Fast pyrolysis is envisioned as a promising technology for the utilization of forestry wood waste (e.g., widely available from tree logging) as resources. In this study, the potential of an innovative approach was explored to convert forestry wood waste of Vernicia fordii (VF) into energy products based on fast pyrolysis combined with nano-catalysts. The results from fast pyrolysis using three types of nano-catalysts showed that the distribution and composition of the pyrolytic product were affected greatly by the type of nano-catalyst employed. The use of nano-Fe2O3 and nano-NiO resulted in yields of light hydrocarbons (alkanes and olefins) as 38.7% and 33.2%, respectively. Compared to the VF sample, the use of VF-NiO and VF-Fe2O3 led to significant increases in the formation of alkanes (e.g., from 14% to 26% and 31%, respectively). In addition, the use of nano-NiO and nano-Fe2O3 catalysts was found to promote the formation of acid, aromatics, and phenols that can be used as chemical feedstocks. The NiO catalyst affected the bio-oil composition by promoting lignin decomposition for the formation of aromatics and phenolics, which were increased from 9.52% to 14.40% and from 1.65% to 4.02%, respectively. Accordingly, the combined use of nano-catalysts and fast pyrolysis can be a promising technique for bio-energy applications to allow efficient recovery of fuel products from forestry wood waste.

“…Then, the aqueous solution of iron (III) nitrate nonahydrate was introduced into Ni/HZSM-5 catalyst slowly and the catalyst was kept overnight in a desiccator and dried at 120 o C for 12 h in the oven. After being dried, the powder catalyst was calcined in 550 o C in the air for 3 h and reduced in flowing H2 at 550 o C for 2 h, as reported in the previous study [13]. The Ni-Fe/HZSM-5 catalyst was obtained with different metal ratio of 1:1 and 1:2 for nickel-iron.…”

“…However, when compared with HZSM-5 catalyst, the peak intensity of Ni-Fe/HZSM-5 catalyst decreased. It may be the incorporation of Ni and Fe on the HZSM-5 supports decreased the degree of crystallinity of the HZSM-5 as a support [13]. Figure 3 shows the surface morphologies of the HZSM-5, 5 % (Ni-Fe)/HZSM-5, and 10 % (Ni-Fe)/HZSM-5 catalyst.…”

“…When the molar ratio of Ni to Mo was 0.5, the highest hydrocarbon fuel yield was about 50 % [12]. Catalytic fast pyrolysis of biomass with Fe/HZSM-5 catalyst was showed the yields of aromatic hydrocarbons were significantly increased with the rising of temperature from 500 o C to 600 o C and decreased with the increase from 600 o C to 800 o C. It was reported that the addition of transition metals into HZSM-5 catalyst was used to reduce the yields of polycyclic aromatic hydrocarbons (PAHs) and improve the amounts of monocyclic aromatic hydrocarbons (MAHs) [13][14][15]. HZSM-5 catalyst was used for the conversion of jatropha oil.…”

In this study, hydrocracking of coconut oil over Ni-Fe/HZSM-5 catalyst was carried out in a batch reactor under different reaction temperature. Coconut oil is proposed as one of the potential feedstock for biofuel production. The Ni-Fe/HZSM-5 catalyst was prepared by incipient wetness impregnation method. The characterization of Ni-Fe/HZSM-5 catalyst by X-Ray Diffraction (XRD), Scanning Electron Microscopy-Energy Dispersive X-ray (SEM-EDAX), and Brunauer-Emmett-Teller (BET). The chemical composition of biofuel was analyzed by Gas-Chromatography-Mass Spectrometry (GC-MS). The results from the GC-MS analysis showed that the hydrocracking reaction over 10 % (Ni-Fe)/HZSM-5 catalyst at temperature of 375 o C obtained the highest hydrocarbon content (contained 49.4% n-paraffin, 26.93 % isoparaffin, 3.58 % olefin) and the highest yield of bio-gasoil 38.6 % in the biofuel liquid hydrocarbon. Pentadecane (n-C15) and heptadecane (n-C17) were the most abundant hydrocarbon compounds in biofuel liquid hydrocarbon. Decarboxylation and/or decarbonylation was the dominant reaction pathways in this process. Based on the result, the reaction temperature had a significant effect on the distribution of biofuel composition and yield of biofuel from coconut oil.

“…On the other hand, Sun et al [33] indicated that an application of Fe/ZSM-5 to the fast pyrolysis of wood sawdust conducted using Py-GC/MS increased the efficiency of the production of monocyclic aromatic hydrocarbons (benzene, toluene, ethylbenzene, and xylenes) and decreased the amount of the formed polycyclic aromatic hydrocarbons (such as naphthalenes, phenanthrenes, or anthracenes) in comparison to the ZSM-5 material. They also suggested that the drop in the yield of the polymerization of monocyclic compounds and the decrease in the amount of polycyclic aromatics observed in the case of the Fe-ZSM-5 material suppressed the formation of coke, which is the main reason for catalyst deactivation.…”

Lignocellulosic biomass is one of the most attractive renewable resources that can be used for the production of biofuels and valuable chemicals. However, problems associated with the low efficiency of its conversion and poor selectivity to desired products remain. Therefore, in recent years researchers have focused on the design of highly active and stable catalysts, enabling an increase in the effectiveness of lignocellulosic biomass processing. This work is devoted to the presentation of the latest trends in the studies of the heterogeneous catalysts used in thermo-chemical conversion of such feedstock. The systems applied for the production of both bio-oil and hydrogen-rich gas are discussed. Zeolites, mesoporous materials, metal oxides, supported metal catalysts, and modifications of their structure are described. Moreover, the impact of the physicochemical properties of the presented catalyst on their catalytic performance in the mentioned processes is demonstrated.
