OXYGEN SELECTIVE ABSORBENT WITH RAPID ABSORBENT RATE AND A METHOD FOR MANUFACTURING THE SAME CAPABLE OF IMPROVING THERMAL STABILITY AND OXYGEN ABSORBING PERFORMANCE

摘要

PURPOSE: An oxygen selective absorbent with rapid absorbent rate and a method for manufacturing the same are provided to rapidly absorb oxygen from atmosphere.;CONSTITUTION: A method for manufacturing an oxygen selective absorbent with rapid absorbent rate includes the following: BaMg(CO_3)_2 particles or BaMg(CO_3)_2 particles with MgCO_3 or Mg(OH)_2 attached on the external sides are prepared; and the particles are fired at high temperatures. In the BaMg(CO_3)_2 particles with MgCO_3 or Mg(OH)_2 attached on the external sides, the molar ratio of the MgCO_3 or Mg(OH)_2 to BaMg(CO_3)_2 is 1 : 10. The BaMg(CO_3)_2 particles are prepared by dispersing the mixture of barium containing compounds and carbonate in distilled water and adding a magnesium carbonate precursor in the dispersed solution.;COPYRIGHT KIPO 2013;[Reference numerals] (AA) Absorbed amount/saturated absorbed amount; (BB) Time(minutes); (CC) Comparative example 1; (DD) Example 1; (EE) Example 2
