“…Higher furfural yield can be obtained at higher acid concentrations and elevated reaction temperatures. The maximum furfural yield at 5% acid concentration (4 g/L) is significantly higher than at 1% acid concentration (1.2 g/L) during the hydrolysis of wheat straw (Guerra et al 2012). The actual maximum yield of furfural is in between 23 and 30% based on the maximum conversion of pentosans (xylan and araban) in the raw material and different reaction conditions (Abad et al 1997;Aguilar et al 2002;TellezLuis et al 2002;Rodriguez-Chong et al 2004;Guerra et al 2012).…”

“…Satisfactory results have been obtained using these assumptions for modeling biomass hydrolysis reactions. There are various kinetic models and mechanisms describing the acid catalyzed hydrolysis of lignocellulosic biomass (Abad et al 1997;Aguilar et al 2002;Tellez-Luis et al 2002;Rodriguez-Chong et al 2004;Keikhosro et al 2006;Guerra et al 2012). During dilute acid hydrolysis of biomass, hemicellulose is easily hydrolyzed due to its amorphous branched structure.…”

“…Furfural can be produced from the acid hydrolysis of pentosans, which are contained in most agricultural residues, such as eucalyptus (Abad et al1997), rice hull (Hector et al 1998), rice straw (Keikhosro et al 2006), corn stover (Qiang et al 2011), wheat straw (Guerra et al 2012), and sorghum straw (Tellez-Luis et al 2002). H2SO4 (Hector et al 1998;Tellez-Luis et al 2002;Keikhosro et al 2006;Guerra et al 2012), CH3COOH (Abad et al 1997), HCl (Herrera et al 2003), andHNO3 (Rodriguez-Chong et al 2004) are the commonly used acids for biomass hydrolysis.…”

Biomass type, reaction temperature, and reaction time play a crucial role on the final yield of furfural.…”

Kinetic Studies on Pisum sativum Waste (Pea pod) Hydrolysis to Furfural

To obtain a higher furfural yield from Pisum sativum (pea pod) waste, the effects of the process variables phosphoric acid concentration (wt.%), reaction temperature, and liquid solid ratio (LSR) were investigated. A new reaction scheme was proposed consisting of series and parallel reactions for the formation of furfural. Kinetic models were developed to describe changes in the concentration of furfural with time. A modified Arrhenius equation was used to find out correlations between kinetic coefficients and reaction parameters. A maximum furfural concentration of 5.27 g/L (40.6% yield based on total conversion of pentosans) was obtained using 6% (wt.%) H3PO4 and liquid-to-solid ratio of 1:10 at 160 °C. Reaction parameters such as acid concentration, reaction temperature, and liquid solid ratio had a strong effect on the yield of furfural.

The aim of this study is to evaluate the potential of some selected biomass waste to be used as feedstock in the production of bioethanol and biohydrogen along with chemicals in Brazil. The substrates are rice bran (RB), rice husk (RH), brewer's spent grain (BSG), soybean waste (SW), and wheat waste (WW). These substrates are treated by diluted acid hydrolysis in an autoclave under different conditions of acid concentration, temperature, reaction time, and moisture. The highest concentration of reducing sugars (RS) of RH, RB, BSG, SW, and WW hydrolysates, measured by the 3,5-dinitrosalicylic acid method (DNS), is 118.16 ± 2.85, 170.39 ± 20.47, 600.97 ± 23.05, 80.38 ± 2.39, and 228.04 ± 3.97 g RS kg −1 substrate (dry basis), respectively. Total sugar concentration (cellobiose, glucose, xylose, arabinose) in the RH, RB, BSG, SW, and WW hydrolysates (with highest concentration of RS) is 56.54 ± 3.65, 42.99 ± 0.84, 72.18 ± 2.34, 42.48 ± 0.18, and 78.03 ± 3.06 g sugar kg −1substrate (dry basis). The total potential of bioethanol and biohydrogen production from the biomass assessed is 199.61 million L per year and 96.14 million m 3 per year, respectively. Therefore, the assessed biomass is proved to be a potential biorefinery feedstock.
