The gasification characteristics of aminobutyric acid and serine were determined under supercritical water conditions using a tubular flow reactor. A 1.0 wt% aqueous solution of these two amino acids was gasified at temperatures ranging from 400 to 650 and a pressure of 25 MPa with residence time of 86-222 s. The products were identified and quantified by gas chromatography, and the total organic carbon in the aqueous phase was also determined. The gasification characteristics were compared with those of glycine and alanine. The carbon gasification efficiency increased with higher reaction temperature. The gasification rate followed first order kinetics and was explained well by the Arrhenius equation. The gasification rate of aminobutyric acid was similar to that of glycine and alanine but the gasification rate of serine is faster. The oxygen in the hydroxyl group of serine is highly electronegative, so serine is more reactive than glycine and alanine.

“…However, it was recently reported that the effectiveness of this catalyst differs from feedstock to feedstock. It has been found to be effective for glucoseand cellulose-containing feedstocks, but quite limited for fermentation residue 31) . It is therefore extremely important to find out for which biomass materials the activated carbon catalyst is effective; however, there has so far been no report on a systematic investigation to achieve this.…”

“…The effect of activated carbon was found to be negligible, indicating that this particular catalyst is not effective for enhancing the supercritical water gasification of glycine. Matsumura et al 31) classified biomass feedstock into three groups in terms of the effect of activated carbon: high cellulose content, low cellulose content, and lignin-containing, among which the low cellulose content group was not affected by the activated carbon catalyst. Glycine does not include cellulose or lignin, and so is most suited to the low (or no) cellulose content group.…”

Aqueous solutions (1.0-5.0 wt%) of glycine, which is a model compound of proteins, was gasified in supercritical water using a tubular reactor at temperature of 500-650 ℃ and pressure of 25 MPa for a residence time of 63-188 s. Activated carbon (0.5 wt%) was employed as a catalyst in order to improve gasification efficiency. The identification and quantification of gaseous products were conducted and the total organic carbon was measured for the liquid effluent. Based on the experimental results, the reaction rate parameters were determined for the carbon gasification efficiency of glycine in supercritical water, assuming a first-order reaction. The results showed that an elevated temperature would be required for achieving high carbon gasification efficiency. The activated carbon catalyst was found to be ineffective for glycine.

“…Supercritical water gasification is suitable for the conversion of wet biomass into hydrogen-rich gas because water is a reaction medium, and thus no drying process is necessary. Furthermore, water is safe, non-toxic, and cheap 6), 7) . Hence, tomato residue in this area can be considered a good feedstock for supercritical water gasification.…”

In this study, we focus on the use of tomato residue produced in the rural area of Kita-Hiroshima, Hiroshima, Japan as a feedstock for gas production via supercritical water gasification (SCWG). Calculation was made based on the amount of tomato residue produced in this area. The process was designed based on consideration of the energy recovery achieved with a heat exchanger network. The reactor temperature and pressure were set at 600 and 25 MPa, respectively. The process efficiency was calculated based on thermodynamics. The potential of tomato residue for gas production was evaluated from the perspective of energy, economics, and environmental impact. As a result, the net produced energy was calculated as 10.45 MJ/kg-feedstock from SCWG of tomato residues feedstock. In total, annual amount of tomato residues can produce energy to supply 76 MWh of electricity with a carbon dioxide reduction of 13.6 t.
