Development of carbonizing gasifier with biomass and waste gasification test results for food-processing waste and oil-plant dregs

Abstract

The biomass and waste are one of the renewable energy that expected to reduce the greenhouse gas emission into atmosphere, and the development of those utilization technologies is a pressing necessity. However, the biomass and waste resources are distributed wide and thinly, and the cost of collection and transportation is expensive. Then, CRIEPI has advanced the development of biomass/waste carbonizing gasification process for small-scale and high-effective power generation system. This process feature is to adopt the carbonizer as pretreatment equipment of the gasifier. A carbonizer makes it possible to use various biomasses and wastes with different chemical property as a fuel of the gasifier. In this paper, the carbonizing gasification test results of the oil-plant dregs (PKS; Palm Kernel Shell and JSD; Jatropha Seeds Dregs) and food processing waste (coffee dregs and beer dregs) are reported.
