O is the oxygen content in wt, dry basis, C is the carbon content in wt, dry basis, H is the hydrogen content in wt, dry basis, S is the sulphur content in wt, dry basis and Ash is the ash content in wt dry basis. The calorific value was obtained by using the equations developed by Sheng and Azevedo, 2005 as follows Eq2.
May 28, 2021 Both surface and underground rocks in nature often undergo repeated drying and wetting. The dry-wet cycle is a weathering effect that includes physical and chemical processes, which has varying degrees of degradation effects on the physical and mechanical properties of rocks. This paper analyzes and discusses this kind of rock degradation based on the existing literature data.

Jun 29, 2007 A new isolate of Trichoderma atroviride has been shown to grow on low rank coal as the sole carbon source. T. atroviride ES11 degrades 82 of particulate coal 10 g l1 over a period of 21 days with 50 reduction in 6 days. Glucose 5 g l1 as a supplemented carbon source enhanced the coal solubilisation efficiency of T. atroviride ES11, while 10 and 20 g l1 glucose decrease coal ...
Apr 06, 2021 Results showed that 1 The coal moisture decreased gradually with the drying time and increased with the soaking time. When coal is soaked in high pressure water 520 MPa, the moisture content in coal will increase from 2.60 to 3.85 with the increasing of water pressure.
May 01, 2007 Once dry, the concentrate is homogenized by grinding for subsequent steps in kerogen preparation. As discussed below, kerogen becomes prone to oxidation once minerals have been destroyed. Accordingly, all the above operations are performed under a flow of N 2 and the kerogen concentrate is stored under an inert gas atmosphere before further ...
