The present disclosure relates to dehydrogenation catalysts based on one or more certain group 13 and group 14 elements that further include additional metal components, to methods for making such catalysts, and to methods for dehydrogenating hydrocarbons using such catalysts. One aspect of the disclosure provides a calcined dehydrogenation catalyst that includes a primary species P1 selected from the group consisting of Ga, In, Tl, Ge, Sn and Pb and combinations thereof; a primary species P2 selected from the lanthanides; a promoter M1 selected from the group consisting of Ni, Pd and Pt; a promoter M2 selected from the group consisting of Li, Na, K, Rb, Cs, Be, Mg, Ca, Sr and Ba, on a silica-alumina support.

Dehydrogenation catalysts and methods for preparing and using them

The present disclosure relates generally to catalyst materials and processes for making and using them. More particularly, the present disclosure relates to molybdenum, bismuth and iron-containing metal oxide catalyst materials useful, for example, in the partial oxidation or ammoxidation of propylene or isobutylene, processes for making them, and processes for making acrolein, methacrolein, acrylonitrile, and methacrylonitrile using such catalysts.

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.

The present invention relates to a method for producing a supported catalyst, a catalyst which is obtainable using the method, and use thereof for the partial oxidation or ammoxidation of olefins, in particular for the oxidation of propene to acrolein, of isobutene to methacrolein, and/or the ammoxidation of propene to acrylonitrile. The method according to the invention includes the following steps: a) providing a solution in which precursor compounds of the catalytically active component are essentially completely dissolved in a suitable solvent; b) bringing the solution obtained in step a) into contact with a (chemically) inert, porous support having a specific surface of 1 to 500 m/g; c) heat treatment of the material obtained in step b), in which the precursor compounds of the catalytically active component are converted to their oxides.

The present disclosure relates to metal oxide catalyst materials useful, for example, in the ammoxidation of propylene or isobutylene, processes for making them, and processes for making acrylonitrile and methacrylonitrile using such catalyst materials. In certain aspects, a catalyst material is a fused composite of a metal oxide catalyst and nanoparticulate silica, the nanoparticulate silica comprising in the range of about 40 wt % to about 80 wt % of silica having a particle size in the range of 10 nm to 35 nm, and in the range of about 20 wt % to about 60 wt % of silica having a particle size in the range of 36 nm to 80 nm. The metal oxide catalyst can be, for example, a molybdenum-containing mixed metal oxide catalyst.

Metal oxide catalyst material and processes for making and using same

Ethylene glycol and propylene glycol may be made by hydrogenolysis of a polyol comprising the steps of reacting a polyol with hydrogen in the presence of a hydrogenolysis catalyst. The hydrogenolysis comprises nickel, one or more promoter, and one or more support. The promoter is selected from bismuth, silver, tin, antimony, gold, lead, thallium, cerium, lanthanum, and manganese. The support is selected from zirconia and carbon. A zirconia support comprises a zirconia textual promoter, which is selected from Cr, Mo, W, Nb, Ce, Ca, Mg, La, Pr, Nd, Al, and P. If the support comprises carbon, then the promoter is selected from bismuth and antimony. In another embodiment, if the support comprises carbon, then both the promoter is selected from bismuth and antimony, and the catalyst comprises copper. In another embodiment, the catalyst additionally comprises copper.

The present invention relates to a class of luminescent and conductive polymer compositions having chromophores, and particularly solid films of these compositions exhibiting increased luminescent lifetimes, quantum yields and amplified emissions. These desirable properties can be provided through polymers having rigid groups designed to prevent polymer reorganization, aggregation or &#x3c0;-stacking upon solidification. These polymers can also display an unusually high stability with respect to solvent and heat exposures. The invention also relates to a sensor and a method for sensing an analyte through the luminescent and conductive properties of these polymers. Analytes can be sensed by activation of a chromophore at a polymer surface. Analytes include aromatics, phosphate ester groups and in particular explosives and chemical warfare agents in a gaseous state. The present invention also relates to devices and methods for amplifying emissions by incorporating a polymer having an energy migration pathway and/or providing the polymer as a block co-polymer or as a multi-layer.

A process for the ammoxidation of a saturated or unsaturated or mixture of saturated and unsaturated hydrocarbon to produce an unsaturated nitrile, said process comprising contacting the saturated or unsaturated or mixture of saturated and unsaturated hydrocarbon with ammonia and an oxygen-containing gas in the presence of a catalyst composition comprising molybdenum, vanadium, antimony, niobium, tellurium, optionally at least one element select from the group consisting of titanium, tin, germanium, zirconium, hafnium, and optionally at least one lanthanide selected from the group consisting of lanthanum, cerium, praseodymium, neodymium, samarium, europium, gadolinium, dysprosium, holmium, erbium, thulium, ytterbium and lutetium. Such catalysts are characterized by very low levels of tellurium in the composition. Such catalyst compositions are effective for the gas-phase conversion of propane to acrylonitrile and isobutane to methacrylonitrile (via ammoxidation).
