Abstract
The purpose of this paper is to improve the energy density and quality of low-grade biomass by appropriate pretreatment, and to study the improvement of transportation efficiency and power generation efficiency. To solve the problem of clinker formation due to ash, we focus on the hydrothermal method as a technology for extracting ash from raw materials. In addition, through a Literature review, the pretreatment technologies that can be applied have been systematically organized, and proposals for effective utilization measures of low-grade biomass have been made. In order to understand the characteristics of agricultural biomass, the characteristics of rice husk and rice straw were analyzed by literature review and TG-DTA analysis. An experiment on hydrothermal treatment was conducted to reduce the ash content of agricultural biomass. In addition, the applicability of pretreatment technology for agricultural biomass in Southeast Asia and China has been evaluated.
