A novel method for removing quinoline insolubles and ash

Jun 01, 2012· Highlights Electrostatic field has been successfully applied to the removal of QI and ash in coal tar pitch. Removal efficiency for QI and ash is 100 wt.% and 80.5 wt.%, respectively. Comparing with centrifugal method for removal of QI and ash, electrostatic field decreases by 88% of energy consumption. Equilibrium between desorption and deposition rates can be arrived with EF lasting time

Coal tar Wikipedia

Coal tar is a thick dark liquid which is a by-product of the production of coke and coal gas from coal. It has both medical and industrial uses. Medicinally it is a topical medication applied to skin to treat psoriasis and seborrheic dermatitis (dandruff). It may be used in combination with ultraviolet light therapy. Industrially it is a railway tie preservative and used in the surfacing of roads.

How is Crude Coal Tar Derived 1

The coal-to-coke transformation takes place as follows: The heat is transferred from the heated brick walls into the coal charge. From about 375°C to 475°C, the coal decomposes to form plastic layers near each wall. At about 475°C to 600°C, there is a marked evolution of tar, and aromatic
