Abstract:

Harmless and resourceful utilization of black liquor plays an important role in reducing environmental pollution and alleviating energy shortages. Supercritical water gasification technology is a new and efficient technology for the harmless resource utilization of organic wastewater. It has unique advantages in the harmless and resourceful treatment of papermaking black liquor by utilizing the special properties of water in the supercritical state. The progress of hydrogen production and high value-added chemicals recovery by supercritical water gasification of black liquor in recent years is reviewed. The hydrogen production mechanism is presented and the effects of temperature, pressure, concentration, residence time, and catalyst on hydrogen production by black liquor supercritical water gasification are systematically summarized. The reaction, the separation and recovery mechanism of high economic value salts of black liquor in supercritical water and the development status of supercritical water gasification reaction units for black liquor are introduced. Finally, the prospect of supercritical water gasification of black liquor for hydrogen production and resourceful, harmless treatment to recover useful components is presented.

Key words: black liquor, supercritical water, gasification, hydrogen production, salt recovery, reactor

摘要:

造纸黑液的无害化资源化利用对造纸工业减少环境污染、缓解能源短缺具有重要意义。超临界水气化技术是一种新型且高效的有机废水无害化资源化利用技术,利用水在超临界状态下的特殊性质使其在无害化资源化处理造纸黑液时具有独特的优势。回顾了近年来造纸黑液超临界水气化制氢与高附加值化学品回收的进展,介绍了制氢反应机理,系统总结了温度、压力、浓度、停留时间和催化剂等因素对黑液超临界水气化制氢的影响,介绍了造纸黑液里各类有用无机盐在超临界水条件下的反应、分离回收及造纸黑液超临界水气化反应装置的发展现状。针对现存问题对造纸黑液超临界水气化制氢和资源化无害化处理回收有用成分进行了展望。
