The conversion rate of pentavalent vanadium in the calcination process of stone coal with biomass and additives was investigated to determine favourable parameters using Hubei carbonaceous stone coal with low vanadium concentration as raw material.It is found that the addition of biomass enhances the decarburization and roasting processes of the stone coal and the optimal reaction efficiency can be obtained by calcination at 850℃ with ratio of stone coal to biomass 7:3. Adding 4% composite additives(w(Na2CO3):w(CaCO3)=6:4) and roasting at 950℃ for 2 h,the conversion rate of vanadium in the clinker reaches the highest value with 60% of conversion rate for pentavalent vanadium.
