摘要
煤中微量元素的含量水平是煤洁净化利用的参考标准之一,对1 300多个西北侏罗纪煤样微量元素进行分析。结果表明,西北侏罗纪煤中微量元素整体含量偏低,仅少数微量元素在西北局部区域有明显富集,如Ba在鄂尔多斯盆,U和Mo在伊利盆地,V、Co、Y在准噶尔盆地,W在柴达木盆地;各盆地微量元素整体含量为柴达木盆>准噶尔盆地>伊犁盆地>鄂尔多斯盆地>塔里木盆地;西北地区,早侏罗纪微量元素整体含量较中侏罗纪高。
The content of trace elements in coal is one of the reference standards for coal clean utilization, and more than 1300 Jurassic coals from Northwest, China were analyzed. It is concluded that the total content level of trace elements in the Jurassic coal in the northwest is low, and only a few trace elements are obviously enriched in local areas in Northwest Jurassic coal, such as Ba in Ordos basin, U and Mo in Yili basin, V, Co and Y in Junggar basin and W in Qaidam basin. The total trace elements content in each basin shows the trend of Qaidam basin〉Junggar basin〉Yili basin〉Ordos basin〉Tarim basin. In the Northwest of China, the total content of trace elements in early Jurassic is higher than that in middle Jurassic. The research results lay a theoretical foundation for the clean utilization of Jurassic coal in Northwest China.
