Abstract:

The composition of tar obtained from independent pyrolysis of coal and municipal solid waste and co-pyrolysis of coal and municipal solid waste under different blending ratio by means of 2kg simulating coke oven system was analyzed. The result showed that the composition of tar from pyrolysis of Shenhua coal was mainly contained with aromatic hydrocarbon（41.13%）and alkane（30.79%）；the composition of tar from pyrolysis of municipal solid waste was mainly contained with olefine（25.70%）and alkane（28.38%）. Compared with the data from theoretical calculation, the oil content such as benzene and naphthalene in co-pyrolytic tar was increased by 3.20%~7.97%, the content of chain hydrocarbon（alkane and ole fine） was increased by 10.14%~ 12.69%,  the organic composition of the oxygen-bearing functional group was reduced by 6.6% ~ 14.64%, the composition of tar from pyrolysishad the obvious “chain hydrocarhylation” tendency.
