Requirements for the four components of catalytic raw materials
Thread Content
Dear heroes, it is an indisputable fact that catalytic raw materials are getting heavier and heavier. The current problem to be solved is to ensure a relatively ideal yield of catalytic products, such as 38% gasoline, 21% diesel, 16% liquefied gas, 7% oil slurry, and 3% dry gas. What are the corresponding requirements for the proportion of the four components? In other words, how high can each of aromatic hydrocarbons, colloids and asphaltenes be?
Hydrogen content is an important parameter for the cracking properties of raw oil and is generally controlled to be greater than 12%. The higher the saturated hydrocarbon content and the lower the gum and asphaltene content, the higher the hydrogen content and the higher the yield. Below are the statistics of our catalytic workshop for reference. Saturated hydrocarbon% 58.98 54.46 59.42 60.2 Aromatic hydrocarbon% 30.51 32.02 26.05 23.57 Asphaltenes + colloid% 10.51 12.9 11 13.83 Total liquid rate % 78.3 75.4 81 81 This post was last written by maysee Edited at 2007-12-26 17:11 ]
To have good feedstock oil, you also need to have high catalyst activity. Heavy metals in raw materials can also affect yield issues. Of course, the four components are an important parameter and are beneficial to the adjustment of working conditions.
Thank you, brother, thank you very much. I am from Haihua, Shandong. If you come to Weifang and leave a message in advance, I will treat you to dinner!
