褐煤水热改质及改质废水催化气化的研究
HYDROTHERMAL UPGRADING OF LIGNITE AND RECLAMATION OF ITS WASTEWATER BY CATALYTIC GASIFICATION
摘要
Abstract
The autoclave and pressurized fixed bed reactor were used, and the proximate and ultimate analysis of raw and hydrothermal pretreated lignite, the carbon conversion and gas product component were analyzed. By these methods, the hydrothermal upgrading of Inner Mon-gocla lignite and the catalytic gasification behaviors of its wastewater at different temperatures were studied. The results showed that- the hydrothermal process can remove moisture,reduce the oxygen content but increase the fixed and elemental carbon content: the gasification reactivity of the organic matter in the hydrothermal wastewater was higher, resulting in its higher catalytic gasification rate and carbon conversion: the organic matter can be converted into recyclable gas, and the main component of the gas were H2, CO2 and CH4, while the CO content was lower.关键词
