超声辅助酸碱改性活性炭纤维对DBT脱硫性能的研究
Study on DBT desulfurization performance with activated carbon fiber modified by ultrasonic assisted acid-alkali
摘要
Abstract
Activated carbon fiber(ACF)was modified with different concentration and temperature of acid and alkali solutions.It was concluded that the ACF modified with 8 mol/L,90 ℃ mixed acid had best removal effects for DBT.The structure of modified ACF was characterized with BET,FTIR and Boehm titration.The results showed that the specific surface area,pore volume and oxygen-containing functional groups of ACF were significantly increased after modification.The absorption capacity of the modified ACF reached 49.61 mg/g under the optimized conditions of ultrasonic time 80 min,adsorption temperature 50 ℃,adsorption time 1.5 h,and mass ratio of oil to adsorbent of 100:1.The modified ACF had good reproducibility to remove DBT,and the fitting of isothermal adsorption data was in accordance with Langmuir equation,the saturated sulfur capacity could reach 57.80 mg/g.关键词
