Tar oil is the by-product of the production of coke oven and it contains separable products of high additional value. For a coke-making factory, when the production of tar oil reaches certain amount, it is necessary to do tar oil processing, which is an efficient way to get a new economy increasing point.

焦油是焦炉生产的付产品，其中含有可分离的高附加值产品，对于一个焦化厂来说，当焦油的产量达到一定规模时，增设焦油加工是必然的，也是企业增加新的经济增长点一个有效途径。

By using the fact of tar exiscing in surplus ammonia water the SCCP condensation system,the reason of tar existing in surplus ammonia water is analyzed,and the method removing tar is discussed.

对于焦化厂冷凝系统剩余氨水带油的问题，从理论和实践分析了带油原因，并对剩余氨水除油方法进行了探讨。

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。

Tar is undesirable due to condensation, formation of tar aerosols and polymerization to form more complex structures, which cause blockage in transporting pipe and damage to engines and turbines. Then, tar is still the bottleneck of the technology.

生物质气化是一种主要的生物质能利用方式，但是在气化过程中产生的焦油给生物质气化技术应用带来了一些问题。

The results show:the amount of tar is declining when flue-cured which is low tar,combustion-supporting,the use of additives,reconstructed tobacco,expended tobacco while the amount of tar is same when cigarettes paper which is high porosity which are pereated are used. But if the porosity of cigarette paper are too high,the quality of cigarettes inside will be effected.

结果表明：采用焦油含量低的烤烟烟叶、膨胀烟草、烟草薄片、合适的烟用添加剂，则焦油量呈下降趋势；在辅助材料方面，使用高透气度盘纸，则焦油量呈下降趋势，但通气度不易过高，否则影响卷烟的内在质量。

The chemical kinetic modeling of NO reduction by a typical tar model compound is studied, in order to discover the mechanism of NO reduction by tar. Base on the mechanism of NO reduction by hydrocarbon and non-hydrocarbon intermediates produced in the tar oxidative decomposition, the chemical kinetic modeling of NO reduction by toluene is studied.

分析结果表明，苯、甲苯、苯乙烯和苯酚均有明显的累积离子流峰面积，是生物质焦油的主要组分，涵盖了初级、二级和三级焦油产物，所以选取苯、甲苯、苯乙烯和苯酚作为典型的生物质焦油的模型化合物。
