摘　　要：纤维乙醇生产过程中会产生大量的黑液,为了更好的对纤维乙醇黑液进行处理,利用旋转黏度计对这种黑液进行了流变性测定,并对其流变特性进行了分析.结果表明:纤维乙醇黑液为非牛顿流体中的假塑性流体,其流变特性服从幂律方程,该黑液的温度和固含量对流变特性参数都有一定的影响.所获得的结论对纤维乙醇黑液的研究有着十分重要的工程实际意义.Cellulose fuel ethanol will produce a lot of black liquor during the production of cellulose fuel ethanol.In order to deal with black liquor of cellulose fuel ethanol better,rheology behaviors of this kind of black liquor was tested with rotary viscometer in this paper.The rheological characteristics of this kind of liquor was also analyzed.The conclusion is that black liquor of cellulose fuel ethanol is pseudoplastic Non-Newtonian fluid,its rheological characteristics meet with power-law exquation,and its temperature and solid content have an influence on the rheological properties of parameters.The results of the research on black liquor of cellulose fuel ethanol has a very important practical significance for the project.
