What are the requirements for diesel hydrorefining catalyst selection?
1. It depends on the nature of the raw materials. 2. Product quality requirements and direction 3. Process flow 4. The economic strength of the enterprise meets the above requirements: Require: a. The catalyst has better activity b. Better stability c. Better selectivity d. Better mechanical strength It is also necessary to pay attention to the active metal components, specific surface area, and pore volume of the catalyst.
1. The catalyst can be widely used in the hydrorefining of straight-run kerosene fractions, straight-run diesel fractions, secondary-processed diesel fractions (for catalytically cracked diesel with high sulfur and nitrogen content), and secondary-processed gasoline (saturation of coke gas olefins). They all show good performance:) It can produce low-sulfur and high-quality diesel, and the product quality meets the factory requirements. 2. The catalyst has better stability during long-term operation. 3. It should have the characteristics of low reaction temperature, large air velocity, and low hydrogen-to-oil ratio.
