Title:
METHOD OF REMOVING RESIDUE IN LIQUEFIED GAS AND REGENERATING METHOD OF ACTIVATED CARBON
Document Type and Number:
Japanese Patent JP3651881
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a method of removing residue in a liquefied gas using an adsorbent capable of being regenerated at a lower temperature compared to the conventional one and a method of regenerating the adsorbent.
SOLUTION: The method of removing the residue in the liquefied gas, is performed by allowing the liquefied gas to contact with a packed layer, in which activated carbon carrying platinum is filled, to adsorb the residue to the activated carbon. In the regenerating method of the adsorbent, is performed by oxidize the residue in the liquefied gas, which is adsorbed by the activated carbon, with oxygen to regenerate the activated carbon. The removing method of the residue in the liquefied gas has a removing process of the residue in the liquefied gas to adsorb the residue to the activated carbon by allowing the liquefied gas to contact with a packed layer, in which activated carbon carrying platinum is filled, and an activated carbon regenerating process to regenerate the activated carbon by oxidizing the residue in the liquefied gas, which is adsorbed by the activated, with oxygen and the processes are continuously repeated.
