Low Quality Organic Carbon Recourse and Its Utilization Techniques

Abstract

Low quality carbon resource is hydrocarbons containing moisture and ashes at high density, which is disposed as waste. Those materials have not been considered as the energy resources for a long time, because of low heating value and difficulty in use. However, it is very important to use those hydrocarbons as the alternative fossil fuels in the aspect of environment and energy security in Japan. There are so many problems and issues in utilization of low quality carbon materials. Therefore, this article explains the present situation and current challenges in the utilization of low quality carbon fuels and introduces new energy utilization techniques of those materials, especially in sludge treatment and utilization.
