“…The char had a standard deviation of 0.1%. This yield decreased with all catalysts, especially with 40 ZSM-5 and [4,7,14]. The reason behind this discrepancy is not clear but, we also observed a decrease in bio-oil with ZSM-5 catalysts.…”

“…A maximum LGO yield was obtained at 335°C with the cellulose-to-catalyst mass ratio of 3:2. Further studies confirmed the promising catalytic capabilities of the SO 4 2− /ZrO 2 and SO 4 2− /TiO 2 for LGO production [45,46]. Compared with the liquid acid catalysts, the sulfated metal oxide catalysts are very easy to utilize.…”

Solid phosphoric acid (SPA) catalysts with different carriers were prepared and used for catalytic fast pyrolysis of poplar wood to produce levoglucosenone (LGO), a valuable anhydrosugar derivative that can be used in various organic synthesis applications. Pyrolysis-gas chromatography/mass spectrometry (Py-GC/MS) experiments were performed to evaluate the catalytic capabilities of these catalysts under different reaction conditions. The results indicated that SPA catalyst prepared with the SBA-15 carrier exhibited the best catalytic capability for selectively producing LGO. Both the catalytic pyrolysis temperature and catalyst-to-biomass ratio affected the pyrolytic products greatly. The maximal LGO yield reached as high as 8.2 wt% from poplar wood, obtained at the pyrolysis temperature of 300°C and the catalyst-to-biomass ratio of 1. The by-products during the catalytic pyrolysis process were mainly acetic acid (AA) and furfural (FF). In addition, the SPA catalyst possessed better catalytic capability than the liquid phosphoric acid (H 3 PO 4 ) catalyst to produce LGO.

“…An optimal concentration of sulfuric acid can also be used in lieu of phosphoric acid to improve the yield of levoglucosenone . Solid phosphoric acid, solid acid catalysts, sulfated zirconia, sulfated titania, and other metal oxides are some candidates that can be used for boosting the yield of levoglucosenone through catalytic fast pyrolysis . Further, ionic liquids, and polar aprotic solvents facilitate higher conversion of cellulose to levoglucosenone at optimal temperature, reaction time, and catalyst‐to‐feedstock ratio …”

The cellulosic component of lignocellulosic biomass can be converted to commercially valuable platform chemicals through pyrolysis provided it is effectively controlled and optimized. This review first discusses the underpinning kinetics and mechanism of cellulose pyrolysis to identify target platform chemicals. Platform chemicals like 5‐hydroxymethyl furfural, 5‐chloromethyl furfural, and levoglucosenone, which are potentially amenable to the pyrolytic conversion of cellulose, are then elucidated. There are laboratory and large‐scale reactor technologies available for converting biomass to bio‐oil but they have not been comprehensively investigated for producing platform chemicals through pyrolysis. This review critically evaluates different reactor types available for developing the catalytic pyrolysis process for converting cellulosic component of biomass to platform chemicals. The fluidized bed reactor stands out as the most suitable reactor technology for the catalytic pyrolysis of cellulose to platform chemicals owing to attributes like short residence time, high heating rate, uniform mixing, efficient heat transfer, and scalability of operations. This article provides perspective on the implementation of this technology for the pyrolysis of the cellulosic component of biomass to platform chemicals. © 2019 Society of Chemical Industry and John Wiley & Sons, Ltd
