摘要： A mixed basic metal sulfide catalyst having the formula:xA.yB.zC.qSwherein A is an alkali metal selected from lithium, sodium, potassium, rubidium, cesium and mixtures thereof; B is a cation which has an ionization state 1 greater than the ionization state of C; B is selected from scandium, yttrium, lanthanum, actinium, aluminum, boron and mixtures thereof when C is selected from beryllium, magnesium, calcium, strontium, barium, radium, zinc, cadmium, mercury and mixtures thereof and B is selected from titanium, zirconium, hafnium, silicon and mixtures thereof when C is selected from scandium, yttrium, lanthanum, actinium, aluminum, boron and mixtures thereof; x and y are in mole fractions of z such that when z=1 then x=0.001 to 0.25, and y=0.001 to 0.25; and q is a number necessary to maintain charge balance with S being sulfur.The catalyst is useful for oxidative coupling of methane and aliphatic and alicyclic hydrocarbon compounds with an aromatic compound to produce higher molecular weight hydrocarbons; and for dehydrogenating hydrocarbon compounds to produce unsaturated aliphatic and alicyclic chains.

摘要： A method for dehydrogenating dehydrogenatable hydrocarbons which comprises contacting said hydrocarbons with an oxide of Pr having combined therewith an amount of alkali and/or alkaline earth metal which is sufficient to improve the selectivity to dehydrogenated hydrocarbon products. The oxide is reduced by the contact which is carried at about 500.degree. to 1000.degree. C. Reducible oxides of Pr are regenerated by oxidizing the reduced composition with oxygen. Solids prepared from the oxide Pr.sub.6 O.sub.11 are particularly effective in the process.

摘要： Para-ethyltoluene dehydrogenation catalyst compositions and processes for using such catalysts are provided. The catalyst compositions comprise a catalytically active iron compound, e.g., iron oxide; a potassium catalyst promoter, e.g., potassium carbonate; an optional chromium compound stabilizer, e.g., chromic oxide, and a calcium compound, e.g., calcium oxide. Utilization of particular amounts of calcium compound in dehydrogenation catalyst compositions of this type will provide a catalyst especially suitable for promoting the selective dehydrogenation of para-ethyltoluene to form para-methylstyrene in improved yields.

摘要： Isobutane in a C.sub.4 hydrocarbon feed stream is converted to methacrolein in an integrated two-step process. Isobutane is dehydrogenated in a first step to isobutylene, hydrogen, and by-products and the reaction effluent is passed directly into a second step where isobutylene is oxidized to methacrolein without significant oxidation of the hydrogen and by-products. Any normal butenes present are converted to butadiene. The methacrolein and by-products may be separated and the unreacted isobutylene and isobutane recycled to the first step. Alternatively, the effluent from the second step may be used as feed to a further oxidation step for conversion of methacrolein to methacrylic acid.
