摘要

Abstract

Carbon dioxide (CO

) is greenhouse gas which originates primarily as a main combustion product of biogas and landfill gas. To separate this gas

an inside coated thin film composite (TFC) hollow fiber membrane was developed by inter facial polymerization between 1

3-cyclohexanebis-methylamine (CHMA) and trimesoyl chloride (TMC). ATR-FTIR

SEM and AFM were used to characterize the active thin layer formed inside the PSf hollow fiber. The separation behavior of the CHMA-TMC/PSf membrane was scrutinized by studying various effects like feed gas pressure and temperature. Furthermore

the influence of CHMA concentration and TMC concentration on membrane morphology and performance were investigated. As a result

it was found that mutually the CHMA concentration and TMC concentration play key roles in determining membrane morphology and performance. Moreover

the CHMA-TMC/PSf composite membrane showed good CO

/CH

separation performance. For CO

/CH

mixture gas (30/70 by volume) test

the membrane (PD1 prepared by CHMA 1.0% and TMC 0.5%) showed a CO

permeance of 25 GPU and the best CO

/CH

selectivity of 28 at stage cut of 0.1. The high CO

/CH

separation performance of CHMA-TMC/PSf thin film composite membrane was mostly accredited to the thin film thickness and the properties of binary amino groups.
