佩鲁贾大学开发了一种综合热解再生工厂，它可以与蒸汽气化工厂集成，从木炭中生产氢气。在蒸汽气化中使用木炭代替生物质的优点表现为焦油产量的减少。为了验证这种新的设备概念，进行了将水进料到热炭床中的实验活动。一个有趣的气体成分进行了测量，与氢气浓度等于58.26%的体积。基于实验室试验的质量和能量平衡，设计了基于热重整阶段的装置，耦合蒸汽气化，重点分析了热重整和蒸汽气化过程之间的热集成。结果表明，热解过程可以完全提供热解本身、重整阶段和水蒸气气化阶段的反应热。可以实现每千克生物质0.03千克氢气的产量。(C)2018爱思唯尔有限公司版权所有
The University of Perugia has developed an Integrated Pyrolysis Regenerated Plant, which can be integrated with a steam gasification plant to produce hydrogen from charcoal. The advantage of using charcoal instead of biomass in steam gasification is represented by the reduction of tar production. To verify this new plant concept an experimental campaign was performed feeding water into a hot char bed. An interesting gas composition was measured, with hydrogen concentration equal to 58.26% in volume. Based on the mass and energy balance of the experimental tests a plant based on a pyro-reforming stage, coupled with a steam gasification was designed, focusing the analysis on heat integration between the pyro-reforming and the steam gasification process. The results show that the pyrolysis process can entirely provide the heat of reaction of the pyrolysis itself, the reforming stage and the steam gasification stage. A yield of 0.03 kg of hydrogen for 1 kg of biomass can be achieved. (C) 2018 Elsevier Ltd. All rights reserved.
