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.

There are other factors to influence the occurrence of trace elements. The higher gasification temperature, the higher the relative enrichments of As, Cd, Co, Cr, Cu, Mg, Ni, Pb, Se and the lower of Zn in the high temperature coke and the low temperature coke. The RRE of Mn, Hg, V, Sr are not affected by gasification temperature in the high temperature coke and the low temperature coke.

The usual plan is to put in the water first, then add the indigo and copperas, which should be dissolved first, and finally to add the milk of lime, stirring all the time. Artificial indigo has been made from coal-tar products. The raw material is a coal-tar naphtha called toluene or toluol, which is also the raw material for saccharin, a sweetening agent made from coal-tar.

通常先加水，然后添加靛蓝和已溶于水的绿矾，最后加石灰乳，不时的搅拌人造靛青是取自煤焦油的产品物，原料是所谓甲苯的煤石脑油，这也是糖精的原料，糖精是取自煤石脑油的一种甜剂。

The results showed that 1 the tar delivery was reduced on an average of 0.1mg per cigarette when the density of tobacco rod was decreased by 1mg/cm3, 2 the tar delivery was reduced on an average of 0.3mg per cigarette when the ratio of draw resistance of filter tip to that of whole cigarette was increased by 1%, and 3 the tar delivery was reduced on an average of 1.1mg per cigarette by use of the both techniques.

结果表明：烟支密度每降低1mg/cm3，卷烟焦油量平均可降低约0.1mg/支；滤嘴吸阻占卷烟吸阻的比例每提高1%，焦油量平均降低0.3mg/支左右。综合运用上述2种稳定和降低卷烟焦油量的措施，使"群英会"牌系列产品的焦油量平均值下降了1.1mg/支，焦油量稳定在设计值±1mg/支以内。

The results indicate that tar is highly aromatized at the highest final temperature,the atomic ratio of C/H for PE and waste tire tar is between 0.42 and 0.82,and the high valuable compounds are identified in tar.

研究表明：在试验温度范围内，热解终温对试验物料的焦油产量和焦油族分有明显影响；PE塑料和废轮胎焦油的C／H原子比为0.42～0.82，具有较好的加工性能；PE塑料焦油含有高经济价值的化合物，是很好的化工原料。

Take example for tar as solvent, there are many coking plants with large scale in local region which can supply plenty of coal tar and anthracene oil. It is very convenient to us for cheaper tar and anthracene oil that there are 2 relative large coking plants near our factory with the capacity of 2000-2600 Yuan/t, which save transport costs for us.

如以焦油为溶剂，当地建有多个大型焦化厂，可从焦化厂获得充足的煤焦油和蒽油，非常方便的是在我厂厂址附近甚至是邻居就有2个较大的焦化厂，都可专为我们生产焦油和蒽油，而且价格；较便宜，在2000～2600元/吨之间，还不存在运输费用。

In order to solve the problem of tar in pyrolysis process of coal to produce high quality fuel gas, a novel method of using CaO as catalyst in freeboard of fluidized bed to mildly convert the tar into gas has been proposed and the influence of CaO on tar cracking in the freeboard of fluidized bed at different temperatures is investigated.
