酸性糠醛残渣热解实验及热解炭性能研究
Acidic furfural residue pyrolysis experiments and pyrolytic carbon performance
摘要
Abstract
In order to solve the furfural slag pile and the rational use of resources,with furfural residue as the research object,the pyrolysis experiments were conducted in synchronous thermal analyzer and tubular furnace respectively.The final pyrolysis temperature,heating rate and sodium carbonate that influenced the furfural residue pyrolysis product distribution and the pyrolytic carbon performance were mainly investigated.The synchronous thermal analyzer increased to 850 ℃ (adding sodium carbonate at 10 ℃/min) respectively with the heating rate of 10-40 ℃/min.The tube furnace reached the terminal temperature pyrolysis at 300-600 ℃with the heating rate of 10 ℃/min.The results show that the whole thermal decomposition weightlessness process can be divided into three sections of drying section,the volatile evolution section and pyrolysis coking section,and the main pyrolysis temperature range is 300-600 ℃ by the thermogravimetric analysis.After adding sodium carbonate inhibited the precipitation of moisture,the weightlessness rate peak become larger,which showed that alkali metal sodium salt promoted the decomposition of cellulose.The pH of the pyrolytic carbon gradually increased with the increases of pyrolysis temperature,and reached the highest when the methylene blue decolorization rate was 44.4％ with the pyrolysis temperature of 400 ℃.The pyrolytic carbon should be further used in the activated carbon for dye adsorption.关键词
