“…values than those obtained here (Danon et al, 2014, Liu et al, 2014, Jing and Lü, 2007, which suggests that the effect of temperature observed herein is not as high as that reported in other studies. However, results regarding the same temperature range as in the present work led to lower E a , thus in agreement with our findings (Kim et al, 2011).…”

“…In the recent past, the kinetics of FU production / decomposition competitive reactions (Marcotullio et al, 2009) were thoroughly studied for several biomasses or biomass-derived molecules such as wheat straw (Yemiş and Mazza, 2012) and xylose (Liu et al, 2014) submitted to HTC. Most works generally focused either on production or on decomposition reactions separately (Liu et al, 2014, Danon et al, 2014, Kim et al, 2011. Simple consecutive reaction models as well as models taking into account side reactions have been developed Lü, 2007, Liu et al, 2014) and are in agreement with published studies on degradation compounds from sugars (Rasmussen et al, 2014).…”

The main compounds of plant biomass, i.e., cellulose, lignin and hemicellulose, were submitted to hydrothermal carbonisation (HTC) in ranges of temperature and time of 140-240ºC and 0.5-24 h, respectively. Those parameters were combined into a single one, the severity factor, and its effect on hydrochar yield on the one hand, and on pH, yield and composition of the liquid fraction on the other hand, was investigated in depth. The production of furanic and phenolic compounds was correlated with both severity and pH. The kinetics of furfural (FU) and 5-hydroxymethylfurfural (5-HMF) production and consumption were also investigated and modelled, and the results were compared to those reported in the literature. The production of nine phenolic compounds from lignin HTC was also considered.

Hydrothermal conversion (HTC) of sewage sludge (SS) and its relevant model compounds such as cellulose, glucose, lignin and soybean protein (substitute for protein) was experimentally conducted at moderate reaction temperature of 260 °C for 60 min. The structural properties, carbon-containing groups, and microstructure of the char were characterised by several techniques. The results revealed that more benzene rings were formed by small clusters and the CO bond on Aryl-alkyl ether decomposed on the surface particles during the HTC process. In addition, the catalyst Zeolite Socony Mobil-5 (ZSM-5, Si/Al: 300) showed an excellent performance on the high graphite degree of the char under moderate reaction temperature of 260 °C. In particular, cellulose has the most dramatic influence on the depolymerisation of C-(C,H). As evidenced with SEM, the size of the char derived from SS with ZSM-5 catalyst is 10-15μm, which is smaller than the char without catalyst. A mechanism for derivation of char from individual model compounds is proposed. The end products of lignin are composed of polyaromatic char, while the composition of the char derived from protein suggests that polymerisation may occur during hydrothermal reaction leading to formation of structures with N-containing compounds.

“…Furfural is conventionally produced by hydrolysis of a variety of biomass sources including almond shell, sugarcane, and corn with the aid of liquid acid catalysts at high temperatures (200-250°C) (Kim et al 2011). However, liquid acid catalysts are toxic and corrosive, and their applications can generate large amounts of toxic wastes.…”

Factors influencing dehydration of xylose to furfural, such as catalyst and extract agents, were investigated. Results indicated that high-temperature water may substitute for solid and liquid acid as a catalyst, and ethyl butyrate improved furfural yield for the high distribution coefficient. A furfural yield of 75 % was obtained at 200°C for 3 h in ethyl butyrate/water. The reaction kinetics of xylose dehydration to furfural was investigated and it was found that the reaction order was 0.5, and the activation energy was 68.5 kJ/mol. The rate constant k showed a clear agreement with the Arrhenius law from 160 to 200°C.
