Abstract:

Activated carbon filled PEG/VPDF membranes with different activated carbon (AC) loading were prepared. The morphology and structure of the prepared AC-PEG/PVDF hybrid membranes were characterized. The thiophene/n-heptane mixture was used as a simulated gasoline system, the desulfurization of membranes were studied systematically. The results showed that the desulfurization of the AC-PEG/PVDF hybrid membranes were improved. When the content of activated carbon is 5% and the temperature is 85℃, the permeation flux and sulfur enrichment factor of the membrane were improved from 0.43 kg·(m2·h)-1 and 7.29 to 1.14 kg·(m2·h)-1 and 9.47, respectively.

Key words: activated carbon, PEG, pervaporation, desulfurization

摘要:

制备了不同活性炭(AC)填充量的AC-PEG/PVDF杂化膜,并对其形貌与结构进行了相应的表征。以噻吩/正庚烷混合物作为模拟汽油体系,研究了所制备AC-PEG杂化膜的渗透汽化脱硫性能。研究表明,填充活性炭后,膜的脱硫性能明显提高。当活性炭填充量为5%,温度为85℃时,与未填充的PEG膜相比,AC-PEG/PVDF杂化膜的渗透通量由0.43 kg·(m2·h)-1提高至1.14 kg·(m2·h)-1,富硫因子由7.29提高至9.47。
