Effect of coal ash additive on potassium fixation and melting behaviors of the mixture under simulated biomass gasification condition

In order to solve the ash related problems (such as corrosion and agglomeration) caused by potassium(K) species for efficient and clean gasification of biomass. It is feasible to add additives during the biomass gasification procedure. Coal ash has been proven to be an effective adsorbent for the gaseous K. However, the influence of coal ash on K retention in the solid phase is unclear, the interacting mechanisms and ash melting characteristics...
