“…As shown in Table 1, only a little phenol was generated from pyrolysis of pure poplar with an unsatisfactory yield of 0.49 wt% and a selectivity of 1.47%, which was entirely in accordance with the previous research (Zhang et al, 2019). With the impregnation of NH 4 H 2 PO 4 , the phenol yield as well as the corresponding selectivity was increased dramatically.…”

“…Besides, during the pyrolysis, NH 4 H 2 PO 4 could act as a donor of hydrogen for biomass (Zeng and Bernstein, 2019). As confirmed in previous literatures (Lu et al, 2018c;Zhang et al, 2019), the hydrogen source would exhibit positive effects on the formation of phenol by removing the substitutes on the aromatic rings. Furthermore, the co-pyrolysis of NH 4 H 2 PO 4 and poplar could generate abundant P-containing functional groups, like -O-P-C-, -C-P=O, and so on (Zhang et al, 2018b), which could improve the formation of phenol from non-lignin constituents, viz.…”

“…Currently, only limited researches have been performed on the selective preparation of phenol. Our group put forward a creative method to obtain phenol from catalytic decomposition of biomass by impregnation of K 3 PO 4 or blended with magnetic K 3 PO 4 /Fe 3 O 4 solid catalyst under hydrogen atmosphere (Lu et al, 2018c;Zhang et al, 2019). The phenol yields reached 5.3 and 4.3 wt%, respectively, both with excellent selectivity of ∼18%.…”

“…The phenol yields reached 5.3 and 4.3 wt%, respectively, both with excellent selectivity of ∼18%. The hydrogen source in the pyrolysis process facilitated the elimination of substitutes of phenolic compounds to generate phenol (Liu et al, 2014;Zhang et al, 2019). Differed from conventional techniques to produce phenol from lignin, Zhang et al (2018a) established a new and unique system to selectively produce phenol from non-lignin materials, such as cellulose.…”

A new method was proposed for polygeneration of phenol and supercapacitor electrode material from pyrolysis of biomass impregnated with ammonium dihydrogen phosphate (NH 4 H 2 PO 4). The pyrolysis experiments were executed to demonstrate the product distributions under different NH 4 H 2 PO 4-to-poplar (PA-to-PL) ratios and pyrolysis temperatures in a lab-scale device. The results revealed that the phenol yield attained its optimal value of 4.57 wt% with a satisfactory selectivity of 20.09% at 500 • C under PA-to-PL ratio of 0.6. The pyrolytic solid product obtained at this condition was then subjected to high temperature activation directly without additional activators to prepare N and P co-doped activated carbon (NPAC) as supercapacitor. The physicochemical analysis of NPAC showed that the N and P contents in NPAC reached 3.75 and 3.65 wt%, respectively. The electrochemical experiments executed in a three-electrode system indicated that the NPAC exhibited promising electrochemical performance with a satisfactory capacitance of 181.3 F g −1 at 1 A g −1 .

“…Scholars have found that alkaline additives were beneficial to the thermal cracking of lignin to form monophenolic compounds. Some strong basic solids could effectively promote the deoxygenation of methoxyl (Zhenxi et al, 2019). The second was that mesoporous materials (dolomite and red mud) have a relatively high specific surface area and porosity, which could provide favorable spatial configuration for macromolecular reactions.…”

Corn stover can be converted into a high market value product via catalytic fast pyrolysis. Specifically, through thermochemical conversion, corn stover can be converted into biocrude oil with a high content of unstable phenols, most notably active phenols, which can readily react with aldehydes to form phenolic resins. Therefore, the higher the content of active phenols, the greater the economic value of biocrude oil. This is due to the potential for active phenols to serve as value-added compounds in the form of phenolic resins. Catalysts can be incorporated to improve the reaction rate and product quality during fast pyrolysis. In this study, the effects of three solid catalysts, dolomite, red mud and HZSM-5(25), on the production of active phenols were investigated. The Folin-ciocalteu (FC) method and gas chromatography-mass spectrometry (GC-MS) were utilized to quantify and classify the types of phenolic derivatives present within the bio-oil. The results showed that active phenols with a content exceeding 70% constituted the largest fraction of the phenol derivatives. The formation of active phenols, especially B-phenols, was enhanced by the incorporation of the catalysts HZSM-5, red mud and dolomite. HZSM-5 and dolomite exhibited the best catalytic effect on the production of A-phenols and B-phenols, respectively. The highest content of C-phenols (47.16%) was achieved when red mud was utilized as a catalyst. With regard to the total content of active phenol derivatives, the catalytic effect of dolomite was better than that of HZSM-5 and red mud. The content of total phenols and active phenols increased as the reaction temperature increased from 450 to 600 • C.
