Abstract

An external thermal high-temperature continuous feed moving bed tubular reactor was used for the gasification of high moisture content lignite (30.41 wt.%) under CO 2 and an auto-generated steam atmosphere. The objectives of this study are to illustrate the synergistic gasification characteristics of high moisture content lignite and CO 2 in the tubular reactor; CO 2 and auto-generated steam (steam released from the lignite) were used as gasification agents for lignite gasification. The effects of temperature and CO 2 flow rate were also investigated. Experimental results showed that when the gasification temperature increased from 800 °C to 1000 °C, the H 2 yield also increased from 8.45 mol kg −1 to 17.86 mol kg −1 . This may indicate that the H 2 O-CO 2 gasification of semi-coke was enhanced with the rise in temperature. At 900 °C, the gas yield increased with the increase in CO 2 flow rate, while the yield of char and liquid product showed an opposite trend. The lower heating value of the H 2 -rich syngas varied from 11.73 MJ m −3 to 12.77 MJ Nm −3 . The experimental results proved that the high moisture content lignite in-situ CO 2 gasification process is an effective methodology for the clean and efficient utilization of lignite.
