  • M-exchanged beta zeolite, gas adsorbent comprising same, method for producing same, and method for removing nitrogen monoxide
    Patent number: 9968909
    Abstract: Provided are: a Mn+-exchanged beta zeolite which is useful for the catalytic removal of nitrogen monoxide contained in a gas to be purified even when oxygen is contained in the gas at a high concentration or when the gas has a low temperature; and a method for producing the Mn+-exchanged beta zeolite. The Mn+-exchanged beta zeolite according to the present invention has a SiO2/Al2O3 ratio of 7 to 18, and is ion-exchanged by a Mn+ ion (wherein Mn+ represents a n-valent metal cation; n represents a numeral value of 1 to 3; and M represents an element selected from the group consisting of Ni, Co, Cu, Mn, Zn, Sn, Ag, Li, K, Cs, Au, Ca, Mg, Pt, Pd, Rh and Ir). The amount of the Mn+ ion carried on the Mn+-exchanged beta zeolite is preferably from 0.01 to 2.5 mmol/g relative to the amount of the Mn+-exchanged beta zeolite.

  • Zeolite, manufacturing method of the same, and catalytic cracking catalyst of paraffin
    Patent number: 9895683
    Abstract: A MSE-type zeolite which has a Si/Al ratio of 5 or more, is a proton-type zeolite, and is obtained by transforming a raw material MSE-type zeolite synthesized without using a structure directing agent into an ammonium-type zeolite through ion exchange, then, exposing the MSE-type zeolite to water vapor, and subjecting the exposed MES-type zeolite to an acid treatment.

  • ZEOLITE, MANUFACTURING METHOD OF THE SAME, AND CATALYTIC CRACKING CATALYST OF PARAFFIN
    Publication number: 20170368539
    Abstract: Provided is a beta-type zeolite which has a high catalytic activity and is not easily deactivated. The beta-type zeolite of the invention has a substantially octahedral shape, has a Si/Al ratio of 5 or more, and is a proton-type zeolite. The Si/Al ratio is preferably 40 or more. This beta-type zeolite is preferably obtained by transforming a raw material beta-type zeolite synthesized without using a structure directing agent into an ammonium-type zeolite through ion exchange, then, exposing the beta-type zeolite to water vapor, and subjecting the exposed beta-type zeolite to an acid treatment.
