摘　　要：氢能的高速发展对大规模制氢方式提出了新的要求,生物柴油副产物甘油成为较有前景的制氢原料。基于流体动力学和反应动力学,对流化床生物质甘油化学链重整制氢系统进行模拟研究,分析了反应器内的颗粒和组分分布,考察了操作参数对反应产物的影响。研究结果表明:床层内颗粒呈现明显的稀相区和密相区。反应器底部甘油和水被迅速消耗。温度是影响吸附的重要参数,随着温度升高,氢气产量大幅度增加。氧化钙甘油摩尔比的升高明显降低了二氧化碳的含量,但对氢气产量影响不是很明显。入口物料水碳摩尔比的升高在一定程度上提高了氢气的产量。The rapid development of hydrogen energy puts forward new requirements for large-scale hydrogen production.Glycerol as a by-product of biodiesel has become a promising raw material for hydrogen production.Based on hydrodynamics and reaction kinetics,the hydrogen production system of bioglycerol chemical looping reforming in fluidized bed is simulated.The particle and component distribution in the reactor are analyzed,and the effects of operation parameters on the reaction products are investigated.The results show that the particles in the bed show obvious dilute region and dense region.Glycerol and water are rapidly consumed at the bottom of the reactor.The temperature is an important parameter affecting adsorption.With the increase of temperature,the hydrogen production increases greatly.The increase of the molar ratio of CaO to glycerol significantly reduced the content of carbon dioxide,but the effect on hydrogen production is not obvious.The increase of the molar ratio of water to carbon in the inlet increases the hydrogen production to a certain extent.
