“…[2] However, bio-oil is a thermodynamic non-equilibrium product, [3] so that it contains many reactive oxygenated components which result in polymerization and low heating value. [4] Most notably, bio-oil possesses strong corrosiveness because it contains up to 30 wt % of carboxylic acids, thus not suitable for direct application in the internal combustion engine. [5] Although many approaches have been taken to improve the quality of bio-oil, the intrinsic acidic nature of bio-oil still poses a major problem and challenge.…”

In this work, Red Mud, an alkaline solid waste from alumina production, was used as neutralizing agent to convert carboxylic acids in bio‐oil into ketones. The total acidity of the bio‐oil decreased significantly from 152.60 to 0.63 mg KOH/g, while the high heat value boosted from 17.25 to 29.57 MJ/kg. Meanwhile, the leachable alkalinity of Red Mud declined from 65.34 to 3.02 mg HCl/g, mitigating the harmfulness and perniciousness to the environment. Furthermore, characterizations of XRD, XPS and 57Fe Mössbauer spectroscopy indicated that the weak magnetic iron species in Red Mud was completely transformed into stronger magnetic Fe3O4. With magnetic separation the iron recovery reached up to 91.96 % with iron grade of 65.83 %, which is up to the standard of steelmaking raw material. The findings in this research not only open avenue for valorization of bio‐oil but also help explore the resourceful utilization of Red Mud.

“…Zerva et al [10] studied the HDO of phenol and biomass fast pyrolysis oil over 10% Ni/ZrO 2 and 10% Ni/WO 3 -ZrO 2 catalysts. The study was performed in a fixed bed reactor under mild conditions of 435 psig H 2 pressure and temperatures from 50-250 • C. The results showed that the Ni/ZrO 2 catalyst achieved a 100% conversion and maximum selectivity at 110 • C towards cyclohexanol in the phenol HDO experiments.…”

A process simulation model was created using Aspen Plus to investigate the hydrodeoxygenation of 4-propylguaiacol, a model component in lignin-derived pyrolysis oil, over a presulphided NiMo/Al2O3 solid catalyst. Process simulation modelling methods were used to develop the pseudo-homogeneous packed bed microreactor. The reaction was conducted at 400 °C and an operating pressure of 300 psig with a 4-propylguaiacol liquid flow rate of 0.03 mL·min−1 and a hydrogen gas flow rate of 0.09 mL·min−1. Various operational parameters were investigated and compared to the experimental results in order to establish their effect on the conversion of 4-propylguaiacol. The parameters studied included reaction temperature, pressure, and residence time. Further changes to the simulation were made to study additional effects. In doing so, the operation of the same reactor was studied adiabatically, rather than isothermally. Moreover, different equations of state were used. It was observed that the conversion was enhanced with increasing temperature, pressure, and residence time. The results obtained demonstrated a good model validation when compared to the experimental results, thereby confirming that the model is suitable to predict the hydrodeoxygenation of pyrolysis oil.
