“…Based on the severity of organosolv pre‐treatment it can hydrolyze about 40–60% of the lignin along with partial amount of hemicelluloses from rice straw to produce cellulose rich pulp . Recently Asadi and Zilouei optimized the organosolv pre‐treatment of rice straw for different temperatures, residence time and ethanol concentration and found that although enzymatic digestibility of pre‐treated rice straw improved by increasing the severity factor but the solid recovery decreased significantly after organosolv. This was due to the solubilization of carbohydrate, lignin, and inhibitor formation.…”

The surplus availability of rice straw, its limited usage, and environmental pollution caused by its ineffi cient burning has fostered research for its valorization to biofuels. This review elucidates the current status of rice straw potential around the globe along with recent advances in revealing the critical factors responsible for its recalcitrance and chemical properties. The role and accumulation of high silica content in rice straw has been elucidated with its impact on enzymatic hydrolysis in a biorefi nery environment. The correlation of different pre-treatment approaches in modifying the physiochemical properties of rice straw and improving the enzymatic accessibility has also been discussed. This study highlights new challenges, resolutions, and opportunities for rice straw based biorefi neries.

“…Biological hydrogen production from crop residues is renewable, whereas hydrogen production from natural gas is not. Asadi and Zilouei () used ethanol organosolv pretreated rice straw to produce biohydrogen. The highest hydrogen yield of 19.73 ml/g straw was obtained at the pretreatment temperature of 180°C for 30 min with the ethanol concentration of 45wt%.…”

Lignocellulosic biomass is one of the potential feedstocks to produce second-generation cellulosic ethanol and biochemicals. To enhance the enzymatic digestibility of lignocellulosic biomass for efficient enzymatic saccharification, a variety of pretreatment methods have been studied. Among these, organosolv pretreatment using ethanol is a promising pretreatment method owing to its inherent advantages, such as low solvent cost, lack of toxicity, the ability to retain most cellulose fraction in substrates for enzymatic hydrolysis, coproduction of high-purity lignin and hemicellulosic sugars, easy solvent recovery, and reuse. In this review, the research progress regarding different types of ethanol organosolv pretreatment processes has been summarized in terms of methods, substrate properties, reaction mechanisms, delignification kinetic as well as the impact of pretreatment methods on the enzymatic digestibility. Attempts are also made to provide insights into the complete utilization of lignocellulosic biomass to achieve high potential revenues. Though some ethanol organosolv processes have been studied or are being developed towards commercialization, ethanol organosolv pretreatment is still facing some challenges. Finally, the direction for future work is given to develop a proper ethanol organosolv pretreatment for commercialization.

>> In recent years, compression ignition engine has been equipped with some control devices such as common rail injection system and turbocharger. In order to control the large number of input parameter appropriately in consideration of NOx, HC and engine power as the engine output objectives. The model construction which reproduces the characteristic value of NOx, HC and engine power from input parameter is needed. In this research, the stepwise method was applied to construct the compression ignition engine model. By using the preliminary experimental data of single cylinder compression ignition engine, the prediction model of NOx, HC and engine power on single injection compression ignition engine was built and compared with the main experimental data.
