摘要
利用2kg模拟焦炉系统进行煤、城市生活垃圾单独热解和两者不同配比下共热解实验,对所得焦油成分进行分析,结果表明,神华煤热解焦油成分主要以芳香烃(41.13%)和烷烃(30.79%)为主;生活垃圾热解焦油成分主要以烯烃(25.70%)和烷烃(28.38%)为主。与理论计算数据相比,共热解焦油中苯萘类油含量增加3.20%~7.97%,链烃类(烷烃和烯烃)含量增加10.14%~12.69%,含氧官能团有机物成分减少6.6%~14.64%,共热解焦油成分呈现出明显的"链烃化"趋势。
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 pyrolysis had the obvious "chain hydrocarhylation" tendency.
