“…Long-term fossil fuel availability issues also become a big concern; therefore, studies on alternative fuels derived from biomass, called bio-fuels, have gained much attention [4][5][6][7][8]. Depending on the type of the process, feedstock and stage of development, the production of biofuel can be classified into primary (first generation) and secondary (second and third generation) [9].…”

Subcritical water hydrolysis of durian seeds waste for bioethanol production

et al. 2015

The feasibility of bioethanol production using durian seed waste was investigated in this study. The effects of hydrolysis parameters (temperature, time, pressure and solid to water ratio) on the yields of reducing sugars and bioethanol were also examined. Central composite design was used to determine the optimum conditions of both reducing sugars yields obtained from hydrolysis stage and ethanol from reducing sugars fermentation. The optimized values for subcritical water process of durian seeds to produce reducing sugars were achieved at temperature of 139.8°C; solid to water ratio of 1:30; pressure of 30 bar; and reaction time of 3.58 h with 32.37 % yield of reducing sugars. The fermentation of 20 g L -1 reducing sugars for 72 h gave the highest ethanol concentration, i.e., 9.85 g L -1 .

“…It is the fourth biggest source of energy in the world after coal, petroleum and natural gas. Biomass is a complex mixture of organic materials, however, the most important components of plant biomass are polymeric carbohydrates (approximately 75%, dry weight) including celluloses and hemicelluloses with lignins which main purpose is strength to the plant structure and holding the fibers together [53]. Cellulose, hemicellulose and lignin build up about 90% of the whole composition of lignocelluloses [47].…”

Abstract:Wheat straw is a sufficient agricultural by-product with a low market price. The biofuel produced from lignocellulosic material exhibits energetic, economic and environmental benefits in contrast to bio-ethanol from starch or sugar. Until now, physical and chemical difficulty caused by the close connection of the main components of lignocellulosic biomass, discourage the hydrolysis of cellulose and hemicellulose to fermentable sugars. The main purpose of pretreatment is to enhance the enzyme accessibility improving digestibility of cellulose. Every pretreatment has a particular effect on the fraction of cellulose, hemicellulose and lignin, thus different pretreatment methods and conditions should be selected for the development of subsequent hydrolysis and fermentation steps. This paper reviews the most importance technologies for ethanol production from lignocellulose and its represent several vital qualities that should be marked for low-price and promote pretreatment processes.

“…[1,2] Plant biomass is the most abundant and available source of biorenewable carbon on our planet, and is viewed as the main sustainable alternative to petrochemical derived chemicals and fuels. [1,3,4] Lignocellulosic plant material in particular has been specifically earmarked for conversion to higher value chemicals and fuels. The vast natural abundance of lignocellulosic material and potential for further functionalisation to generate industrially important chemicals could make them viable alternatives to crude oil derived products.…”

Homogeneous Catalyzed Reactions of Levulinic Acid: To γ‐Valerolactone and Beyond

et al. 2016

Platform chemicals derived from lignocellulousic plant biomass are viewed as a sustainable replacement for crude oil based feed-stocks. Levulinic acid (LA) is one such biomass derived chemical that has been widely studied for further catalytic transformation to γ-valerolactone (GVL), an important 'green' fuel additive, solvent and fine chemical intermediate. Although the transformation of LA to GVL can be achieved using heterogeneous catalysis, homogeneous catalytic systems that operate under milder reactions, give high seletivities and can be recycled continue to attract much attention. A range of new homogeneous catalysts have now been demonstrated to efficiently convert LA to GVL, and to transform LA directly to other value added chemicals such as 1,4-pentanediol (1,4-PDO) and 2-methyltetrahydrofuran (2-MTHF). This mini review covers recent advances in the area of homogeneous catalysis for the conversion of levulinic acid and levulinic ester derivatives to GVL and chemicals beyond GVL.
