“…The current investigation is a part of a European Union's Horizon 2020 research and innovation program under the grant agreement No 727463 with the project name "BioMates" [10]. In the first part of the project, the upgrading of fast pyrolysis bio-oil via hydrotreatment was investigated [20]. Within the current research, the potential of the upgraded bio-oil (BioMates) as a suitable intermediate feed for coprocessing with a petroleum fraction in a typical refinery for hybrid fuel production was examined.…”

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.

“…16 The chemical composition and stability of biooil are complex and poor, so it cannot be directly used in internal combustion engines. 17 Compared with the above two pathways, hydrolysis technology can convert biomass into valuable chemicals under relatively mild conditions (<200°C), thus showing a significant advantage. 18 As shown in Fig.…”

Levulinic acid (LA), a class of important chemical intermediates and new energy chemicals, has been considered one of the top-12 platform compounds that can be converted from biomass resources. Substantial progress on the conversion of lignocellulose biomass to LA and the further conversion of LA to high value downstream chemicals have been achieved recently. This review summarizes the preparation and separation processes of LA firstly, and then, emphatically discusses the catalytic system for LA conversion to valuable downstream products, including levulinate esters, 2-methyl tetrahydrofuran (MTHF), Gammavalerolactone (GVL), 5-aminolevulinic acid (DALA), and diphenolic acid (DPA). An outlook is provided at the end of this paper to highlight the challenges and opportunities for the comprehensive utilization of lignocellulose biomass.
