Abstract: A selective catalytic reduction (SCR) catalyst composition effective in the abatement of nitrogen oxides (NOx) is provided. The SCR catalyst composition significantly increases the conversion of NOx relative to a Cu-chabazite reference catalyst composition at any temperature, and especially at low temperatures. A catalyst article, an exhaust gas treatment system, and a method of treating an exhaust gas stream, each including the SCR catalyst composition of the invention, are also provided. The SCR catalyst composition is particularly useful for treatment of exhaust from a lean-burn engine.

Abstract: 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.

Abstract: Zn-promoted and/or Ga-promoted cracking catalysts, such as cracking catalysts comprising an MSE framework zeolite or an MFI framework zeolite can provide unexpectedly superior conversion of branched paraffins when used as part of a catalyst during reforming of a hydrocarbon fuel stream. The conversion and reforming of the hydrocarbon fuel stream can occur, for example, in an internal combustion engine. The conversion and reforming can allow for formation of higher octane compounds from the branched paraffins.
