  • Patent number: 11439992
    Abstract: The present disclosure relates to processes for formation of a molecular sieve, particularly a metal-promoted molecular sieve, and more particularly an Iron(III) exchanged zeolite. Preferably, the zeolite is of the chabazite form or similar structure. The processes can include combining a zeolite with Iron(III) cations in an aqueous medium. The process can be carried out at a pH of less than about 7, and a buffering material can be used with the aqueous medium. The processes beneficially result in Iron exchange that can approach 100% along with removal of cations (such as sodium, NH4, and H) from the zeolite. An Iron(III)-exchanged zeolite prepared according to the disclosed processes can include about 2,000 ppm or less of cation and about 1% by weight or greater of Iron(III). The disclosure also provides catalysts (e.g., SCR catalysts) and exhaust treatment systems including the Iron(III)-exchanged zeolite.

  • Patent number: 11433385
    Abstract: This disclosure provides a method to produce highly attrition resistant pellets by encapsulating reactive components in a vitrified clay outer layer. The reactive component mixture is present relative to the clay substrate in a weight ratio of part per 60-100 part to about 60 parts of the clay substrate. The reactive components are agglomerated first, and clay substrate is added to form the outer layer of the pellet. The pellets are calcined at temperatures above 1200 C to form a vitrified clay semi porous outer layer providing high strength to the pellet while facilitating the gas transfer for the reaction with the encapsulated reactive components. Pellets containing CuO—Fe2O3-alumina oxygen carrier for chemical looping combustion of fuel demonstrated high attrition resistance and high reactivity with methane.
