Bio-oils and diesel like fuel derived from alkaline treated empty fruit bunch (EFB)ud

摘要

In this work, EFB was chemically pretreated with different sodium hydroxide (NaOH) concentration. Pyrolysis was conducted in the presence of HZSM-5 after the pretreatment step to assess the efects of pretreatment process on bio-oil production. Conversions of EFB were reported to be 61 wt%, 47 wt% and 42 wt%, after pretreatment with 5 wt%, 15 wt% and 25 wt%, NaOH concentrations, respectively. Furthermore, the pretreatment has efectively improved the bio-oil quality by reducing or even eliminating undesired products. Besides, biomass structure was dissembled and converted to valuable compounds after upgrading the bio-oil with improved quality.ud
