7TH EUROPEAN COKE AND IRONMAKING CONGRESS - ECIC 2016

Biomass is a kind of renewable, clean resource and reducing agent, and has become the focus. In recent years, several papers deal with the combustion and gasification of the biomass, however, the research of biomass ash catalytic reaction process is not elaborated completely. Biomass ash itself usually contains a certain amount of K, Na and other mineral elements, these elements will have a catalytic on gasification process of pulverized coal. In this paper, ash content and ash melting point catalytic to pulverized coal gasification are researched by tube furnace, thermo-gravimetric balance. It is found that there is an obvious catalytic effect of K, Na on the gasification reaction. And the activation energy of the gasification reaction decreased gradually with the increasing of K, Na content.
