Study on seslective synthesis of alternative chemical materials originated from biomass by using non-equilibrium plasma

通过加热固体生物质如木材和废弃物，液体燃料和化学材料，可以获得化石燃料的替代品，因为它通过热解反应产生液体焦油。然而，迄今为止，仅通过给予热量来控制液体焦油的组成是困难的。在本研究中，气体被电解分解为具有高能量的电子和离子（称为非平衡等离子体）。本研究以木材的主要成分之一纤维素为生物质原料，探讨非平衡等离子体处理对木材生物质的影响。研究了氩气和氢气等离子体对焦油气体和液体组成的影响。氩气等离子体促进了纤维素在低温区的热解。

By heating solid biomass such as wood and waste, liquid fuel and chemical materials, alternative of the fossil fuel, can be obtained because it generates liquid tar via pyrolysis reaction. However, it is difficult to control the composition of liquid tar by giving only heat so far. In this study, gas is dissociated electrolytically to the electrons which has high energy and ions (called non-equilibrium plasma) by adding the energy. The objective of the study is to confirm whether non-equilibrium plasma can change the product yield and composition or not.Cellulose, one of major components of wood, was used as a biomass material. The change in gas and liquid tar composition was researched by applying argon or hydrogen plasma. The promotion of cellulose pyrolysis in lower temperature region was suggested with argon plasma.
