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，到目前为止，仅通过加热来控制液态焦油的成分是很困难的。在本研究中，通过添加能量将气体电解解离为具有高能量的电子和离子（称为非平衡等离子体）。研究的目的是确定非平衡等离子体是否会改变产品的收率和组成。纤维素是木材的主要成分之一，被用作生物质材料。研究了氩气等离子体和氢气等离子体对气、液焦油组成的影响。提出了用氩等离子体促进纤维素低温区热解的方法。

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.
