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。

The study showed that interaction of co-carbonization of coal tar pitch and lean coal was the coaction of physical bond and chemical interaction, in which the bond state of coke interface was improved by physical bond, and coal tar pitch varied the carbonization behavior of lean coal through chemical interaction with the increase of the blending ratio of coal tar pitch, the caking property of coal blend was greatly improved, OTI value of coke was increased, while ISO value was reduced.

其中物理融合表现在使焦炭界面结合状态改善，化学相互作用表现在煤沥青使贫煤的炭化性能发生变化。随煤沥青配比的增加，配煤黏结性有较大改善，焦炭OTI值增大，ISO值减小。

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.

为了解决在煤热解制取高质量燃料气过程中焦油带来的问题，提出了在流化床稀相段空间利用CaO作催化剂将焦油温和地转化为气体的新方法，考察了不同温度下氧化钙对煤热解生成焦油催化裂解行为的影响。

So, a technical routine of biomass gasification gas reburning with tar, or biogas reburning without tar removal, is put forth to deal with the comprehensive utilization of tar in the present work.

虽然学者们对脱除焦油做了大量研究工作，但是目前还缺少高效、经济的脱除焦油的成熟技术，从而限制了生物质气化技术商业化应用。

The principle of electric tar Filter is that, high voltage electric field formed by direct voltage with voltage between 40～60 KV makes the tar in gas fuel to be absorbed and deposited in electro tar precipitator.

电捕焦的原理是利用40～60 KV 的直流电压形成高压电场，通过沉淀极，使气体中的焦油在电捕焦油器内吸附、沉淀，提高焦油过滤效率，降低设备成本。

The coal tar pitch powder was used with each of 22 kinds of dispersants prepared coal tar pitch water slurry,and 6 kinds of dispersants were selected to prepare coal tar pitch water slurry with the high temperature coal tar pitch powder which has a softening point of 105℃.

采用冷冻粉碎的方法将软化点为90℃的中温煤沥青制得粒度≤200目的煤沥青粉后，再与22种分散剂制备煤沥青水浆，从中筛选出6种成浆性好的分散剂再与软化点为105℃的高温煤沥青粉制备煤沥青水浆，结果表明中温煤沥青粉比高温煤沥青粉更易制得稳定性好的煤沥青水浆。

Though many researchers have been working on tar removal, the efficient and cheap removal of tar is still immature and the main technical barrier for the successful commercialization of biomass gasification technology. Some research indicate that oxidation of tar produces light C1-2 hydrocarbons that can reduce NO, which means that tar can reduce NO.

由于焦油凝结、形成烟雾、聚合成更复杂的结构，造成生物质气化气输送管道的堵塞，损害内燃机和燃气轮机，因而焦油成为限制生物质气化技术应用的瓶颈。
