol or 150 mM .beta.-mercaptoethanol. The protease was found to have a pH optimum of 6.8 at 98.degree. C. and retained more than 45% of its activity at pH 9.3 and 82% of its activity at pH 4.5 in assays performed at those values. The protease was classified as a metalloprotease through inhibitor studies, and peptide hydrolysis showed trypsin-like cleavage with additional activities.

摘要： A method is disclosed for the pretreatment of olefinic hydrocarbon feedstock to remove conjugated dienes and/or basic nitrogen compounds that deactivate acidic catalyst particles used in olefin conversion processes by reacting the dienes with one or more dienophiles to form the corresponding Diels-Alder adduct, followed by catalytic conversion of the olefinic hydrocarbon feedstock containing the adduct. The formation of the Diels-Alder adduct essentially eliminates the role of dienes in the feedstock as catalyst deactivating agents. When maleic anhydride (MA) is employed as the dienophile, basic nitrogen reacts with maleic anhydride, or with the tetrahydrophthalic anhydride adduct, to lower the amount of catalyst deactivating basic nitrogen compounds in the feedstock. Where the olefin conversion process comprises etherification of isoolefins with alkanol in a C.sub.4 + or C.sub.5 + olefinic hydrocarbon feedstream to produce a gasoline boiling range product enriched in oxygen and rich in high octane value alkyl tertiary alkyl ethers, it has been discovered that the adduct, particularly those adducts formed with MA, is in the gasoline boiling range and contributes usefully to the oxygen enrichment of the gasoline and to octane value.
