    The yields and selectivities in both the catalyzed and non-catalyzed oxidative dehydrogenation of propane were found to increase with increasing pressure. The results showed that the maximum yields of valuable ODH products could be obtained by adjusting only reactants' partial pressure, while keeping their ratio constant.

    Dehydrogenation – Biological
    Encyclopedia of Catalysis (2002)

    Abstract Dehydrogenation plays a very important role in both nature and human civilization. In chemical industry, dehydrogenations are used to produce propene, butene, butadiene, isobutene, and isopropene from the corresponding alkanes. In living organisms (both animals and plants), respiration is actually a process of oxidation wherein some steps involve dehydrogenation. Almost all dehydrogenation reactions require a catalyst. Catalysts for dehydrogenation can be classified into two main categories: conventional catalysts (including inorganic and organic) and enzymes. This article focuses on the application of biological catalysts in dehydrogenation and oxidation reactions occurring in nature. Biological dehydrogenation is illustrated from two aspects: chemistry of biocatalytic dehydrogenation and biocatalysts of dehydrogenation. Biological dehydrogenation reactions usually occur at very mild conditions and have very high selectivity. The catalysts for these processes are usually enzymes (or cells producing these enzymes). Enzymes having dehydrogenation capacities are usually dehydrogenases, oxidases, etc., and most of them need a coenzyme or a cofactor to work with them.

    Highly efficient Bi-promoted ZrO2-based materials for non-oxidative propane dehydrogenation
    Chemical Communications (2023)
    Tatiana OtroshchenkoEvgenii V. Kondratenko
    The presence of Bi 2 O 3 in the lattice or on the surface of ZrO 2 -based materials provokes creation of coordinatively unsaturated Zr 4+ cations under reductive conditions. Such sites are catalytically active for non-oxidative dehydrogenation of propane.

    Technologic Progress of Preparing Propene by Propane Dehydrogenation
    Hebei Journal of Industrial Science & Technaology (2003)
    Wen Cui
    Propene is a colorless combustible unsaturated gaseous hydrocarbon. Domestic and foreign development of preparing propene by propane dehydrogenation is outlined in this paper. Thermodynamics of propane dehydrogenation is analysed and it is reported that the reaction is reversible,moleculeincreasing and intensely thermonegative;catalyst of good selectivity must be adopted in order to increase propane selectivity. Several methods of preparing propane are summarized, which include propane dehydrogenation in membrane reactor and oxidative dehydrogenation where oxygen and carbon dioxide are used as oxidant.

    Propane Dehydrogenation Catalysis of Titanium Hydrides: Positive Effect of Hydrogen Co-feeding
    Chemistry Letters (2021)

    Abstract This study investigated non-oxidative propane dehydrogenation over TiH2. It was found that H2 co-feeding positively affected dehydrogenation, improving the propylene formation rate. In situ spectroscopic characterization of TiH2 in the presence of H2 indicated that partially dehydrogenated titanium hydrides are active for dehydrogenation.

    A METHOD FOR MAINTENANCE OF CURIE QUANTITIES OF Y90-DTPA IN THE HUMAN BODY FOR DEFINED TIME PERIODS: TECHNIQUE AND DOSIMETRY.

    A procedure is described by which a radioactive isotope may be maintained at a constant level within the body for a specified period followed by rapid removal of the isotope from the body under controlled conditions. The particular isotope used in these experiments was yttrium-90 chelated with DTPA. The procedure lends itself to use with any radioactive isotope which is either quantitatively excreted by the kidneys or which can be attached firmly to a suitable chelating agent that is rapidly cleared from the body by the kidneys. The methods and equipment necessary for continuous processing and intravenous recycling of urine containing high concentiations of a radioisotope are described. A method for estimating dosimetry is presented for injected Y/sup 90/-DTPA which is in equilibrium with plasma. However, this method has general applicabilities for any BETA or alpha emitting isotope used in the manner described. (auth)
