Does high-molecular-weight polymer stabilize coal water slurry?

The stability of coal water slurry (CWS) is a significant factor affecting its storage and transportation. However, the understanding of the mechanism of high-molecular-weight polymer used as stabilizers in CWS is still limited.

Does polymer containing wastewater from oil production affect coal water slurries?

Effects of polymer containing wastewater from oil production on preparation and properties of coal water slurry, Clean Coal Sedimentation stability and rheology of coal water slurries Effect of coal particle size distribution, volume fraction and rank on the rheology of coal–water slurries Fuel Process. Technol., 85 ( 2004), pp. 241 – 250

Does carboxymethyl cellulose affect the stability of coal water slurries?

The effect of carboxymethyl cellulose (CMC) on the stability of coal-water slurries Effect of stabilizing additives on the stability of coal water mixtures Improving stability of concentrated coal–water slurry using mixture of a natural and synthetic surfactants Fuel Process. Technol., 113 ( 2013), pp. 41 – 51

Which polymer has a high affinity with polycyclic aromatic hydrocarbon?

PAM is a long-chain linear structure polymer with carbon-carbon double bonds, which has a high affinity with polycyclic aromatic hydrocarbon of coal surface . PAM can be adsorbed on the surface of coal particles due to this driving force, and the side chain groups are exposed to the surrounding solution.

What is the dynamic stability index of coal water slurry?

The vertical axis of the graph is the dynamic stability index of coal water slurry, which is also regarded as the sedimentation rate of slurry after oscillation. Moreover, the horizontal axis denotes four different slurry samples. Fig. 5. Dynamic stability performance of CWS with different PAM.
