Perovskite Hollow-Fiber Membranes for the Production of Oxygen-Enriched Air

摘要

Oxygen-enriched air with 30-50 vol% O_2 is used in a number of industrial processes,for example,in the synthesis of ammonia,the Claus process,and the regeneration of the catalyst for the fluid-catalytic-cracking (FCC) process. Another application of O_2-enriched air is the most efficient use of methane in high-temperature furnaces or cement kilns.
