中国科学院山西煤化学研究所，山西太原 030001）摘要：开发了高温煤气净化新工艺，进行了自行研制的脱硫剂在流化床气化条件下的气流床脱硫和流化床再生工艺、脱硫剂的硫化和再生过程动力学行为研究。

In the early 1920s, Franz Fischer and Hans Tropsch patented a process to produce a mixture of alcohols, aldehydes, fatty acids and hydrocarbons known as synthol, from a synthesis gas of hydrogen and carbon monoxide.

乙醛，和碳氢化合物组成的。F-T工艺是间接煤液化的基础。因为通过蒸馏和氧气的气化作用，煤结构被完全分解成合成气，所以此工艺是间接的。然后这些气体通过适当的F-T催化剂的作用，大部分形成蜡油状的碳氢化合物，分子亮分布较宽。wjk678 发布在翻译例文|发布时间： 12：20PM Apr 23， 2008 |评论

Tars from mild gasification of Shenmu coal on fludized bed reactor were analyzed and compared with pyrolysis on FBR.

采用色质联用技术分析了流化床煤温和气化过程产生焦油的组成及其相对含量。

As one of the advanced techniques for energy conversion, the thermochemical gasification of biomass to hydrogen production has the advantages in environment protection and endless raw materials.

作为能源转化的先进技术之一，利用热化学气化方法将生物质能洁净转化为氢能有着巨大的应用技术潜力和市场前景。

The experimental results show that the distributions of content and toxicity equivalent quantity of PAHs in raw coal are similar to coal gasification but this compositions and contents are different. The rise of coal rank leads to the decrease of the content and TEQ of PAHs in raw coal and the increase of TEQ during coal gasification, while the content of PAHs emission from coal gasification increases first and then decreases with the increase of coal rank. The total PAHs contents generated in coal gasification of some sorts of coals are higher than in raw coal. The types of PAHs formed in coal gasification include undecomposed PAHs in raw coal, pyrosysthensis PAHs, and radical polymerization PAHs at high temperature.

试验结果表明：煤气化前后多环芳烃质量分数和毒性当量质量分数的分布特徵相似，但多环芳烃的组成和质量分数不同；煤化程度增加，原煤多环芳烃质量分数和毒性当量质量分数减小，煤气化多环芳烃质量分数先增后减，毒性当量质量分数与煤化程度呈线性关系；部分煤种气化多环芳烃的质量分数高於原煤多环芳烃质量分数，且煤气化多环芳烃的种类分为原煤未分解的多环芳烃、热解合成的多环芳烃、自由基高温缩合生成的多环芳烃。
