摘要

摘要在松材中加入相同摩尔量的碱土和碱土金属物质,研究其对生物质热解和二氧化碳辅助气化的影响。首先,通过热重分析研究了碱和碱土金属对松材的热解行为。采用半间歇式固定床平台对气体产品参数进行量化,包括气体质量流量、产气量、回收能量、能源效率和净二氧化碳消耗量。热重分析结果表明,碱和碱土金属在低温下对松材的热分解有促进作用,在高温下对松材的热分解有抑制作用。在热解过程中,添加碱土金属可提高合成气产率、回收能量和能源效率,而添加碱土金属则相反。对于气化,碱金属负载比碱土金属负载的松木表现出更强的催化作用。基于一氧化碳的演化,碱和碱土金属对生物炭气化反应性的增强作用顺序为:钠;钾和gt;钙和gt;镁。此外,碱金属的添加表现出更强的二氧化碳消耗能力,有助于温室气体的管理。仅从能效角度考虑,在生物质热解过程中加入碱土金属是一种最佳选择,因为在更短的时间内获得了更高的整体能效。

Effect of Alkali and Alkaline Earth Metallic Species on Gas Evolution and Energy Efficiency Evolution in Pyrolysis and Co2-Assisted Gasification
Abstract In this study, the same moles of alkali and alkaline earth metallic species were introduced into pine wood to investigate their effects on biomass pyrolysis and carbon dioxide-assisted gasification. First, thermogravimetric analysis was conducted to examine the pyrolytic behavior of pine wood loaded with alkali and alkaline earth metallic species. A semi-batch fixed bed platform was used to quantify gaseous product parameters, including gas mass flow rate, gas yield, recovered energy, energy efficiency, and net carbon dioxide consumption. Thermogravimetric results indicated that the loading of alkali and alkaline earth metallic species promoted the thermal decomposition of pine wood at low temperatures, but an inhibitory effect was observed at high temperatures. In terms of pyrolysis, adding alkaline earth metals increased syngas yields, and recovered energy, as well as energy efficiency, whereas alkali metals had the opposite effect. For the gasification, the loading of alkali metals showed a stronger catalytic than the pine wood loaded with alkaline earth metals. Based on the evolution of carbon monoxide, the effects of alkali and alkaline earth metallic species on enhancing the biochar's gasification reactivity were in the sequence of sodium > potassium > calcium > magnesium. In addition, the addition of alkali metals exhibited a stronger capacity for carbon dioxide consumption, which contributed to the management of the greenhouse gas. Considering only energy efficiency, adding alkaline earth metals in biomass pyrolysis is an optimal choice due to the higher overall energy efficiency obtained in less time.
