Decomposition of oil palm fruit press fiber (FPF) to various liquid products in subcritical water was investigated using a high-pressure autoclave reactor with and without the presence of catalyst. When the reaction was carried in the absence of catalyst, the conversion of solid to liquid products increased from 54.9% at 483 K to 75.8% at 603 K. Simultaneously, the liquid yield increased from 28.8% to 39.1%. The liquid products were sub-categorized to bio-oil (benzene soluble, diethylether soluble, acetone soluble) and water soluble. When 10% ZnCl(2) was added, the conversion increased slightly but gaseous products increased significantly. However, when 10% Na(2)CO(3) and 10% NaOH were added independently, the solid conversion increased to almost 90%. In the presence of catalyst, the liquid products were mainly bio-oil compounds. Although solid conversion increased at higher reaction temperature, but the liquid yield did not increase at higher temperature.
使用高压釜式反应器，在有催化剂和无催化剂的情况下，研究了油棕果压榨纤维（FPF）在亚临界水中分解为各种液体产物的情况。当反应在无催化剂的情况下进行时，固体转化为液体产物的转化率从483K时的54.9%增加到603K时的75.8%。同时，液体产率从28.8%增加到39.1%。液体产物被细分为生物油（可溶于苯、二乙醚、丙酮）和水溶性物质。当添加10%的ZnCl₂时，转化率略有增加，但气态产物显著增加。然而，当分别添加10%的Na₂CO₃和10%的NaOH时，固体转化率增加到近90%。在有催化剂的情况下，液体产物主要是生物油化合物。尽管在较高反应温度下固体转化率增加，但在较高温度下液体产率并未增加。
