Synergistic Effects of Hydrogen Production from Steam Catalytic Co-Gasification of Waste Tires and Torrefied Elm
摘要
Abstract
To improve the hydrogen yield from waste tire biomass co-gasification and to reveal the synergistic mechanism,gasification and catalytic gasification experiments were conducted using elm,torrefied elm,and waste tires as feedstocks.The effects of torrefaction temperature,waste tire(F)mass fraction,steam,and catalyst on the hydrogen yield(YH)and the synergistic effect were analyzed.The results showed that,the catalyst exhibited little effect during single-component gasification,whereas under steam conditions,torrefied elm at 220 ℃ achieved the highest φ(H2)of 47.50％.During co-gasification without steam,YH values were generally lower than the theoretical ones,indicating a weakened synergistic effect;however,the introduction of steam enhanced the synergy.At 220 ℃ torrefaction,YH increased by 10.4％and 30.0％compared with the theoretical values at ω(F)=35％and 50％,respectively;at 250 ℃,the increments were 17.9％and 30.1％,and at 280 ℃ with ω(F)=20％,the increment reached 32.7％.Under steam conditions,the catalyst enhanced YH,showing a 42.52％increase at 220 ℃ torrefaction with ω(F)=20％compared with the non-catalyzed sample,but no significant improvement in synergy was observed.It is therefore indicated that selecting an appropriate ω(F)(20％-35％)and a torrefaction temperature of 220 ℃ can effectively improve hydrogen yield,although the optimal catalytic gasification conditions for hydrogen production still require further investigation.关键词
