    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： An oligomerization process in which hydrocarbon feedstocks are contacted with a hydrotreating catalyst in the absence of hydrogen and in the liquid phase. The catalyst is a heterogeneous catalyst selected from supported reduced metals, metals oxides, metal sulfides and combinations thereof. Preferred catalysts include mixed nickel and molybdenum oxides or mixed cobalt and molybdenum oxides. The process also oligomerizes sulfur compounds so that sulfur containing feedstocks can be treated without deactivating the catalysts.

    摘要： It has been found that Pyrococcus furiosus produces several starch hydrolyzing enzymes, both extracellularly and intracellularly, which retain their activity for several hours at or above 100° C. These comprise an &agr;-glucosidase, which has been highly purified, and amylolytic enzymes including an amylase and a pullulanase. In addition, at least one thermostable enzyme activity from P. furiosus that is useful in the process of degradation of cellulose to D-glucose has also been found, namely a &bgr;-glucosidase, which is also active up to at least 95° C.
