摘　　要：评价比较了CNA - 875、CNA - 795和CNA -E对呋喃的吸附解吸性质。测试了在不同再生条件下CNA -795对呋喃的脱除精度和吸附容量。再生温度为 12 0～ 15 0℃ ,呋喃脱除精度为 5 0× 10 -6时 ,CNA - 795的吸附容量为6 3 6ml/ g。The adsorption and desorption properties of CNA-875,CNA-795 and CNA-E adsorbents to furan were estimated and compared.The degree of furan removing and adsorbing capacity with CNA-795 in different regenerating conditions were mensurated.When temperature for regenerating was 120～150℃ and furan was removed to 50×10 -6 ,the capacity for CNA-795 was 63 6ml/g.
