Abstract

Abstract: Co-pyrolysis characteristics of pine sawdust and Wucaiwan coal were studied with thermogravimetric analyzer and fixed bed. The effects of catalyst on co-pyrolysis of biomass and coal and the pore structure characteristics of co-pyrolysis char were investigated. The results showed that the pyrolysis characteristics of individual biomass and coal during co-pyrolysis were maintained and there was no synergetic effect in the co-pyrolysis due to different pyrolysis temperature region of the individual biomass and coal. Experimental yields of co-pyrolysis char was higher than the calculated values. The difference between the experimental char yield and the calculated value increased from 0.81 percentage points to 1.07 percentage points with reducing the biomass mass ratio from 75% to 25%. The addition of olivine and olivine supported nickel catalyst(NiO/olivine) promoted the co-pyrolysis reaction. Under the condition of NiO/olivine catalyst addition(the mass ratio of raw material and catalyst 1:1), the co-pyrolysis carbon conversion rate increased by 0.5% to 5.1%. The catalytic activity increased with the increase of biomass ratio in the blend.

Key words: co-pyrolysis of biomass and coal, olivine, char, catalyst, synergetic effect
