| description | Co-process of biomass and coal is perceived as a way to enhance the energy
utilization by virtue of the integrated and interactive effects between
different types of carbonaceous fuels. The purpose of this study was to
investigate the co-pyrolysis characteristics of Yining coal and poplar
sawdust, and to determine whether there is any synergistic effect in
pyrolytic product yields. The coal was blended with sawdust at a mass
fraction of 9:1, 7:3, 5:5, 3:7 and 1:9 respectively. The change of char
yields, maximum weight loss rate and the corresponding temperature of
different coal/sawdust blends during pyrolysis were compared by
thermogravimetric analysis (TG). The total tar yields during separate coal,
sawdust as well as their blends pyrolysis were acquired from the low
temperature aluminum retort distillation test. By compare the experimental
and theoretical value of the char yields from TG and tar yields from
carbonization test, it was observed that co-pyrolysis of coal/sawdust blends
produced less char and tar than the total amount produced by separate coal
and sawdust pyrolysis. The different product distribution suggested that
there was synergy effect in gas product yields. The co-pyrolysis of
demineralized and devolatilized sawdust with coal indicated that the ash in
the sawdust was the main contributor to the synergistic effect. |
