摘要： The invention relates to a catalyst and process for making syngas mixtures including hydrogen, carbon monoxide and carbon dioxide. The process comprises contacting a gaseous feed mixture containing carbon dioxide and hydrogen with the catalyst, where the catalyst comprises Mn oxide and an auxiliary metal oxide selected from the group consisting of La, Ca, K, W, Cu, Al and mixtures or combinations thereof. The process enables hydrogenation of carbon dioxide into carbon monoxide with high selectivity, and good catalyst stability over time and under variations in processing conditions. The process can be applied separately, but can also be integrated with other processes, both up-stream and/or down-stream including methane reforming or other synthesis processes for making products like alkanes, aldehydes, or alcohols.

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： A method for making a syngas mixture is accomplished by introducing a gaseous feed mixture containing carbon dioxide and hydrogen into a reactor containing a non-zinc catalyst. The catalyst contacts the gaseous feed mixture to form syngas mixture reaction products. The reaction takes place in the presence of nickel-containing and/or iron-containing materials. The gaseous feed mixture is introduced into the reactor at a reactor inlet temperature of from 700° C. to 800° C., with the reaction being carried out at substantially adiabatic conditions or wherein the syngas mixture reaction products are removed from the reactor at a reactor outlet temperature of from 500° C. to 600° C.

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.
