Preparation and Characterization of Matrimid-Based Carbon Membrane Supported on Tube for CO₂ Separation

Abstract:

A series of research had been conducted to alter the performance of carbon membranes by manipulating the parameters during the fabrication process. In this study, the effects of carbonization temperature on the performance of carbon membrane were investigated. Matrimid-based carbon membrane supported on ceramic tube was fabricated through the dip-coating technique. The prepared membranes were characterized by using the scanning electron microscopy (SEM) and pure gas permeation test for the study on morphological structure and gas separation performance, respectively. The carbonization process was performed at different carbonization temperatures (600, 700, and 800 ^oC) for the same heating rate of 1 ^oC/min under Ar flow. The increment of carbonization temperature produced carbon membrane with small size of pores. The carbon membrane prepared at 800 ^oC showed the highest CO₂/CH₄ and CO₂/N₂ selectivity of 79.65 and 74.76, respectively.
