Deeply processed products of coal tar pitch
Thread Content
Products derived from coal tar pitch that have been industrialized in China or are currently in the pilot production stage, such as carbon fibers, mesophase carbon microballs, needle coke, impregnated pitch, and modified pitch, are all topics that can be explored in more detail.

As far as I know, the ones that are produced industrially include modified asphalt, impregnated asphalt, and needle coke.
Using medium-temperature asphalt or soft asphalt, the following products can be produced: modified asphalt, hard asphalt, special medium-temperature asphalt, anti-corrosion coatings, road construction oil, impregnating asphalt (without QI), mesophase asphalt, asphalt without a mesophase, needle coke, carbon microspheres, carbon fibers, special activated carbon, and other products.
Our factory uses two reactors in series to produce modified asphalt, which features simple operation and high product quality. :lol
By the way, I’d like to ask upstairs: how does your factory handle the fumes generated by modified asphalt? ? ? Our factory is too close to residential areas; we haven’t dared to operate it for several years. .
The asphalt flue gas is drawn into a scrubber tower equipped with a spray system for washing oil, where it comes into counterflow contact with the washing oil to absorb the oils present in the flue gas. To achieve the goal of evolved flue gas.
Modified asphalt is produced using two reactors, resulting in too low output. I estimate your scale is below 100,000 tons.
The main products of asphalt processing include modified asphalt, hard asphalt (Cooper’s process), needle coke, carbon fiber, and carbon microspheres. Among these, needle coke, carbon microspheres, and carbon fiber offer good cost-performance ratios, and venturi tubes are effective for absorbing asphalt fumes.
