CARBON FIBER AEROGEL FROM NANOFIBRILLATED CELLULOSE OF SUGARCANE BAGASSE AND WASTE ENGINE OIL RESIDUE FOR OIL SORPTION

Abstract

The oil adsorption method is one of the best approaches that can be used to treat an oil spillage on the water surface. The researchers have moved forwards in developing oil sorbent material that is very efficient for oil adsorption process, environmentally friendly, and very low cost. Following this, combination of two different wastes has been used as raw material to prepare oil sorbent material with such characteristic in this study. Nanofibrillated cellulose were extracted from sugarcane bagasse and were combined with carbon residue from waste engine oil to produce carbon fiber aerogel (CFA). Different ratio of cellulose to waste engine oil residue, WER (between 0.5 until 1.5) at different carbonization temperature (500 to 700?C) was used to develop CFA and the oil sorption capacity was investigated. It was observed that ratio of cellulose to WER 1.5 and carbonization temperature of 600 ?C achieved the highest oil sorption capacity of 5.47 g/g. The sample CFA possess highly fibrous and rough surface structure as observed by FESEM, low density (0.17 g/cm3) with high carbon content (C-C and C?C) as confirmed by the FTIR. This study stimulates an insight to utilize sustainable waste sources as the raw material for oil sorbent material development.
