Characteristics of Tar Generation during Devolatization and Gasification of Woodchip

Woodchip, a carbon neutral fuel, is one of the fastest growing renewable energy sources. Among many conversion methods to energy, gasification is the best way in terms of energy efficiency and various options for end use like heat, steam, electronics, gaseous and liquid fuel. In the gasification process of woodchip, tar treatment is very important to avoid any mechanical problems and to increase heating value of product gas. However, tar generation process is not fully understood yet. In this study, we investigated tar generation characteristics of woodchip in devolatization and char gasification process. We found that different kinds of tar was generated in the devolatization and gasification process. The effects of temperature and steam amount are also studied.
