No.1-5 Characteristics of Co-char Produced from Low Rank Biomass and Coal by Co-pyrolysis

Abstract

To utilize low rank biomass energy, we are proposing co-gasification process that coal is mixed. For co-gasification of sludge and coal, it is important to reveal characteristics of co-char produced from sludge and coal by pyrolysis. So, we reported gasification behavior of co-char and difference of reactivity between single chars (sludge char and coal char) and co-char previously. In this study, it was revealed the difference of property between single chars and co-char from points of elemental analysis, SEM image and raman spectrum. And it was considered about interaction of co-pyrolysis when sludge and coal were pyrolized at the same time.
