During the gasification of biomass, tars are produced along with the gases. These compounds can cause operational problems when condensed, decreasing the overall efficiency of the process. Many methods have been explored for the abatement or removal of these compounds, with the most commonly reported being modifications of the gasifier, wet and dry cleaning methods, and thermal or catalytic cracking. Through the cracking of these molecules, more gases are produced, but only a few studies are interested in the char or carbon deposits formed, which, in some cases, can result in carbon nanostructures. For techno-economic and environmental balance of the process, these new carbon structures can bring new possibilities for gasification technologies. Some of the aspects regarding the formation of carbon nanostructures from these kinds of compounds are reviewed in this paper.

生物质气化焦油化合物形成碳纳米结构的展望─小评
在生物质气化过程中,焦油与气体一起产生。这些化合物在冷凝时会导致操作问题,从而降低工艺的整体效率。已经探索了许多方法来减少或去除这些化合物,最常见的报道是气化器的改进、湿法和干法清洁方法以及热裂解或催化裂解。通过这些分子的裂解,会产生更多的气体,但只有少数研究对所形成的炭或碳沉积物感兴趣,在某些情况下,这会产生碳纳米结构。对于工艺的技术经济和环境平衡,这些新的碳结构可以为气化技术带来新的可能性。
