What is the difference between coal tar and anthracene oil hydrogenation?
Thread Content
1. What are the differences in the properties of coal tar and anthracene oil as hydrogenation feedstocks? 2. What are the differences in hydrogenation operations?
The range of diesel fuels is too wide: straight-run, catalyzed, coked… Generally speaking, coal diesel fuels consist mainly of straight-chain structures, while anthracene oil contains three benzene rings. Hydroprocessing of coal diesel fuels is stable, with minimal temperature rise in the reactor, making it easy to operate. For anthracene oil, do you want it desulfurized or saturated? If it becomes saturated, the reaction temperature rises sharply, hydrogen consumption is high, and it is difficult to operate.
We carry out anthracene oil hydrogenation, hydrogenation refining, and cracking; later on, coal gas was also blended in, but the feed oil distillation column is difficult to operate as it tends to clog with coke and block the trays
The diesel hydrorefining process is stable, and the technology is relatively mature
We have additives to address tray blockages (capable of online descaling for different operating conditions); if you’re interested, feel free to contact me at QQ627339853
