    Lithium-chloride-promoted sulfated zirconia catalysts for the oxidative dehydrogenation of ethane (1999)

    Notes: Abstract The oxidative dehydrogenation of ethane over sulfated-zirconia-supported lithium chloride catalysts has been systematically investigated. The optimal experimental parameters were obtained. It is found that sulfation of zirconia increases the catalytic activity. 2–3.5 wt% lithium chloride on sulfated zirconia catalysts exhibit high catalytic activity for oxidative dehydrogenation of ethane, with particularly high activity for ethene production. 70% selectivity to ethene at 98% ethane conversion, giving 68% ethene yield, is achieved over 3.5 wt% LiCl/SZ at 650°C.

    Performance of metal‐oxide‐promoted LiCl/sulfated‐zirconia catalysts in the ethane oxidative dehydrogenation into ethene (1999)
    Springer
    Catalysis letters 62 (1999), S. 191-195 
    Details
    ISSN: 1572-879X
    Keywords: sulfated zirconia ; lithium chloride ; metal oxides ; ethane ; oxidative dehydrogenation

    Topics: Chemistry and Pharmacology
    Notes: Abstract The effects of some transition‐ and lanthanide‐metal oxides in LiCl/sulfated‐zirconia (SZ) catalysts on catalytic behavior in the oxidative dehydrogenation of ethane were investigated. It is found that modification of LiCl/SZ by metal oxides significantly improves the catalytic activity and ethene yield. Among those additives, Ni and Nd oxides show the best promoting effect in terms of ethane conversion and ethene yield. 93% ethane conversion with 83% selectivity to ethene has been achieved over the Nd2O3–LiCl/SZ catalyst at 650°C. In addition, those oxide‐promoted LiCl/SZ catalysts are also found to exhibit a longer stability in catalytic performance. Metal‐oxide additives change the chemical structure and surface redox properties, which accounts for the enhancement of activity.

    High-salt solutions prevent reactivation of euglenoid movement in detergent-treated cell models ofEuglena gracilis (1998)
    Springer
    Protoplasma 203 (1998), S. 125-129

    Topics: Biology
    Notes: Summary Detergent-treated cell models ofEuglena gracilis showed rounded-up movement of the cell body upon addition of ATP and Ca2+. Reactivation of the cell models was inhibited when the cell models had been treated with solutions containing 〉150 mM NaCl or 〉300 mM KC1. When the supernatant of salt-extracted cell models was subjected to sodium dodecyl sulfate-polyacrylamide gel electrophoresis, two distinctive bands of 120 and 160 kDa were found to be enriched. The cell membrane and associated cytoskeleton (pellicular complex) were isolated after treatment with salt solutions, and examined by electron microscopy to identify essential cortical structures required for reactivating rounding-up cell movement. Among three regularly arranged microtubules, only one and its associated structures were selectively dissolved from the pellicular strips, while the other pellicular elements remained intact. These structures were located in the groove region where sliding between strips is believed to occur during cell shape change. These results suggest a possible involvement of microtubule 2 and its associated bridges in active sliding between adjacent pellicular strips during euglenoid movement.
