摘要： A catalyst for oxidative dehydrogenation of organic compounds is provided by forming a solution of catalyst precursor components comprised of Fe+3 and Zn+2 cations and at least one other modifier element cation in water to form an aqueous solution of the catalyst precursor components. The modifier element cation has a standard reduction potential of from greater than about −2.87 E° (V) to less than about −0.036 E° (V) with a valence of +2. A base is separately and simultaneously added to the aqueous solution in amounts to maintain the pH of the aqueous solution at a pH of from about 8.5 to about 9.5 as the catalyst precursor components. The catalyst precursor components are allowed to react and precipitate out of solution as a precipitate. The resulting precipitate is calcined to form a modified zinc ferrite catalyst compound.

摘要： The invention is a heteropoly acid compound catalyst composition, a method of making the catalyst composition and a process for the oxidation of saturated and/or unsaturated aldehydes to unsaturated carboxylic acids using the catalyst composition. The catalyst composition is a heteropoly acid compound containing molybdenum, vanadium, phosphorus, cesium, bismuth, copper and antimony. Thermal stability is achieved with higher cesium content (up to less than 3.0) but antimony, copper and bismuth must be present to maintain good activity.The catalyst is made by dissolving compounds of the components of each of the heteropoly acid compounds in a solution, precipitating the heteropoly acid compounds, obtaining a catalyst precursor and calcining the catalyst precursor to form a heteropoly acid compound catalyst.Unsaturated aldehydes, such as methacrolein, may be oxidized in the presence of the heteropoly acid compound catalyst to produce an unsaturated carboxylic acid, such as methacrylic acid.

摘要： Disclosed is a catalyst composition which does not contain antimony or molybdenum for the vapor phase ammoxidation of alkanes of the general empirical formula: VWaBibMcOxwherein M is one or more elements selected from sodium, cesium, magnesium, calcium, barium, boron, yttrium, indium, aluminum, gallium, tin, titanium, silicon, zirconium, germanium, niobium and tantalum, a is 0.2 to 10, b is 0.5 to 5, c is 0 to 10 and x is determined by the valence requirements of the elements present. The catalyst precursor is precipitated from a solution or slurry of compounds of vanadium, tungsten, bismuth and, optionally, M, then separated, dried and calcined to give a phase or combination of phases active in the ammoxidation of low-weight paraffins to the corresponding unsaturated mononitriles. Nitriles may be produced in a gas phase catalytic reaction of alkanes with ammonia and oxygen in the presence of the catalyst.
