Enhanced performance of alumina for the removal of low-level fluorine
from gas streams
摘要:
Low-level fluorine concentrations are removed from gases by conducting a gas stream containing fluorine over an alumina treated with chromium oxide material, thereby effectively eliminating fluorine from the gas while preventing the formation of toxic oxygen difluoride by-product.
