气体调节、净化和模块调整是为各种合成气转化工艺和催化剂制备最佳合成气组成的关键步骤。这些都是Haldor Topsoe A/S自1940年成立以来一直活跃的领域。随着大规模生物质气化，合成气调节和清洁的工业前景，我们提供了一个简短的概述沿着一般考虑。讨论了最近四个大规模的生物质气化炉合成气的调节和净化项目，包括在多尘和清洁环境中焦油的蒸汽重整。在这些项目中，所有关键步骤都与最终产品的合成同时进行了演示，如甲醇，二甲醚，汽油，天然气（甲烷）或适合发电的燃气发动机的合成气。虽然这些解决方案已经商业化，但展望未来，我们预计将开发再生吸附剂热气脱硫技术，用于生物质气化气体中的低硫含量，以显着提高合成气转化为化学品和燃料之前气体调节和净化部分的整体能源效率。
The gas conditioning, purification, and module adjustment are crucial steps in the preparation of an optimal synthesis gas composition for a wide range of syngas conversion processes and catalysts. These are all areas where Haldor Topsoe A/S has been active since the establishment of the company in 1940. With an industrial perspective on large-scale biomass gasification, syngas conditioning and clean-up, we provide a brief overview along with general considerations. Four recent large-scale projects with conditioning and purification of raw biomass gasifier syngas are discussed, with examples including the steam reforming of tar in dusty and clean environments. All crucial steps have been demonstrated in these projects simultaneously with the synthesis of end-products such as methanol, dimethyl ether, gasoline, natural gas (methane), or simply syngas suitable for electricity-generating gas engines. Although the solutions are available commercially, looking to the future we anticipate the development of regenerative sorbent hot gas sulfur removal technologies for the low sulfur contents in biomass gasification gases to significantly further the overall energy efficiency in the gas conditioning and purification sections before syngas conversion to chemicals and fuels.
