Abstract

Membrane based purification of crude glycerin is of unique importance due to its vast applications in pharmaceutical, polymer and food industries. Polyether Sulfone/Cellulose Acetate Based Mixed Matrix Membranes being reinforced with modified activated carbon has shown enough capability to purify crude glycerin. The membrane is synthesized by phase inversion method by using N-Methyl-2-pyrrolidone (NMP) as solvent and aminopropyl-triethoxycyclene as crosslinker. After adding modified activated carbon as a filler, the membrane is characterized using Fourier Transform Infrared (FTIR) spectroscopy and Thermal Gravimetric Analysis (TGA) to determine the chemistry and mechanical strength of the created membrane, respectively. All membranes' glycerin rejection is investigated using dead end filtration apparatus operating at two bar pressure. The impact of modified activated carbon is also examined by adjusting the filler concentration in a pure mixed matrix membrane solution. As a result, it is noted that the greatest glycerin rejection of 72.7% is achieved at 0.6% weight percentage of activated carbon. Nonetheless, at 0.8% weight of filler, a maximum water flux of 17.8 kg/hr.m2 was attained.
