titleOfInvention | Method for Purifying Nitrogen Trifluoride Gas Using Zeolite 5A Impregnated with Alkaline Earth Metal |
abstract | The present invention relates to a method for purifying nitrogen trifluoride gas, and more particularly, carbon tetrafluoride (CF 4) through a column packed with zeolite 5A impregnated with alkaline earth metal and heated at 150 to 600 ° C. for 30 minutes to 100 hours. The present invention relates to a method for purifying nitrogen trifluoride gas, which comprises adsorbing nitrogen trifluoride (NF 3 ) gas, and selectively adsorbing only nitrogen trifluoride. The present invention relates to a carbon tetrafluoride gas from nitrogen trifluoride gas according to the present invention. It can provide an effective way to remove the.n n n Nitrogen trifluoride, NF3, carbon tetrafluoride, CF4, zeolite, zeolite 5A, impregnation |
