Effect of CH3COOK on the Phenols Production Characteristics of Tobacco Pyrolysis
摘要
Abstract
In order to investigate the effect of CH3 COOK on the phenols production characteristics of waste tobacco pyrolysis and its influencing factors,the effect of different potassium salts on the generation of typical phenolic compounds from the pyrolysis of waste tobacco was investigated.The effect of CH3 COOK on the phenols production characteristics of biomasses pyrolysis with different protein,cellulose,and lignin contents was also analyzed.The results showed that at a loading amount of 5.00％,compared to the unloaded spent secondary tobacco,CH3COOK could significantly reduce the phenol and catechol percentage and enhance the hydroquinone percentage in the tobacco pyrolysis products.Among them,phenol decreased by 45.63％,catechol decreased by 67.88％,and hydroquinone increased by 32.80％.CH3COOK could decrease the proportion of phenol and catechol in the pyrolysis products of tobacco,mulberry leaf and ginkgo biloba with high protein content,and increase the percentage of phenol,catechol,and guaiacol produced by the pyrolysis of pine chips with low protein and high cellulosic lignin.The significant percentage of phenol,p-cresol,and catechol in the pyrolysis products of tobacco proteins was 19.99％,3.08％,and 2.69％,respectively.After loading CH3COOK,the proportions of phenol andp-cresol in pyrolysis products were reduced by 77.09％and 79.37％,respectively,and no catechol was detected.CH3COOK mainly reduced the percentage of corresponding phenols in tobacco pyrolysis products by inhibiting the pyrolysis of proteins to produce phenol and catechol in tobacco.关键词
