Distribution of trace elements in coal and coal fly ash and their recovery with mineral processing practices: A review

Today coal is among the most important energy sources. In order to meet the world's energy demands, low-calorie lignite with a high ash content is generally used in the large capacity coal-fired thermal power plants. As a result of coal firing, wastes such as fly ash, slag, and flue gas are also produced. Subsequently, toxic trace elements within coal are transferred to wastes such as slag, fl...

Molecular Catalytic Coal Liquid Conversion

In this Quarter, the research was focused continually on the two general tasks: Task 1, molecular organometallic catalysts for hydrogenation and Task 2, organic base catalysts for arene hydrogenation and the hydrotreating of the coal liquids. With regards to Task 1, the [ 1,5-HDRhCl] suffer catalyst system has been investigated in detail to improve its performance. In the presence of CTAB ([CTA...

Economic Growth and Coal Consumption in China

In this paper, we used the methods of cointegration and granger causality estimation to test the relationship between China’s coal consumption and real GDP based on the data of 1978~2010, the results show that the real GDP and coal consumption have no granger causality, and do not have a long run cointegration, which is different from the existing discovery. Because of following reasons, first ...

A review of simultaneous ultrasound-assisted coal flotation

Ultrasound can be used both simultaneously or as a pretreatment technique for flotation to produce higher combustible recoveries, higher heat values, and lower ash data from raw hard coals. The recent research works have indicated that modifying coal surfaces, especially physical surface cleaning with the help of the cavitation process created by power ultrasound at certain frequency and time i...
