褐煤

The corrosion acton of carboxyl and phenol hydroxy of lignite and peat on low-alloy steel was studied.

研究了褐煤和泥炭中羧基和酚羟基对低合金钢27SiMn的腐蚀作用。

The results indicate that the surface area of coal is related to the coal particle size, the maceral content and the adsorbate used.

在上述工作基础上，选用孔隙结构发达的大雁褐煤作为原料，探讨了制备空分用炭分子筛的可能性。

This method and systems are also used for other volatile-rich fuels such as brown coal and bituminous coal.

同样适用于研究褐煤、烟煤等高挥发分燃料的输送特性。

The corrosion rate of plain carbon steel contacted with higher coalification such as anthracite coal is 2 to 3 times larger than that in brown coal .

在相同的其它条件下，碳钢的腐蚀速率随接触的煤的煤化度提高而增加，与发育良好的无烟煤接触的碳钢的腐蚀速率是在煤化度相对较低的褐煤中的2～3倍以上。

The humic acid content of lignite varies in a wide range of from 3.3 to 67.8%; it decreases sharply with increasing degree of coalification.

褐煤腐植酸含量变动较大，在3.3—67.8%；随着煤化程度增加，腐植酸量有明显减少的趋势。

The results from comparative analysis show that the coal has a large surface area. Particularly, there are a lot of semi-opened microspores. These two characters are the main reasons that lignite has high moisture and is hard to dewater.

实验结果表明，印尼褐煤比表面积很大，尤其是存在大量的一端封闭一端开放的孔隙结构，这是其含水量高、易吸水回潮并不易脱水的主要原因。

Aimed at the difficulty of heavy oil development and the high price of general surfactant as emulsifying agent,the probability of sodium humate as emulsifying agent was discussed.

针对稠油油藏开采难度大，采用常规乳化用表面活性剂费用高的现状，研究廉价的褐煤腐植酸钠作为稠油乳化剂的可能性。

This paper describes the principles and methods of extracting humic acid product from lignite.

论述了褐煤中提取腐殖酸产品的方法及原理。

We use China's best production of lignite or peat activity humic acid sodium .

我们生产的活性腐植酸钾是采用中国最好的褐煤或泥炭。

The Company has domestic production capacity of approximately 2 million tonnes per annum of lignite coal.

公司在泰国国内的褐煤年产量约为200万吨。

Since historical times,England ,where the early inhabitants were Celts, has been conquered three times .

从有历史以来，英国，在此地早期居住的是凯尔特人，已经被征服了三次。
