“…These results were similar to those obtained by other studies using alkaline pretreatment for bioethanol production. Fernandes et al (2015) investigated the steam explosion pretreatment (235°C, 3.2 MPa, and 1 min) and alkali extraction (2% NaOH and 15 min) using cardoon to produce ethanol by SSF. The ethanol concentration and the ethanol yield were 18.7 g/L and 66.6%, respectively.…”

“…In the 1980s, Iotech Corporation researched about steam explosion's effects on the hydrolysis of the puffed lignocellulose biomass. According to Iotech, the optimal conditions for steam explosion of natural lignocellulose were 500-550 psi with retention time of 40 seconds [9]. Shultz et al also investigated the efficiency of steam explosion pretreatment on a variety of lignocellulosic biomass, such as hardwood chips, rice husk, corn straw, and sugar cane [10].…”

An overview of the basic technology to produce bioethanol from lignocellulosic biomass is presented in this context. The conventional process includes two main steps. First, lignocellulose must be pretreated in order to remove lignin and enhance the penetration of hydrolysis agents without chemically destruction of cellulose and hemicellulose. Second, the pretreated material is converted to bioethanol by hydrolysis and fermentation. Some typical published studies and popular processing methods in attempts to improve the biomass conversion to bioethanol and increase the cost-effectiveness are also introduced briefly. Herein, the refinery of the resulted raw bioethanol mixture to obtain higher concentrated solution is not regarded.

“…However, the cost of the enzymatic hydrolysis is significantly higher than acid hydrolysis [30,31]. Moreover, studies about enzymatic hydrolysis have been successfully done using various forms of treated biomass such as corn stover, rice straw [32], rice hull [33], sugarcane bagasse [34][35][36], and palm empty fruit bunch (PEFB) [37][38][39]. Different researchers have used different pretreatment processes and optimization to produce bioethanol from different feedstocks.…”

This study aimed to observe the potential of solid bioethanol as an alternative fuel with high caloric value. The solid bioethanol was produced from liquid bioethanol, which was obtained from the synthesis of oil palm empty fruit bunches (PEFBs) through the delignification process by using organosolv pretreatment and enzymatic hydrolysis. Enzymatic hydrolysis was conducted using enzyme (60 FPUg−1 of cellulose) at a variety of temperatures (35 °C, 70 °C, and 90 °C) and reaction times (2, 6, 12, 18, and 24 h) in order to obtain a high sugar yield. The highest sugars were yielded at the temperature of 90 °C for 48 h (152.51 mg/L). Furthermore, fermentation was conducted using Saccharomyces cerevisiae. The bioethanol yield after fermentation was 62.29 mg/L. Bioethanol was extracted by distillation process to obtain solid bioethanol. The solid bioethanol was produced by using stearic acid as the additive. In order to get high-quality solid bioethanol, the calorific value was optimized using the response surface methodology (RSM) model. This model provided the factor variables of bioethanol concentration (vol %), stearic acid (g), and bioethanol (mL) with a minus result error. The highest calorific value was obtained with 7 g stearic acid and 5 mL bioethanol (43.17 MJ/kg). Burning time was tested to observe the quality of the solid bioethanol. The highest calorific value resulted in the longest burning time. The solid bioethanol has a potential as solid fuel due to the significantly higher calorific value compared to the liquid bioethanol.
