摘      要：An experimental study on co-pyrolysis of bituminous coal and biomass was performed in a pressured fluidized bed *** blend ratio of biomass in the mixture was varied between 0 and 100 wt%,and the temperature was over a range of 550–650℃ under 1.0 MPa pressure with different *** the basis of the individual pyrolysis behavior of bituminous coal and biomass,the influences of the biomass blending ratio,temperature,pressure and atmosphere on the product distribution were *** results indicated that there existed a synergetic effect in the co-pyrolysis of bituminous coal and biomass in this pressured fluidized bed reactor,especially when the condition of bituminous coal and biomass blend ratio of 70:30(w/w),600℃,and 0.3 MPa was *** addition of biomass influenced the tar and char yields and gas and tar composition during *** tar yields were higher than the calculated values from individual pyrolysis of each fuel,and consequently the char yields were *** experimental results showed that the composition of the gaseous products was not in accordance with those of their individual *** improvement of composition in tar also indicated synergistic effect in the co-pyrolysis.
