混合醇对生物燃油主要物性的影响
The Effect of Mixed Alcohols on Physical Properties of Bio-oil
摘要
Abstract
In order to improve the physical properties and stability of bio-oil,the mixed alcohol of methanol and ethanol with the mass ratio of 1:1 as additive was added different mass fraction into the bio-oil obtained from fast pyrolysis of agricultural and forestry wastes as the sample. And the effect of different mass fraction of additive on the main physical properties of bio-oil,such as kinematic viscosity, water content, heat value, flash point, density and pH value were studied. The experimental results showed that the mixed alcohol could improve the physical properties of bio-oil. As the additions amount of 5% -40%, the kinematic viscosity of bio-oil increased by 1.289-2.049 mm2/s, the moisture content decreased by 10.07%-44.75%, the calorific value increased by 1.70%-11.14%,the flash point decreased by 1.99%-14.44%,the density decreased by 1.56%-12.23%,the pH value increased by 8.51%-70.21%,and the rate of change reduced,which indicated the physical properties of bio-oil could be improved by adding the mixed alcohol.关键词
