REMOVAL METHOD OF CARBON DIOXIDE IN SYNGAS USING ADSORBENT FOR LOW TEMPERATURE APPLICATIONS

摘要

PURPOSE: A method for eliminating carbon dioxide in synthetic gas using a low temperature carbon dioxide absorber is provided to selectively eliminate carbon dioxide from the synthetic gas containing hydrogen and the carbon dioxide and separate pure hydrogen. CONSTITUTION: An absorber carries 10 to 50 weight% of sodium carbonate in alumina. 20 weight% of absorber is used for eliminating carbon dioxide from synthetic gas containing hydrogen and carbon dioxide. The carbon dioxide is absorbed to be converted hydrogen carbonate salt and is eliminated from the synthetic gas at low temperature. A reverse reaction is generated at high temperature.
