摘要：采用蜂窝陶瓷热交换技术廉价地获得高温介质,在固定床热解反应器中研究了沙柳和柠条在高温介质（蒸汽、氮气）中的热解行为及其对热解固体产物的影响,结果表明：高温蒸汽热解技术有助于热解可以获得挥发分低、比表面积大的高性能固体炭产品,在958 K下热解沙柳固体炭比表面积达280 m2/g.沙柳和柠条在不同高温介质下最大失重可达80％,固体炭得率20％～30％.随着热解介质温度的提高,生物质热失重速率提高,热解时间缩短.在相同的热解温度下,蒸汽介质中生物质热失重率大于N2介质.
The super-high temperature medium with low cost was obtained by the technology of the honeycomb ceramic heat exchanger.The pyrolysis behavior of super-high temperature medium （steam and nitrogen） and their influences on the components of pyrolysis products were investigated in the fixed bed pyrolysis reactor.The research results showed that the technology of super-high temperature steam pyrolysis trends to prepare high value solid carbon materials with low volatile content and large specific surface area by high-temperature steam pyrolysis.The surface area of solid char from willow pyrolysis at 958 K under steam medium is 280 m2/g.The loss of mass ratio under different mediums is about 80 ％ and the yield of solid carbon is 20％-30％ using willow and caragana as raw materials.With the increase of pyrolysis medium temperature,the ratio of mass loss is improved and the time of pyrolysis becomes short.At the same of pyrolysis temperature,the rate of mass loss in the steam medium is greater than that in the N2 medium.
