摘要

In this study, high-pressure hydrothermal processing of different biomass sources and products, which include cellulose, xylan, lignin, pine wood, paper waste, and waste lignin was performed at 200-275 ℃ in presence of MSO_4 catalyst. Biomass slurry was prepared in distilled water containing NiSO_4, loaded in a high-temperature high-pressure reactor and heated to different temperatures. The reaction was continued for 120 min and during the reaction gas samples were withdrawn and analyzed using Chrompack capillary column on the gas chromatograph equipped with thermal conductivity detector. The analysis of gas samples revealed the presence of H_2, CO_2, CO, and CH_4 gases. Increase in catalyst concentration from 3 wt% to 10 wt% has significantly increased the H_2 generation. Absence of catalyst, however, generated almost negligible amount of H_2. Among the biomass sources and products investigated here, xylan has yielded maximum amount of H_2. The liquid samples were analyzed by high-performance liquid chromatography (HPLC) and Fourier transform infrared (FTIR) spectroscopy which revealed the presence of sugars along with the other intermediates.
