In this paper, pitch—based spherical activated carbon(PSAC)was modified by the air—oxidation treatment.
利用空气氧化处理法对沥青基球状活性炭进行了改性。
PSAC member companies represent over 80 per cent of the business volume generated in the petroleum services industry.
球状活性炭的成员公司代表超过百分之八十的业务量中产生的石油服务行业。
As the intensity of air—oxidation treatment increased, the surface area of the PSAC decreased, but its total pore volume increased.
并且随着氧化强度的增强，沥青基球状活性炭的比表面积减小，但总孔容增加。
