The results indicate the mutual effect exists between the single coals, which could increase the maximum of thermal weight loss obviously and has a small effect on the temperature extent of the weight loss. The main pyrolysis production of coal is coke, but the main production of waste plastics is tar; the yield of water became decrease and the gas became increase by adding the waste plastics. And the CRI and CSR decreased with the ratio of waste plastics in coal. The main ingredients of tar from blend coal are aromatic hydrocarbon and alkane, while those of waste plastics are alkane and alkene. The result of co-coking with coal and waste plastics make the light tar and the aromatic hydrocarbon increase obviously. The combustible ingredient(CO、H2、CH4) of gas from co-coking with coal increase at different ratio; Co-coking with coal and waste plastics could increase the combustible ingredient and thermal value of gas.
结果表明,废塑料与煤混合物在煤的塑性温度区间内存在明显的相互作用,使最大热解失重峰迁移,热解速率变大,且随着废塑料配比的增加呈现规律性的变化;煤热解产物固体焦炭为主,而废塑料的热解产物以焦油为主,废塑料的添加使得总体焦炭和水产率下降,焦炉煤气和焦油的产率增加,即共焦化呈现出明显的&增油减水&效应;随着塑料添加量的增加,焦炭热强度呈现劣化趋势;废塑料代替瘦煤配煤炼焦可使其比例提高到3%而不影响焦炭的质量;纯煤焦化所得焦油以芳香烃类和烷烃类为主,而废塑料热解焦油以烷烃和烯烃为主;废塑料配煤炼焦,可使得的焦油呈现&环构化&和&轻质化&趋势;废塑料的添加可使煤气中的可燃组分(CO、H2、CH4)的含量均有不同程度的增加;废塑料配煤炼焦可以优化焦炉煤气的组成,增加煤气中的可燃组分,提高焦炉煤气的热值。

The results show that the torsion energy and van der Waals interaction energy are the main types of energy and the substitution group has a great effect on the total energy of molecular. The aliphatic substitution would lead to the increase of total energy, while the aromatic substitution would lead to the decrease of total energy. The calculated results of bond length show that the bond length of aliphatic C—C is longer than that of aromatic C—C, which indicates that the rupture of aliphatic C—C is easier than that of aromatic C—C on heating.
研究结果表明,扭转能和范德华能是分子中的主要作用力,取代基对体系能量有明显影响,烷基取代基使体系能量增加,而苯基取代基使体系能量降低;脂肪C—C键长比芳香C—C键长长,说明脂肪C—C在受热过程中比芳香C—C更容易断裂分解。
