在这项工作中，果肉的超临界水气化是在 Ru/C 催化剂存在下在间歇式反应器中进行的。研究了温度（673–873 K）、时间（0–60 分钟）、生物质比例（2.5–10wt.%）和催化剂比例（0–40wt.%）等反应参数对气体产物组成和气化效率的影响。温度对果肉气化有显着影响；即，随着温度从 673 K 增加到 873 K，氢的量增加了大约四倍。最大氢产量为 54.8 mol H2/kg 果肉，生物量比为 2.5%。对不同反应温度和生物质比下的 SCWG 系统进行热力学平衡分析。将数值结果与实验数据进行比较，以验证所提出的计算模型。比较结果非常一致，表明该模型准确地代表了 773 K 以上温度下的实验结果。
In this work, supercritical water gasification of fruit pulp was conducted in a batch reactor in the presence of Ru/C catalyst. Reaction parameters such as temperature (673–873 K), time (0–60 min), biomass ratio (2.5–10wt.%) and catalyst ratio (0–40wt.%) on the composition of the gas products and gasification efficiency were investigated. Temperature has a significant effect on the gasification of fruit pulp; i.e the amount of hydrogen increased approximately over four times with an increment of temperature from 673 to 873 K. Maximum hydrogen yield was obtained as 54.8 mol H2/kg fruit pulp with a biomass ratio of 2.5%. The thermodynamic equilibrium analysis of the SCWG system was performed for different reaction temperatures and biomass ratios. The numerical results were compared with the experimental data to validate the proposed computational model. The comparisons are in good agreement showing that the model represents the experimental results accurately at temperatures above 773 K.
