Featuring functional component groups of sustainable solid waste material on carbon dioxide capture

Abstract

The abundant biomass from palm oils can be converted into valuable product via pyrolysis process. In this research, the pyrolysis of sustainable oil palm solid waste, empty fruit bunch (EFB), was performed using a static batch reactor in a tubular furnace. The bio-solid waste material obtained was treated with hydrophobic solution (methyl ester) and then impregnated with bio-oil substrate obtained from the pyrolysis. The modified bio-solid waste material was then tested for carbon dioxide capture. SEM results indicated presence uniform and sticky-like material on the surface when further treated with bio-oil substrate. Though, TGA results indicated that addition of hydrophobic solution and bio-oil reduced the thermal stability of the EFB bio-solid. At higher temperature of 150 - 350°C bio-oil impregnated sample indicated little amount of volatile components with carbon residue of 85.39%. The FTIR results of the hydrphobic impregnated bio-solid waste indicated a unique broad peak among all the samples at 620.05cm -1 which shows the presence of bending stretch carbon dioxide. This shows that bio-oil modified bio-solid char obtained from EFB has the capabity of capturing CO 2.
