However, higher viscosity, higher moisture, higher acidity, lower heating value and heat instability are unbeneficial properties of bio-oil to be used as liquid fuel. 但是,生物油的高粘度、高含水量、强酸性、低热值和热不稳定等性质严重影响了生物油的品质,阻碍了生物油作为燃料的应用。
Increasing the oxygen content in the gasification reagent, can shorten the gasification reaction time, promote the carbon conversion rate and increase gas yield, whereas, the lower heating value of the produced gas decreased obviously. 气化剂中氧含量的增加,可缩短气化反应时间,促进碳的转化,提高产气率,但可燃气热值却有较大幅度的降低。
Therefore, this paper established the SVM model which adapts to the biomass ( bamboo ) gasification progress so as to predict gas component of biomass, Lower Heating Value(LHV) ( heat value ), gas yield and other indicators of biomass gasification. 为此本文建立了生物质(竹子)气化过程的支持向量机模型用于预测生物质气化气组分、气体热值及气体产率等气化指标。
The oxygen content in biomass and fabric is very high, in the pyrolysis process an exothermic reaction will occur, resulting in a lower total heating value after pyrolysis. 生物质和织物含氧量高、在热解过程中发生了部分燃烧放热反应,热解后的总热值是减少的。
And the relation of the product yield, acid value and heating value was found. The higher the product yield is, the lower the acid value will be, and the higher the heating value will be. 同时还得出生物柴油产率、酸值和热值之间的关系,即产率越高,产物酸值越低,产物热值越高。
