The Interaction Mechanism of Biomass and Coal Co-Gasification

Abstract:

The development of biomass and coal co-gasification technology not only helps to alleviate the energyshortage crisis, but also reduces the pollution of fossil fuels to ecological environment. Co-gasification of biomass and coal can overcome in a certain extent tar emerge in biomass gasification, alkali chloride corrosion, low reaction temperature etc, can increase the calorific value of the gasified gas, can also improve the gasification characteristics. However, due to the biomass compositions differences and the gasification technologies differences, there are the different studies results of co-gasification of biomass and coal. This paper summarized and analyzed the biomass and coal co-gasification study literatures, it is conclude that the biomass compositions can enhance the coal gasification reaction if the biomass compositions intensive mixed with the coal compositions. If not, the biomass gasification and the coal gasification would react separately. This conclusion provides a theoretical basis of the biomass and coal co-gasification and accelerates the biomass gasification technologies development.
