    Abstract: This disclosure relates to catalysts comprising gallium, cerium, and a mixed oxide support useful in the dehydrogenation of hydrocarbons, to methods for making such catalysts, and to methods for dehydrogenating hydrocarbons with such catalysts. For example, in one embodiment, a catalyst composition includes gallium oxide, present in the composition in an amount within the range of about 0.1 wt. % to about 30 wt. %, cerium oxide, present in the composition in an amount within the range of about 0.1 wt. % to about 15 wt. %, a promoter, M1, selected from Pt, Ir, La, or a mixture thereof, present in the composition in an amount within the range of about 0.005 wt. % to about 4 wt. %, a promoter, M2, selected from the group 1 elements (e.g., Li, Na, K, Cs), present in the composition in an amount within the range of about 0.05 wt. % to about 3 wt. %, and a support, S1, selected from alumina, silica, zirconia, titania, or a mixture thereof, present in the composition in an amount within the range of about 60 wt. % to about 99 wt. %.

    Abstract: Disclosed is a process for the manufacture of a chromium-containing catalyst with a reduced amount of chromium-(VI)-oxide which process comprises the steps: a) preparing a solid particulate chromium-containing oxidic catalyst comprising Cr-(VI)-oxide, b) introducing the solid particulate catalyst into a reactor in which the catalyst particles are mixed using process gas and/or mechanical means, c) introducing a reducing agent for chromium-(VI) into the reactor, d) treating the solid particulate catalyst with the reducing agent in the reactor for a time, at a temperature and at a pressure, so that the chromium-(VI) content in the particulate catalyst is considerably reduced by the reducing agent, and e) discharging the solid particulate catalyst comprising a reduced chromium-(VI) content from the reactor. The disclosed process is simple and efficient and allows manufacture of chromium-containing oxidic catalysts with low content of Cr-(VI)-oxide on an industrial scale.

    Abstract: The present disclosure relates to solid phosphoric acid (SPA) catalysts useful in the conversion of hydrocarbons, such as the oligomerization of olefins, to methods for making such SPA catalysts, and to methods for converting hydrocarbons by contacting hydrocarbons with such catalyst. For example, in certain embodiments, the disclosure provides a calcined solid phosphoric acid catalyst composition that includes phosphoric acid and silicon phosphates, and in which (i) one or more promoters each selected from the group consisting of boron, bismuth, tungsten, silver and lanthanum is present; (ii) the composition is a calcined product of a formable mixture including silica-alumina clay, silica fiber and/or silica alumina fiber; or (iii) the composition is a calcined product of a formable mixture including fumed silica.

    Abstract: Disclosed is a process for the manufacture of a chromium-containing catalyst with a reduced amount of chromium-(VI)-oxide which process comprises the steps: a) preparing a solid particulate chromium-containing oxidic catalyst comprising Cr-(VD-oxide, b) introducing the solid particulate catalyst into a reactor in which the catalyst particles are mixed using process gas and/or mechanical means, c) introducing a reducing agent for chromium-(VI) into the reactor, d) treating the solid particulate catalyst with the reducing agent in the reactor for a time, at a temperature and at a pressure, so that the chromium-(VI) content in the particulate catalyst is considerably reduced by the reducing agent, and e) discharging the solid particulate catalyst comprising a reduced chromium-(VI) content from the reactor.
