The present invention provides an oxygen selective adsorbent containing oxides of BaSrMg(CO)or BaSrCOparticles, increasing transition oxygen partial pressure, and representing high thermal stability and excellent oxygen sorption cavity, by adding another metal such as Sr to Ba which is active element for oxygen adsorption, so as to be capable of desorbing oxygen under lower vacuum even at the same operating temperature than the existing oxygen selective adsorbent; and a preparation method thereof.

Oxygen selective adsorbent for easy desorption and preparation method thereof

A highly selective carbon monoxide adsorbent and a method of preparing the highly selective carbon monoxide adsorbent are provided. The highly selective carbon monoxide adsorbent includes a boehmite or pseudo-boehmite in which a copper compound is dispersed.

Highly selective carbon monoxide adsorbent and method of preparing the same

Disclosed is a method of removing calcium from a hydrocarbon fraction using an extraction agent including 2-oxopropanal or derivatives thereof, the method including (S1) adding a hydrocarbon fraction with an extraction agent including 2-oxopropanal or derivatives thereof to give a mixture, (S2) converting an oil-soluble calcium compound into a water-soluble calcium compound by reacting the hydrocarbon fraction with the 2-oxopropanal or derivatives thereof, and (S3) removing the water-soluble calcium compound.

Method of removing calcium from hydrocarbon fraction using extraction agent including 2-oxopropanol or derivatives thereof

Provided is a preparation method of an oxygen-selective adsorbent selectively adsorbing oxygen in the air and an oxygen-selective adsorbent prepared thereby. The preparation method includes: preparing BaMg(CO)particles or particles in which MgCOor Mg(OH)are attached to the outside of BaMg(CO); and sintering the particles at a high temperature. The oxygen-selective adsorbent according to the present invention may adsorb oxygen in the air at a fast rate as compared with an existing oxygen-selective adsorbent and have high thermal stability and excellent oxygen adsorptivity.

Oxygen-selective adsorbent having fast adsorption rate and preparation method thereof
