Abstract

Animal biomass wastes and aquatic biomass are alternative biomass materials for renewable energy production which are contained low or no lignocellulosic. Protein is one of major contents in food waste, animal matter, and algae. The 2 selected amino acids, glutamic acid and arginine, were chosen to determine the gasification characteristics. Aqueous solution 1.0 wt% of those two amino acids was gasified under supercritical water conditions by using a tubular flow reactor. Reaction temperatures were varied ranging between 500 and 650 oC and pressure was fixed at 25 MPa. Aqueous feedstock flow rate also fixed at 2.0 g/mL for a residence time of 86-119 s. Identification and quantification of the gas products were examined by gas chromatography (GC). The aqueous phase product was also determined the dissolved carbon by the total organic carbon (TOC) analyzer. An increasing reaction temperature improved the carbon gasification efficiency. The gasification rate of glutamic acid and arginine follow Arrhenius behaviors and are explained well by the first order kinetics equation. Gasification characteristics of glutamic acid and arginine were also compared to those of glycine and alanine. The effect of the functional group in arginine is an increasing alkalinity that made pH of liquid products are above 9.
