“…Several layouts for the pyrolysis process have also been proposed to reach a global self-sustainable performance from an energetic point of view [3,18,19]. In a previous work developed in our group, both oxygen content and acidity of bio-oils were found to decrease in woody biomass pyrolysis carried out in an Auger reactor when low-cost materials, such as CaO/sand or CaOÁMgO/sand mixtures, were used as both in situ catalysts and heat carriers [20].…”

“…In order to ensure that the composition and properties of model compound and bio‐oil are close, a multicomponent model compound was adopted in this article, which is shown in Table . The overall molecular formula of the multicomponent model compound is CH 1.9 O 0.43, and the content of C, H, and O in the multicomponent model compound is similar to that of bio‐oil …”

“…Therefore, the decentralized biomass fast pyrolysis devices were established and obtained bio‐oil with high energy density, and then bio‐oil was deeply processed, which can reduce the transportation cost of large‐scale processing and utilization of biomass . However, the bio‐oil contains acid, aldehydes, alcohols, ketones, and other oxygenates, leading to low calorific value, low pH, nonvolatility, corrosiveness, thermal instability, and so forth. Moreover, the pyrolysis oil (bio‐oil) contains about 15–30% water, resulting in the bio‐oil into two layers.…”

The combination of steam and CO2 reforming of bio‐oil is proposed in this article. The combined reforming can make good use of the advantages of steam reforming and CO2 reforming. The results indicate that H2 yield, potential H2 yield, and H2/CO were 60.23, 81.97, and 2.77%, respectively, at the condition of 700°C and bio‐oil:CO2:H2O = 1:0.5:1.5. Bio‐oil:CO2:H2O has a significant effect on the H2 yield, potential H2 yield, and H2/CO in the process of combined reforming. A different ratio of H2/CO can be obtained by adjusting the proportion of bio‐oil:CO2:H2O, which can meet different industry requirements. The results of X‐ray diffraction and scanning electron microscope analyses indicate that the catalyst deactivation was the result of a combination of carbon deposition and Ni grain sintering, and the carbon deposition was a main reason for the catalyst deactivation.

In the present study, thermogravimetric analysis was used for investigation a bagasse pyrolysis. Multi‐period models were applied for evaluation of kinetics parameter based on the TG curve. The decomposition bagasse process was undergone four periods via the breakdown of each different chemical component in a sample. The dehydration occurred below 170°C; hemicellulose primarily and cellulose partially decomposed in a range of 170 to 318°C and cellulose continuously decomposed from 318 to 400°C. The temperature range of 400‐700°C for the last period showed the evidence of lignin decomposition. The study also identified activation energy constant (Ea), the pre‐exponential factor (A) and reaction order (n) for each period of pyrolysis process. The dependence of the breakdown of the specific chemical bond on the pyrolysis temperature was also proven by FTIR spectrum analysis.
