A New Clean Coal Technology by Mild Modification at Low Temperature

在订购开发新的治疗方法时，生产清洁和反应性煤炭的方法，我们完成了后续项目：（1）煤炭液体氧化阶段的发展。（2）通过预处理去除铝合金金属和硫酸盐的表现。（3）Analysis of cross-linking reaction of pretreated coal（4）A new co-liquefaction of coal and pretreated coal.第一，它找到了一个部分的芳香环were ruptured into aliphatic structures and a large amount of hydrogen was introduced in the coal through the liquid phase oxidation with H-D22-D2。同样地，小分子脂肪酸的大剂量已经被恢复，这表明氧气被煤炭从一种有价值的化学品中移除。这些预先处理的煤炭被用于幽门螺杆菌和燃烧，然后对alkali金属蒸汽和硫酸盐的发射概况进行了审查。他们的费用被戏剧性地取消了通过H-E D22-E D2 O-E D22-E D2氧化，下一步，我们审查了被预先处理的煤炭的反应性。我们分析了在预处理煤炭升温期间交叉反应的动力学因素。“COOH组通过预处理方法在400 ° C之间分解成交叉链接，但在多种条件下预先处理的煤炭没有交叉链接，因为COOH被一种小分子脂肪酸的形式去除。”既然它也发现了一种预先处理的煤炭在200 ° C的温度下很容易溶解，我们就提供了一种可处理的煤炭和可处理的煤炭的协同作用，以利用这一特性。通过将预先处理的煤添加到溶液的一部分中，这是明确的，因为提议的方法是有效的，因为一种预先处理的方法是生产清洁和反应性煤。

In order to develop a new pretreatment, method for producing a clean and reactive coal, we performed the following items :(1)Development of liquid phase oxidation of coal.(2)Performance of the removal of alkali metal and sulfur through the pretreatment.(3)Analysis of cross-linking reaction of pretreated coal(4)A new co-liquefaction of coal and pretreated coal.First, it was found that a part of aromatic rings were ruptured into aliphatic structures and a large amount of hydrogen was introduced in the coal through the liquid phase oxidation with HィイD22ィエD2OィイD22ィエD2. Simultaneously, a large amount of small molecule fatty acids were recovered, indicating that the oxygen removed from coal by a from of valuable chemicals. Thus pretreated coal was served to the pyrolysis and combustion, then the emission profiles of alkali metal vapor and sulfur was examined. Their amounts emitted dramatically decreased through the HィイD22ィエD2OィイD22ィエD2 oxidation.Next, we examined the reactivity of the pretreated coal. We analyzed the kinetics of the cross-linking reaction during the heating of pretreated coal. The COOH groups introduced through the pretreatment was decomposed to cross-link by 400℃, but the pretreated coal under severe condition was not cross-linked because the COOH was removed by a form of a small molecule fatty acids. Since it was also found that the pretreated coal was easily dissolved by solvent at 200℃, we present a co-liquefaction of coal and pretreated coal by utilizing this property. The liquefaction yield increased by adding the pretreated coal in place of a part of solvent.Thus it is clarified that the proposed method is effective as a pretreatment method for producing a clean and reactive coal.
