“…Based on the XRD results, the prepared iron-modified Ni-Co composite catalyst was mainly composed of metal oxides. It could be conjectured that the catalyst had rich oxygen vacancy on the surface of the catalyst, and oxygen species could combine with intermediates derived from the cracking of organic polymers (Yang et al, 2023). These reactions promoted the formation of ketones in the bio-oil.…”

In this work, the iron-modified Ni-Co composite catalyst was synthesized, and its catalytic effect on product distribution, behaviour and liquid characteristics was deeply studied. The result showed that the synthesized catalyst significantly improved the pyrolysis behaviour of cellulose, and the decomposition of cellulose occurred earlier. The highest yield of liquid product was 56.79wt%, which was obtained by adding the NCF-6 catalyst. The optimal ratio of catalyst in the sample was 5%, and the optimal pyrolysis temperature was 530°C. The characteristics of liquid product showed the introduction of the synthesized catalyst enhanced the decomposition of anhydrosugars and significantly promoted the generation of ketones in the liquid. The highest content of ketones in the liquid was 25.12%. Further analysis showed that the selectivity of 2(5H)-Furanone in the liquid component was strongest. These works provided an effective way to produce ketone-rich bio-oil from biomass.

“…43 Furthermore, no significant loss of activity catalytic was observed after several regenerations of the FRM catalyst. 38 Due to its stable catalytic activity and resistance to poisoning by alkali and alkaline earth metals from the ash in biomass, the FRM is a potential catalyst for the selective pyrolysis of lignocellulosic biomass. Because of the complexity of lignocellulosic biomass, it is necessary to study its major polymers separately to understand their contribution to the pyrolysis products yields and the quality of the biooil.…”

The catalytic pyrolysis of microcrystalline cellulose (CE) using formulated red mud (FRM) and HZSM-5 catalysts was conducted in a fluidized bed reactor at 400 °C. Both catalysts promoted the conversion of CE. The FRM promoted the formation of organic liquids and pyrolytic water, while the HZSM-5 catalyst promoted the pyrolytic water and the formation of pyrolysis noncondensable gases (PNCGs). The electrostatic precipitator (ESP) biooil (25.8 ± 2.54 wt %) from the CE-FRM consisted mainly of levoglucosan (LGA, 68.60 area %), cyclic ketones (CKs, 2.91 area%), and aromatics (1.38 area%), whereas the HZSM-5 biooil consisted of levoglucosan (82.27 area%). The major oxides of the FRM (i.e., Al 2 O 3 and Fe 2 O 3 ) were used during the pyrolysis of CE. Both catalysts promoted the formation of pyrolytic water and PNCGs. Compared to sand, the Fe 2 O 3 promoted the formation of anhydrous sugars by about 6%, aromatics by more than 3-fold and CKs by more than 2-fold, whereas the Al 2 O 3 promoted the formation of noncyclic oxygenates (NCOs) by more than 3-fold, furans by more than 3-fold, CKs by more than 5-fold, and aromatics by more than 28-fold. During the CE-FRM pyrolysis, larger particle size resulted in higher char/coke and pyrolytic water yields and lower organic liquid and PNCGs. This was due to the longer residence time of LGA in the larger particles where further dehydration and charring occur. The pyrolysis of D-glucose (DG) over the FRM catalyst resulted in higher char/coke and water yields and lower organic liquid and PNCGs compared to the catalytic pyrolysis of CE over FRM. Compared to the CE-FRM biooil, the DG-FRM biooil had higher furans content and lower yields of anhydrous sugars and aromatics. The longer residence time of LGA produced during the DG-FRM pyrolysis in the hot zone resulted in its further dehydration and polymerization to form char.
