Homogenous acylation and carbanilation reactions of wood-based lignocellulosic materials have been investigated in ionic liquids. We have found that highly substituted lignocellulosic esters can be obtained under mild conditions (2 h, 70 degrees C) by reacting wood dissolved in ionic liquids with acetyl chloride, benzoyl chloride, and acetic anhydride in the presence of pyridine. In the absence...

Bioethanol is mostly produced from wheat starch in Sweden. Due to the increasing wheat price it is no longer profitable to produce bioethanol from wheat. In this paper the conditions for converting a wheat bioethanol plant to a lignocellulosic bioethanol plant are studied. The most suitable lignocellulosic feedstock is investigated and soft wood chips are chosen based on bioethanol ...

Lignocellulosic biomass is the most abundant renewable raw material on the earth and it is so far the most suitable and promising resource for the production of biofuels to replace long-term use of fossil oil. This research aims to convert lignocellulose-based industrial residuals, fibre sludge (FS) from a pulp mill and pine sawdust (PSD) from a sawmill, into platform sugars by two different bi...

In this paper the kinetics of biogas production was studied by performing a series of laboratory experiments using different lignocellulosic biomass mixed with fresh cattle dung at three different temperatures. Laboratory digesters each of 1000 ml capacity were used for the laboratory experiments in batch mode. Five different types of lignocellulosic biomasses such as bamboo dust, saw dust, sug...

Progressive depletion of oil and conventional fossil fuels, an increased energy demand and an increased struggle for national energy security has led to the development of alternative biobased fuels, bioethanol being one of them. Bioethanol can be made from many different raw materials, and based on this are classified as 1 generation and 2 generation. This research work dealt with 2 generation...

Production of ethanol from lignocellulosic feed-stocks is of growing interest worldwide in recent years. However, we are currently still facing significant technical challenges to make it economically feasible on an industrial scale. Genetically modified lignocellulosic biomass has provided a potential alternative to address such challenges. Some studies have shown that genetically modified lig...
