A catalyst includes LTA zeolite including copper ions, wherein a Si/Al ratio of the LTA zeolite is 2 to 50. The catalyst is coated on a honeycomb carrier or a filter. The catalyst removes NOx from a reaction gas at 100&#xb0; C. or above. The catalyst has an NOx conversion rate of 80% at 450&#xb0; C. or above.

Catalyst and method for preparing catalyst

A method for manufacturing a zeolite catalyst includes: manufacturing a first Linde Type A (LTA) zeolite using an LTA seed; manufacturing a second LTA zeolite including ions by substituting ions to the first LTA zeolite; and manufacturing a copper LTA zeolite by performing copper ion exchange on the second LTA zeolite.

The present invention relates to a PST-20 zeolite having a novel skeletal structure, its preparation method, and a selective separation and adsorption method for a gas using the PST-20 zeolite. More specifically, the present invention relates to a method of preparing a microporous aluminosilicate PST-20 zeolite having a novel skeletal structure totally different from the skeletal structure of known zeolites and using the PST-20 zeolite as an adsorbent/separator capable of selectively adsorbing/separating carbon dioxide to separate and collect carbon dioxide with high purity from burned gases or natural gases.

A catalyst manufacturing method includes: preparing UZM-35 zeolite; manufacturing ion-containing UZM-35 zeolite by substituting ions in a structure of the UZM-35 zeolite; and manufacturing metal-containing UZM-35 zeolite by exchanging copper (Cu) ions or iron (Fe) ions in a structure of the ion-containing UZM-35 zeolite.

Catalyst and manufacturing method of catalyst

The present invention relates to selectively isolating gases using a natrolite-based zeolite, and more particularly, to a novel natrolite-based zeolite and to selectively isolating hydrogen and/or helium gas using a natrolite-based zeolite. The present invention is characterized in that gas containing hydrogen is brought into contact with a natrolite-based zeolite to selectively isolate the hydrogen. The present invention provides a sorbent which can selectively isolate hydrogen and/or helium, and provides a method for isolating the hydrogen and/or helium at room temperature or at a high temperature.
