Isolation of Phenolic Fraction from Liquid Pyrolysis Products of Wood |
|
| چکیده انگلیسی مقاله |
The creation of conditions for the rational and multipurpose use of forests has become an urgent task within the forest industry. There is an active search for opportunities to use bio-oil derived from wood waste obtained through fast ablative pyrolysis. Bio-oil has a rich chemical composition, making it relevant to isolate individual chemical components from it. The main objective of this work was to investigate a method for extracting the phenolic fraction from the pyrolysis fluid of wood waste and to obtain and study samples of side fractions obtained during phenolic extraction. This paper describes a method for the fractionation of wood waste pyrolysis fluid based on a multi-stage complex process, including vacuum distillation, liquid-liquid extraction, and acid-alkali precipitation. A detailed description and scheme of the processes are presented in the paper. The properties and chemical compositions of the obtained fractions were investigated. In the fractionation process, a phenolic fraction containing at least 60.38% of phenolic compounds was isolated. The first stage of the separation produces a fraction with a high content of acetic acid, while the third stage leads to the separation of a fraction containing sugars. Additionally, a fraction containing up to 22% furfural is formed. The fractions obtained at each separation step have both scientific and commercial potential, in addition to the target phenolic fraction. |
