麦草有机酸生物炼制的研究(I)--常压下复合有机酸与麦草的反应特性
Wheat Straw Biorefinery by Organic Acids (I)--Reaction Characteristics of Complex Organic Acids and Wheat Straw at Atmospheric Pressure
摘要
Abstract
Biorefinery process by organic acids is a potential way to utilize wheat straw effectively. The influences of reaction temperature and time on the dissolutions of the wheat straw chemical components in formic acid-acetic acid-water organic acids ( FAWOA) at atmospheric pressure were investigated in present study. The results indicated that the delignification process can be divided into three phases, namely a bulk phase, a complementary one and a residual one, with lignin removal by 37. 1%, 27.2% and 2. 50% respectively. The dissolution of pentosan also demonstrated as three stages, i. e. , a bulk one, a complementary one and a residual one, with the dissolution ratios of 50. 0%, 24. 9% and 3. 20% respectively. The removal of holocellulose, benzene-ethanol and ash can be divided into similar three phases as the removal of lignin and pentosan. The increasing trend of organic matter content in black liquor was similar to that of lignin and pentosan. However, only a slight variation of inorganic matter content was observed and represented a constant level at 2. 0 g/L in the biorefinery process.关键词
