Abstract: The present invention provides a solid-phase catalyst for decomposing hydrogen peroxide comprising a permanganate salt and a manganese (II) salt. The solid-phase catalyst stays a solid state in the form of nanoparticles at the time of hydrogen peroxide decomposition, and thus can be recovered for reuse and also has an excellent decomposition rate. In the method for producing a solid-phase catalyst for decomposing hydrogen peroxide according to the present invention, a solid-phase catalyst is produced from a solution containing a permanganate salt, a manganese (II) salt, and an organic acid, so that the produced solid-phase catalyst is precipitated as a solid component even after a catalytic reaction, and thus is reusable and environmentally friendly, and cost reduction can be achieved through the simplification of a catalyst production technique.

Abstract: The present invention relates to novel catalysts for oxidative esterification, by means of which, for example, (meth)acrolein can be converted to methyl (meth)acrylate. The catalysts of the invention are especially notable for high mechanical and chemical stability even over very long periods. This especially relates to an improvement in the catalyst service life, activity and selectivity over prior art catalysts which lose activity and/or selectivity relatively quickly in continuous operation in media having even a small water content.

Abstract: Active catalysts for the treatment of a low temperature exhaust gas stream are provided for the direct decomposition removal of NOx from an exhaust gas stream. The catalyst system may include a mixed oxide composition including cerium oxide and nickel oxide CeO2—NiO. The exhaust gas stream may be provided at a temperature of from about 400° C. to about 650° C. Methods for making the catalyst include co-precipitation techniques, using KOH as a precipitating agent. The catalyst system is configured to catalyze a decomposition of the NOx to generate N2 without the presence of a reductant. The catalyst may be a cubic structure, with nickel incorporated in a cubic lattice of cerium. The catalyst composition may be represented as Ce0.5Ni0.5O2.

Abstract: Provided is a phosphorus-containing ultrastable Y-type rare earth (RE) molecular sieve and the preparation method thereof. The method is: based on NaY molecular sieve as a raw material, obtaining “one-exchange one-roast” RE-Na Y-type molecular sieve through the steps of exchanging with RE, pre-exchanging with dispersing, and the first calcination; and then performing ammonium salt exchange, phosphorus modification, and the second calcination on the “one-exchange one-roast” RE-Na Y-type molecular sieve, wherein the sequence of the RE exchange and the pre-exchange with dispersing is unlimited, and the sequence of the ammonium salt exchange and the phosphorus modification is unlimited as well. The obtained molecular sieve contains RE oxide 1-20 wt %, phosphorus 0.1-5 wt %, and sodium oxide no more than 1.2 wt %, and has a crystallization degree of 51-69% and a lattice parameter of 2.449-2.469 nm. Heavy oil conversion rate can be increased by using the molecular sieve as an active component in a catalytic cracking catalyst.

Abstract: A method for synthesizing a crystalline molecular sieve SSZ-13, characterized in that the method comprises bringing the following raw materials into contact in water under a crystallization condition: at least one tetravalent silicon source, at least one trivalent aluminum source, at least one alkali metal compound, choline cations and/or SSZ-13 seed crystals, and hydroxide ions. The method avoids using benzyl trimethyl quaternary ammonium ions (BzTMA+) or N,N,N-trimethyl-1-amantadine cations as structure-directing agents, and obtains high-quality crystal molecular sieve SSZ-13. Due to the use of a low-cost nontoxic structure-directing agent, the method has low production price by employing a low-cost nontoxic template, and can be popularized for application.
