What causes the high viscosity of coal tar?
Thread Content
Coal tar viscosity: 4-6, toluene insolubles: 10-14. What is the reason for this?
Possible reasons: 1. Coal tar has been mixed in； 2. High coke powder content
What are the main sources of coal tar pitch? Thank you
Check if the temperature in the space above the furnace is too high
The tar-toluene insolubles are high if it exceeds seven; usually, they are around three or four. It’s a coking issue; it’s necessary to keep the temperature in the furnace top area under control.

Check the temperature in the coke oven roof space, and reduce it appropriately.
Emulsifiers can be used. . Using 800 grams per ton of ammonia water, it will take about 3 months for things to return to normal
