Production of ethanol by bioconversion of lignocellulosic biomass has attracted much
interest in recent years. However, the pretreatment process for increasing the enzymatic …

Fractionation of wheat straw was investigated using an atmospheric acetic acid process.
Under the typical conditions of 90%(v/v) aqueous AcOH, 4% H2SO4 (w/w, on straw), ratio of …

Lignin has been explored extensively as a renewable precursor for carbon materials,
considering its abundance as a major component of plant cell walls and its sustainability as …

Rice straw pulping with formic acid was studied for different temperatures, cooking times and
acid concentrations. Delignification percentage of approximately 85% with a pulp yield of …

A detailed examination was made of the behavior and distribution of ash and silica during
atmospheric acetic acid pulping and subsequent bleaching of rice straw. Ash-rich pulps (in …

The selective separation of cellulose, hemicelluloses and lignin of triticale straw is achieved,
at atmospheric pressure, using a mixture of formic acid/acetic acid/water. The chemical and …

Lignins obtained by atmospheric acetic acid delignification of rice straw, birch and fir were
characterized by molecular weight, solubility and thermomechanical analysis, and by …

Wheat straw, as an agricultural residue, is generated in a huge quantity worldwide every
year. In countries that are short of forest resources, such as China, wheat and rice straws are …

Atmospheric acetic acid pulping of wheat straw was carried out. Pulping conditions and their
effects on pulp properties were investigated in detail, and a comparison between acetic acid …

Acetic acid lignins from rice straw (RLs), birch (BL) and fir (FL) were chemically
characterized by means of elementary analysis, functional groups analysis, alkaline …
