摘　　要：阐述了利用串行流化床制取生物质合成气的技术,该技术将生物质气化过程与燃烧过程分开,气化反应器和燃烧反应器之间通过床料进行热量传递,并通过生物质补燃实现自供热。利用ASPEN PLUS软件建立了串行流化床制取合成气的模型,通过将模拟数值与实验结果相比较,验证了模拟研究的可行性。重点研究了气化温度、水蒸汽与生物质的质量配比(S/B)对制取生物质合成气的影响。结果表明,为获取较高品质的生物质合成气并得到较高的碳转化率、气化份额和合成气产率,气化温度以650～800℃为宜,S/B应在0.2～1.0之间。The interconnected fluidized beds technology is described in this paper, which is used to produce biosyngas from biomass gasification. This technology separates the gasification and combustion processes of biomass. The heat is transferred from combustor to gasifier by bed materials ,while extra heat needed in gasification process is provided by additional biomass burning in combustor. ASPEN PLUS software is used to establish the model and simulate the process. The simulated and experimental results are compared to verify the feasibility of the simulation. The effects of gasification temperature and steam to biomass ratio （S/B） on bio-syngas production are studied. The results show that, to achieve higher carbon conversion, gasification proportion and yield of high-quality bio-syngas, the suitable gasification temperature is suitable around 650 -800℃ ,and the S/B is about 0. 2 - 1.0.
