Abstract

In the complete green synthesis technology chain, bio-syngas production remains the “first hurdle”. Especially, the “tar” problem in biomass gasification urgently needs to be solved. Recently, our team, in collaboration with Jinan Huangtai Gas Stove Co., Ltd., completed a 10,000-ton industrial test and technical verification of fluidized bed two-stage O₂/steam gasification for production of syngas from biomass. The test results showed that the fluidized bed two-stage gasification was operated continuously and stably for over 110 h with various biomass feedstocks. Additionally, the lowest tar content in the produced gas reached 0.58 g/Nm³. The fly ash collected from the continuous test contained carbon of about 30 wt%. Thus, the technology was well proved for large-scale biomass gasification and production of syngas in terms of technical feasibility and operational stability.

流化床两级O2/蒸汽气化农业生物质低焦油合成气：工业规模验证试验

在完整的绿色合成技术链中，生物合成气生产仍然是“第一关”。特别是生物质气化中的“焦油”问题亟待解决。最近，我们的团队与济南皇泰燃气炉有限公司合作，完成了流化床两级O2/蒸汽气化生产生物质合成气的万吨级工业试验和技术验证。试验结果表明，流化床两段气化在不同生物质原料下连续稳定运行110 h以上。采出气中最低焦油含量达到0.58 g/Nm3。从连续试验中收集的飞灰含碳量约为30%。因此，该技术在技术可行性和运行稳定性方面已经很好地证明了大规模生物质气化和合成气生产的技术可行性。

期刊介绍： Carbon Resources Conversion (CRC) publishes fundamental studies and industrial developments regarding relevant technologies aiming for the clean, efficient, value-added, and low-carbon utilization of carbon-containing resources as fuel for energy and as feedstock for materials or chemicals from, for example, fossil fuels, biomass, syngas, CO2, hydrocarbons, and organic wastes via physical, thermal, chemical, biological, and other technical methods. CRC also publishes scientific and engineering studies on resource characterization and pretreatment, carbon material innovation and production, clean technologies related to carbon resource conversion and utilization, and various process-supporting technologies, including on-line or off-line measurement and monitoring, modeling, simulations focused on safe and efficient process operation and control, and process and equipment optimization.
