炭黑分散法制备双重孔分布的γ-Al_2O_3载体
Preparation of dual pore size distributed γ-Al_2O_3 with pore-expanding agent of dispersed carbon black
摘要
Abstract
The γ-Al2O3 carrier with large pore diameter and appropriate pore size distribution was prepared by using carbon black as an enlarge agent.The effects of carbon black types,content and dispersion in the γ-Al2O3 power,such as the chemical properties and content of surfactant dispersant,on the pore distribution of γ-Al2O3 were studied.The results showed that dispersant agents,favoring the carbon black dispersion,could reduce the amount of carbon black and benefit the pore enlargement.By combining dispersant agents and sonication,the pore size distribution could be concentrated at 6nm and 10-20 nm(or 20-30 nm)with only 10% carbon black.关键词
