“…36 The bio-gas yield decreases at first and then gradual increases, which is similar to the literature published by Zhao et al reporting the NaCl catalytic pyrolysis of rice husk. 19 The bio-gas yield is larger than that the work of pyrolysis of Eupatorium adenophorum reported by Meng et al 37 Compared with bio-gas yield of non-catalyst pyrolysis, the biogas yield decreases around 5.87% at 3 wt% KOH. The bio-char yield changes a little as catalyst-biomass ratio increases.…”

“…18 Besides, the use of catalyst could control the distribution and property of pyrolysis product. 19 Bu et al have reported that bio-oil had as high as the 74.61% and 74.77% the phenols using two different kinds of activated carbons as the pyrolysis catalyst, respectively. 20 Besides, Wu et al found that the catalytic pyrolysis could contribute to producing more bio-gas and increasing the hydrogen content in the bio-gas.…”

Eupatorium adenophorum, global exotic weed, is used as feedstock in the presence of two catalysts to produce renewable biofuels and green chemicals combining with the advantage of microwave heating and catalytic pyrolysis. The effect of catalyst on yield of pyrolysis products is studied. And the pyrolysis product produced from with and without catalytic pyrolysis is analyzed for performance comparisons. The results show that catalytic pyrolysis tends to produce more bio‐oil and less bio‐gas. The bio‐oil from catalytic pyrolysis has more alkane and ketone, and less carboxylic acid compound compared to non‐catalytic pyrolysis, indicates that catalytic pyrolysis could upgrade the quality of bio‐oil. Compared to bio‐gas of non‐catalytic pyrolysis, the catalytic pyrolysis has larger CO and less CO2 content, particularly for Sodium chloride (NaCl) catalyst pyrolysis. The bio‐char of NaCl catalytic pyrolysis has higher Brunauer–Emmett–Teller (BET) surface area and total pore volume. The above analysis indicates that catalysts pyrolysis makes the properties of pyrolysis product tend to good tendency.

“…At peak 6 (4397 cm -1 (2274 nm)) and 7 (4254 cm -1 (2351 nm)) corresponded to O−H stretch/C−O stretch combination and CH2 bend second overtone of cellulose [29], respectively. The peaks of cellulose and lignin occurred because the major component of rice husk consists of highest cellulose (34.56 %), medium lignin (24.53 %), and lowest hemicellulos (23.54 %) [30].…”

Rice husk is the significant waste residue to be used as renewable energy. The growth of the use on rice husk for generating electricity lead to the verification of its properties. This research aimed to predict higher heating value (HHV), lower heating value (LHV), and ash content (A) of rice husk using Fourier Transform near infrared (FT-NIR) spectroscopy. Rice husk samples used in this experiment were collected from variable areas in Thailand in order to improve the model and get the robust model. The models were built using partial least squares (PLS) regression and validated by unknown sample collected from different area to calibration set. The prediction of HHV, LHV and A were represented the root mean square error of cross validation (RMSECV) of 119 J/g, 119 J/g, and 0.859%wb, respectively. The calibration model can predict the unknown sample successfully with the relative standard error of prediction (RSEP) of 1.104 %, 1.159 %, and, 5.975 %, which implied good performance of NIR model for future prediction. The results suggested that HHV, LHV, and A models should be able to assess the properties of rice husk samples and showed that NIR was reliable and suitable method for combustion system to screening material.

“…The results showed that sodium sulfate accelerated the pyrolysis reaction rate and yielded more bio-oil than non-catalyst. Zhao et al [17] studied the catalytic pyrolysis of rice with sodium chloride and found the liquid yield increased by 3.8% compared with the non-catalytic pyrolysis, and the organic acid content decreased. In summary, all of sodium salts have different effects on the catalytic pyrolysis of biomass.…”

Catalytic pyrolysis of pine sawdust with five sodium salts‐supported γ‐Al2O3 was performed in a fixed‐bed reactor at 500°C for liquid products. The liquid products were analyzed for its physics and chemical properties, such as product yield, oil phase proportion and yield, water content, chemical composition, elemental analysis, and calorific value. The results indicate that liquid yields decreased with the five catalysts compared with non‐catalytic pyrolysis, whereas phase separation (oil and aqueous phases) was observed. The oil phase water content drops sharply to around 10% compared to non‐catalytic bio‐oil (30%). The acid was not observed in the chemical composition of the oil phase product when the catalysts were present. The oxygen content of the oil phase products was significantly reduced. Of the five catalysts, Na2SiO3/γ‐Al2O3 catalyst showed better catalytic performance for its maximum oil phase product yield and oil quality. High heat value of the five oil phase products was all above 30.0 MJ/kg with this catalytic system. The new sodium ion species generated from the combination of sodium salts and γ‐Al2O3, which may be responsible to the improvement of bio‐oil quality. Furthermore, the excess sodium salts on the γ‐Al2O3 surface play an important role on the fast pyrolysis of pine sawdust. © 2019 American Institute of Chemical Engineers Environ Prog, 38:e13146, 2019
