  • Method of fabricating a high-temperature COcapture agent
    Patent number: 9089837
    Abstract: A novel method for making a CO2 capture agent is provided. The capture agent is made of a calcium/iron salt. The capture agent is prevented from degradation at high temperature. The capture agent is fit to be used at various temperatures in high CO2 densities for achieving high CO2 capture capacity, environmental protection and low power consumption.
    Type: Grant
    Filed: September 30, 2013
    Date of Patent: July 28, 2015
    Assignee: INSTITUTE OF NUCLEAR ENERGY RESEARCH, ATOMIC ENERGY COUNCIL
    Inventors: Ching-Tsung Yu, San-Yuan Chen, Wei-Chin Chen, Po-Hsueh Chang

  • CARBON DIOXIDE ADSORBENT, THE MANUFACTURING METHOD THEREOF, AND THE USE METHOD THEREOF
    Publication number: 20140312272
    Abstract: A method for manufacturing a carbon dioxide adsorbent is provided. The method comprises steps of providing a limestone having a first specific surface area, treating the limestone with acid solution to obtain a first substance having a second specific surface area larger than the first specific surface area, at the same time reacting the first substance with an anti-sintering agent to obtain a second substance, and calcining the second substance to obtain the carbon dioxide adsorbent containing calcium-based oxides.
