Effect of Cu(NO₃)₂ and Cu(CH₃COO)₂ Activating Additives on Combustion Characteristics of Anthracite and Its Semi-Coke

Energies, 2020
The process of anthracite and its semi-coke combustion in the presence of 5 wt.% (in terms of dry salt) additives of copper salts Cu(NO3)2 and Cu(CH3COO)2 was studied. The activating additives were introduced by an incipient wetness procedure.
