Abstract: Oxidative dehydrogenation (ODH) of alkanes to alkenes, e.g., propane to propylene, may use solid phase oxygen in VOx based mixed oxide catalysts. Beyond catalysis, the metal oxide species provide lattice oxygen. The catalysts can be prepared by depositing vanadium oxide(s) on ?-Al2O3 mixed with various alkaline earth metal oxide support, e.g., CaO, MgO, BaO, etc. Surface area, acidity, and reduction properties of the catalyst systems can be modified by the support. The catalysts may allow multistage reduction of VOx, indicating different VOx species. Vanadium on ?-Al2O3/CaO can suppress COx species, while vanadium on ?-Al2O3/BaO can yield at least ca. 49% olefins.

An external combustion and a heat recovery steam generator (HRSG) are employed to maximize the efficiency of a gas turbine generator and steam turbine generator. The integrated CLC system provides a clean and efficient diesel fueled power generation plant with high CO2 recovery.

Abstract: A method for quantitative determination of nonisothermal thermooxidative degradation effects of a polyolefin material containing a residual catalyst. The method includes determining a first thermooxidative degradation by obtaining a thermogravimetric analysis spectrum of polyolefin, and then modifying the first thermooxidative degradation based on a structure of the residual catalyst to obtain final thermooxidative degradation properties of the polyolefin.
