“…Doubling the H 3 PO 4 concentration only modestly increased the levoglucosenone contribution (52.79% ± 0.11%). Catalytic pyrolysis of cellulose leads to 1,4:3,6-Dianhydro-α-D-glucopyranose [26] with relative peak areas between 5-15% [15]. DGP is considered an undesired by-product for levoglucosenone production, as it currently has no meaningful applications.…”

“…Understanding the mechanisms involved during the pyrolysis of cellulose is necessary to identify the origin of some of the chemicals present in the lignocellulose pyrolysis biooil. Numerous studies investigated the catalytic pyrolysis of cellulose using two types of catalysts: (1) acidic catalysts such as zeolites, − metal oxides, − and carbonaceous acids − and (2) basic catalysts such as alkali and alkaline earth metal oxides ,,− and metal chlorides. − The acidic catalysts promoted the formation of aromatic compounds, which improved the fuel properties of the biooil. The basic catalyst promoted the formation of high-value chemicals that can be used as building blocks for other commercial chemicals.…”

“…Fast pyrolysis has been proven to be an effective technology that can convert biomass into biooil, biogas, and biochar. , Catalytic fast pyrolysis (CFP) has been gaining more attention because its major product, i.e., biooil, can be coprocessed with standard gas oil to produce fuel . Furthermore, the CFP can promote the production of certain high-value chemicals such as LGO and LGA. , Fluidized bed reactors allow good mixing of the feedstock and catalyst during catalytic fast pyrolysis, which allows good heat transfer into the feedstock particles that are fed into the reactor at a constant feeding rate. In a fluidized bed, attrition phenomena can result in the loss of catalyst particles that exit the reactor due to their reduced size .…”

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.

“…Because of the global energy and environmental issues, development of environment-friendly technology for utilizing sustainable resources is urgently needed ( Shen et al, 2019 ; Qian et al, 2021 ). Lignocellulose, as a predominant natural carbon source with a worldwide distribution, can potentially provide versatile carbohydrate resources.…”

Glycerol waste was combined with microwave to pretreat lignocellulose before fast pyrolysis. After pretreatment, most alkali and alkaline earth metals (87.9%) and lignin (52.6%) were removed, and a higher crystallinity was obtained. Comparatively, glycerol waste combined with microwave was proven to be more efficient than glycerol with conventional heating. During fast pyrolysis, higher content of levoglucosan in glycerol waste–pretreated products (27.5%) was obtained, compared with those pretreated by pure glycerol (18.8%) and untreated samples (5.8%). Production of fermentative toxic aldehyde and phenol by-products was also inhibited after glycerol waste treatment. Following mechanistic study had validated that microwave in glycerol waste solvent could effectively ameliorate structure and components of lignocellulose while selectively removing lignin. Notably, under the optimal condition, the levoglucosan content in pyrolytic products was enhanced significantly from 5.8% to 32.9%. In short, this study provided an archetype to dually utilize waste resources for ameliorating lignocellulose structure and precisely manipulating complex fast pyrolysis.
