摘要:An improved method is disclosed for the selective synthesis of low molecular weight olefins, particularly C2 and C3 olefins inclusive, which method comprises the steps of passing a CO and H2 synthesis gas stream over a catalyst at a temperature and pressure and for a time sufficient to generate the desired olefinic products, wherein the improvement consists in using as a catalyst ruthenium on a support selected from the group consisting of a manganese oxide, other manganese-containing oxides or mixtures of various manganese oxides. The weight loading of the ruthenium may range from about 0.01 to about 15 wt. % based on the total catalyst weight. The operating conditions of the instant process are the standard Fischer-Tropsch synthesis reaction parameters, preferably an H2/CO mole ratio of from about 10 to about 0.1, a space velocity of from about 100 hr-1 to about 50,000 hr-1, a temperature of from about 100 DEG C. to about 500 DEG C. and a pressure of from about 103 to about 1.03x105 kPa (103 kPa - 1 atm). The instant process is also marked by a reduced methane make.

摘要:Disclosed is a ruthenium-based catalyst for ammonia synthesis, preparation method and use thereof. The ruthenium-based catalyst comprises Ru—Ba-A core-shell structure which comprises a ruthenium nanoparticle as a core covered with a first shell and a second shell sequentially, wherein the first shell consists of a barium nanoparticle, and the second shell consists of a metal oxide. The Ru—Ba-A core-shell structure can effectively preventing agglomerations of ruthenium nanoparticles during the use of the catalyst and avoiding direct contact between the ruthenium nanoparticles and the metal oxides. In addition, barium nanoparticles have a promoting effect as an electronic promoter, which can effectively improve the stability and catalytic activity of ruthenium-based catalyst for ammonia synthesis, especially in the system for synthesizing ammonia from a coal gas.

标题 :Hydrocarbon synthesis from CO and H2 using Ru supported on group VB metal oxides
发明人：TAUSTER SAMUEL J; VANNICE M ALBERT
权利人:EXXON RESEARCH ENGINEERING CO
摘要:An improved method for the synthesis of hydrocarbons with reduced methane formation and for the selective generation of olefinic hydrocarbons, preferably C2-C5 olefins inclusive, which method comprises the steps of passing a CO and H2 synthesis gas stream over a catalyst at a temperature and pressure for a time sufficient to generate the desired olefinic products, wherein the improvement consists in using as a catalyst ruthenium on a support comprising at least one refractory Group VB metal oxide. The weight loading of the ruthenium may range from about 0.01 to about 15 wt. % based on the total catalyst weight. The ruthenium average crystallite size is preferably less than 5 nm (50A). The operating conditions of the instant process are typical for Fischer-Tropsch synthesis.

摘要:Disclosed is a method of making and using a titania supported palladium catalyst for the single step synthesis of 2-ethylhexanal from a feed of n-butyraldehyde. This titania supported palladium catalyst demonstrates high n-butyraldehyde conversion but also produces 2-ethylhexanal in an appreciable yield with maintained activity between runs. This method provides a single step synthesis of 2-ethylhexanal from n-butyraldehyde with a catalyst that can be regenerated that provides cleaner downstream separations relative to the traditional caustic route.
