The gasification technology has been object of study of many researchers, especially those involved in promoting large-scale electricity generation in sugarcane mills. This paper presents a simplified model for the gasification process based on chemical equilibrium considerations. The model...

Bioethanol converted from lignocellulosic feedstock, such as agricultural waste, is considered one of the most promising biofuels being developed. The raw materials usually need to be pretreated and hydrolyzed by cellulolytic enzymes to produce sugars for subsequent ethanol fermentation....

The mitigation of greenhouse gas (GHG) emissions from power generation and two ethanol production options from sugarcane bagasse were compared at grid emission factors ranging from 0.0 to 1.0kg of carbon dioxide (CO2) equivalent per kWh. The first ethanol production method (EP 1) directly...

Production of bioethanol from lignocellulosic biomass is very challenging due to the heterogenous nature of the feedstock. An efficient pretreatment is necessary for maximizing the enzymatic hydrolysis efficiency and this in turn helps in reducing the total process economy. Conventional...

Microwave alkali pretreated sugarcane bagasse was used as a substrate for production of cellulolytic enzymes, needed for biomass hydrolysis. The pretreated sugarcane bagasse was enzymatic hydrolyzed by crude unprocessed enzymes cellulase (Filter paper activity 9.4 FPU/g), endoglucanase...

In this study, new catalysts were prepared from oil palm trunk (OPT) and sugarcane bagasse (SCB), which are available in enormous quantities. Effect of carbonization time with statistical validation, effect of reaction variables such as catalyst loading, methanol molar ratio, reaction time,...

This paper refers to the new proposal of pre-treatment of sugarcane bagasse with microwave associated to glycerol, seeking greater release of fermentable sugars during enzymatic hydrolysis. The residue was subjected to microwave irradiation for 5min with distilled water, phosphoric acid (pH 3.0)...

The production of ethanol from sugarcane bagasse by simultaneous saccharification and fermentation (SSF) using thermotolerant Kluveromyces marxianus var. marxianus and commercial cellulase of Accellerase 1000 was investigated. Sugarcane bagasse pretreated with NaOH at the room temperature for...

Lignocellulosic materials are rich in cellulose, which can be hydrolyzed into glucose. However, this polysaccharide is associated with lignin and hemicellulose, materials that limit its conversion. The objective of this work was to selectively remove lignin from sugarcane bagasse with sodium...
