the objective of this work focuses on the use of a new natural lignocellulosic material based on palm stems for adsorbing of hexavalent chromium (cr(vi)) in water. the palm stems powder (psp) was characterized using different techniques. the influencing factors on the adsorption of cr(vi) ions was investigated such as ph. the results show that the increase of the temperature and the initial ads...

The present invention provides wood derivatives and composite materials prepared by first solvating a lignocellulosic material using an ionic liquid. The solvated lignocellulosic material can be derivatized to incorporate functional groups, particularly groups that facilitate later combination with polymer materials, including non-polymer polymers. The polymeric materials can be combined with t...

The present invention provides methods for the thermolysis of lignocellulosic materials, such as wood, cellulose, lignin, and lignocellulose. In specific embodiments, the methods comprise combining the lignocellulosic material with an ionic liquid and subjecting the mixture of the lignocellulosic material and the ionic media to pyrolytic conditions to form a recoverable product, such as a commo...

Lignocellulose is a renewable organic material and major structural component of all plants. Lignocellulose consists of three major components: cellulose, hemicellulose and lignin. In addition, small amounts of other materials such as ash, proteins and pectin found in lignocellulosic residues in different degrees based on the source (Sanchez et al., 2009). Cellulose is major constituent of all ...

Lignocellulosic biomass, which contains cellulose (40-50%), hemicellulose (25-50%) and lignin (10-40%), is the most abundantly available raw material on Earth [1]. Broadly, it is classified into three categories: virgin biomass, waste biomass and energy crops. Owing to the rapid growth of global population and corresponding agricultural activities, the amount of lignocellulosic waste biomass is...

Lignocellulosic biomass is a complex biopolymer that is primary composed of cellulose, hemicellulose, and lignin. The presence of cellulose in biomass is able to depolymerise into nanodimension biomaterial, with exceptional mechanical properties for biocomposites, pharmaceutical carriers, and electronic substrate's application. However, the entangled biomass ultrastructure consists of inherent ...

BACKGROUND The description of new hydrolytic enzymes is an important step in the development of techniques which use lignocellulosic materials as a starting point for fuel production. Sugarcane bagasse, which is subjected to pre-treatment, hydrolysis and fermentation for the production of ethanol in several test refineries, is the most promising source of raw material for the production of seco...
