The high sulfur coal from Jiexiu in Shanxi is used in this experiment and the influence of removing pyritic sulfur by adding different pyrites depressors on the process of agglomeration was explored in this study,The experiment result shows that adding pyrites depressors on the process of oil agglomeration can improve the sulfur-removing rate.

油团聚是以脱除煤中灰分为主的团聚技术，脱硫的效率很低，采用山西介休的高硫煤，探索在油团聚过程中加入不同的黄铁矿抑制剂(巯基乙酸、重铬酸钾、高锰酸钾)对脱除煤中黄铁矿硫的影响。结果表明加入黄铁矿抑制剂对脱硫效率有一定程度的影响

These experiment investigztions indicate: When coal is under high heating pyrolytic condition, the pyrite in coal decomposes very quickly, some amount of pyritic sulfur is transformed to organic sulfur and 〓 char, the volatile waterial in coal will restrain the transformation.

根据这一些试验研究得出：煤在快速热解条件下，煤中的黄铁矿的热分解极快，黄铁矿热分解的一部分硫转化成有机硫而存留在残炭中，煤中挥发份对这种硫的转化起抑制作用。

It has been summarized that domestic coal-blending study in ten years, included two major problems concerning coal blending ratio and pyrogenation and combustion of mixed-coal.

The evolution degree of sapropel type Kerogen and humic type Kerogen may be defined by the feature of gas components.But this method is not applicable for mixing gas source material including sapropel type Kerogen and humic type Kerogen.

依据天然气组分特征可以判别煤型气和油型气这两种极端类型天然气的母质转化程度，但对于既有煤型气又有油型气或介于煤型气和油型气之间的天然气则不适用。

From the research of the kerogen carbon isotopes of the coal-measure strata in some basins of China (the Carbo-Permian in the Ordos basin, the Triassic in the Sichuan basin, the Jurassic in the Jungar basin and Turpan-Hami basin, the Tertiary in the Yingqong basin) it can be indicated that the Type Ⅲ kerogen has a wide δ〓C range from -21. 2‰ to -27. 6‰, averaging -25‰, which is more enriched in 〓C than sapropel and mixed kerogens.

对我国一些含煤盆地（陕甘宁石碳－二叠、四川三叠系、准噶尔侏罗系、吐哈侏罗系、莺琼盆地第三系）的煤系地层干酪根碳同位素研究表明，煤系地层的干酪根碳同位素组成δ〓C值分布范围为－21.2～－27.6‰，说明其变化范围较宽，平均值为－25‰左右，相对腐泥型干酪根和混合型干酪根较明显地富重碳同位素。

Meanwhile, the differences of prominence about effects of factors and best technological conditions are found by the means of perpendicularity analysis.(2) The properties of semicoke from North Shannxi and coke from Shanxi are compared.

An experimental study was made on the method of preparing sulphonated coal .

研究了褐煤制备磺化煤的方法，同时研究了磺化温度、磺化时间、酸煤比等因素对产物磺化煤的离子交换活性的影

The results show that although the amount of organic sulfur did not change remarkably, the H2S evolved from the oxidized sample decreased, COS and SO2 evolved increased significantly. This indicated that the aliphatic sulphides were selectively oxidized to sulphoxide and sulphone.

结果表明，空气和HNO3氧化后，尽管煤中有机硫总量变化不大，但煤中H2S的释放量有所下降，而COS和SO2的生成量明显增加，这说明氧化作用使得煤中弱的有机硫变成S=O和SO2结构。
