The present disclosure relates to a catalyst for direct nonoxidative conversion of methane and a method of preparing the same, and more particularly to a method of preparing a catalyst for direct nonoxidative conversion of methane, in which a catalyst optimized for the direct conversion reaction of methane can be easily prepared without precise control of the reaction conditions for direct conversion of methane, thereby simultaneously maximizing the catalytic reaction rate and minimizing coke formation, and exhibiting stable catalytic performance even after long-term operation, and to a catalyst for direct nonoxidative conversion of methane prepared using the above method.

A mesoporous mixed oxide catalyst that comprises silicon and at least one metal M that is selected from the group that consists of the elements of groups 4 and 5 of the periodic table and mixtures thereof, with the mass of metal M being between 0.1 and 20% of the mixed oxide mass.

Nickel-based catalysts comprising silicon modified nickel (nickel silicate) are provided, as are methods for using the catalysts to i) convert methane to CO and H.sub.2 (e.g. for use in synthetic chemical compound production); or to ii) convert methane to oxygenated hydrocarbons e.g. one or more of methanol, acetone, formaldehyde, and dimethyl ether. The catalysts are bifunctional and comprise both Ni metallic catalytic sites and acidic nickel-silicon catalytic sites, and the conversions are performed under moderate reaction conditions.

Bulk catalysts comprised of nickel, molybdenum, tungsten and titanium and methods for synthesizing bulk catalysts are provided. The catalysts are useful for hydroprocessing, particularly hydrodesulfurization and hydrodenitrogenation, of hydrocarbon feedstocks.

A novel mixed oxide material is disclosed which comprises molybdenum, vanadium, tellurium and niobium and the use of the mixed oxide material as catalyst for the oxidative dehydrogenation of ethane to ethene or the oxidation of propane to acrylic acid and a process for producing the mixed oxide material.

The present disclosure provides molecular sieves with intergrown phases of AEI and CHA topologies and a catalyst thereof. A preparation method for the molecular sieves include the following steps: mixing a hydroxyphosphono organic alkali R with an aluminum source and a silicon source to obtain a sol-gel precursor, putting the sol-gel precursor into a closed hydrothermal synthesis reactor for reaction, filtering the reaction solution, washing, drying, and calcination to obtain the molecular sieves with intergrown phases of AEI and CHA topologies. The molecular sieves and the catalyst thereof can be directly synthesized under mild conditions with a hydroxyphosphono organic alkali as a structure-directing agent and a phosphorus source, have a pH value of 6-9 and low requirements for corrosion resistance of production devices, and are suitable for large-scale production.
