Bio-oil derived from fast pyrolysis of oil palm empty fruit bunch (EFB) was catalytically reformed inside a stainless steel multichannel tubular reactor using steam and air as reforming agents. The catalyst used, denoted as Fe/AC, was an iron catalyst loaded on the coconut shell-derived activated carbon (AC) prepared by a new approach of impregnating iron from an aqueous solution onto the AC in a stepwise manner. Results indicate that a stepwise impregnation was able to minimise the agglomeration of iron particles on AC surface, allowing high loading of iron onto the AC without severely affecting Fe dispersion and catalyst pore properties. The highly reducible, highly efficient catalyst produced in this study was able to lower the concentration of tar in producer gas to lower than 100 mg/Nm³. The best composition of the burnable product gas was obtained with iron loading of 15 wt%, reaction temperature of 800 °C, steam-to-carbon molar ratio (S/C) of 1.0 and air equivalence ratio (ER) of 0.1, with gas composition of 33.5% H₂, 21.0% CO, 14.0% CH₄, 18.8% CO₂ and 1% C₂ hydrocarbons and a cold gas efficiency of 78.5%.

在不锈钢多通道管式反应器内使用蒸汽和空气作为重整剂，对油棕空果串 (EFB) 的快速热解衍生的生物油进行催化重整。所使用的催化剂，表示为 Fe/AC，是负载在椰壳衍生的活性炭 (AC) 上的铁催化剂，通过一种新方法将铁从水溶液中浸渍到活性炭上，以逐步的方式制备。结果表明，逐步浸渍能够最大限度地减少铁颗粒在活性炭表面上的团聚，允许铁在活性炭上的高负载量，而不会严重影响铁的分散和催化剂孔隙性能。本研究中生产的高度还原、高效的催化剂能够将发生炉煤气中的焦油浓度降低至低于 100 mg/Nm ³. 可燃产物气体的最佳组成是在铁负载量为 15 wt%、反应温度为 800 °C、蒸汽与碳的摩尔比 (S/C) 为 1.0 和空气当量比 (ER) 为 0.1 的情况下获得的，其中33.5% H ₂、21.0% CO、14.0% CH ₄、18.8% CO ₂和1% C ₂烃的气体组成和78.5%的冷气效率。
