摘要

使用1-丁基-3-甲基咪唑氯化盐([Bmim]Cl)、1-丁基-3-甲基咪唑四氟硼酸盐([Bmim]BF4)和1-丁基-1-甲基吡咯烷氯化物([Bmpy]Cl)与水并添加固体酸催化剂Nafion®NR50组成的混合溶剂对孟宗竹进行预处理比较研究

分析了处理后孟宗竹的成分含有量、结晶结构和表面形貌等变化。把处理后的孟宗竹应用于热解研究中

通过TG-DTA和GC-TCD的分析

发现[Bmim]Cl离子液体的混合溶剂处理后的孟宗竹更易于热解反应;此外热解产物更多地从焦炭转化成气体产物;其中添加固体酸的混合溶剂预处理后的1.0 g孟宗竹样品中

在热解反应后焦炭含量为0.19 g

低于未处理样品的0.24 g;生成约0.12 g气体产物大于未处理样品的0.04 g。并探讨了离子液体混合溶剂作为一种新型前处理溶剂应用于生物质热解研究中的潜力和问题。

Abstract

The pyrolysis study of the ionic liquid (IL)-H2O mixtures pretreated bamboo (Phyllostachys edulis) was investigated. 1-Butyl-3-methylimidazolium chloride ([Bmim]Cl)-H2O

1-butyl-3-methylimidazolium tetrafluoroborate ([Bmim]BF4)-H2O and 1-butyl-3-methyl pyrrolidinium chloride ([Bmpy]Cl)-H2O with or without solid acid catalyst (Nafion®NR50) were used in the pretreatment process. The composition analysis result of untreated bamboo and pretreated bamboo were compared. XRD and SEM result were analyzed to explain the effect of ILs mixture on cellulose crystalline structures and surface structures. According to the result of TG-DTA and GC-TCD

the sample pretreated with [Bmim]Cl-H2O mixture was used in the pyrolysis process to produce more gaseous products and low char. About 0.12 g gaseous products and 0.19 g char were produced from 1.0 g sample pretreated with [Bmim]Cl-H2O mixture and added solid acid catalyst

different from the result of untreated sample

0.04 g gaseous products and 0.24 g char. The potential and problems of IL-H2O mixture pretreatment used in thermal chemical conversion methods were discussed.
