Tar evolution profiles obtained from gasification of biomass and coal
TLDR
In this article, evolution profiles of the main tar constituents of the product gases from gasification of biomass are presented. But the authors do not consider the effect of the subsequent process stages on the resulting tar content.Abstract:
The tar content of the product gases from gasification of biomass is one of the major factors affecting the subsequent process stages. In this work, evolution profiles of the main tar constituents, ...read more
