耐高温抗盐纳米渗吸剂的制备及性能评价
Preparation and performance evaluation of high-temperature and salt-resistant nano-adsorbent
摘要
Abstract
A kind of high-temperature and salt-resistant amino-functionalized graphene oxide nano-adsorbent(sj-1)was synthesized through covalent functional modification with amino-functionalized graphene oxide(sj-s),glutaraldehyde,and sodium 4-aminobenzenesulfonate as raw materials.The adsorbent was characterized by methods such as FTIR,Raman,TEM,and particle size and Zeta potential analysis.The temperature resistance,salt resistance,oil-water interfacial tension,stability,and the capacity of sj-1 to enhance oil recovery were investigated.The experimental results indicate that the 4-aminobenzenesulfonate groups were successfully grafted onto sj-s.sj-1 has good self-dispersibility in water and good stability at a temperature of 130 ℃ and a salinity of 16 × 104mg/L.When the core permeability is 3.814 × 10-4μm2,the oil absorption recovery effect could reach 37.9％.The spontaneous oil absorption recovery effect of sj-1 is superior to that of sj-s.关键词
