Study on the Effect of n-Hexane Insolubles on Pyrolysis Product Yields Based on Statistical Regression Analysis

Pyrolysis technology has attracted much attention due to its efficient biomass conversion capability, but the significant impact of n-hexane insoluble matter (INS) concentration on pyrolysis product yield has not been fully studied. Therefore, it is of great significance to explore the impact of INS on the yields of tar, water and coke residue. This study developed a linear regression model to analyze the effect of INS concentration on these pyrolysis products. The results show that INS concentration has a significant positive impact on tar yield, but has a smaller impact on water and coke residue yields. In addition, this study constructed a generalized linear model (GLM) to examine the interaction between INS concentration and mixing ratio, and found that the interaction effect was not significant. These findings provide valuable insights into optimizing the co-pyrolysis process of biomass and coal, helping to improve energy conversion efficiency and reduce environmental impact.
