Does anyone have any academic materials on needle coke? Thank you, it’s urgent! ! The facility has not yet started operations; it was just established and is currently in the construction phase. The general process involves using catalytic slurry for supercritical extraction, hydrogenation, coking, and calcination to produce needle coke. I haven’t worked with this process; I’ve only been involved in hydrogenation. I don’t understand anything; I want to find some materials to learn a bit first*
All such materials are kept hidden like treasures； If I want to share it, I’ll have to wait another three or four years.
Which device? Is it technology from China University of Petroleum?
You can first study delayed coking
Why is hydrogenation still needed here? Is it for the purpose of desulfurization?
Yes, desulfurization is also required. The oil slurry used before was purchased from outside, and its quality could not be guaranteed
So what solvent is used in this supercritical extraction?
Xinjiang Hongfu? Calcination is the simplest. Just take a look at the carbon rotary kiln
There are only a few oil-based projects under construction, and the technology used in them is now quite mature
