Upgrading the characteristics of the bio-oil obtained from rapeseed oil cake pyrolysis through the catalytic treatment of its vapors
2019
Abstract The present work is aimed to investigate the upgrading of rapeseed oil cake pyrolysis bio-oil (PBO) through catalytic treatment of its vapors in a fixed bed reactor. In this regard, HZSM-5 zeolite and promoted Fe 2 O 3 /ZSM-5 samples were prepared. The HZSM-5 zeolite was synthesized by NaOH treatment and then it was used as support material to obtain Fe 2 O 3 -ZSM-5 catalysts (2.5-10 wt% Fe 2 O 3 load) produced by metalorganic chemical vapour deposition (MOCVD). The support material and catalysts prepared were characterized by BET, XRD, SEM, EDX methods. The Fe 2 O 3 -ZSM-5 catalysts were then used in the study on improving the characteristics of the rapeseed oil cake pyrolysis bio-oil through catalytic treatment of its vapors.The results obtained by non-catalytic and catalytic pyrolysis experiments showed that bio-oil yields have decreased in the presence of catalysts. In addition, the bio-oil composition was determined by GC/MS method and it was observed that Fe 2 O 3 /ZSM-5 catalyst lead to a significant improved quality of the pyrolysis bio-oil in comparison with product obtained by non-catalytic process. The catalyst improved the oxygen removal process from the organic phase of pyrolysis bio-oil and further increased the quantity of desirable products such as aromatic and phenolics compounds.
