1. Impurity content and composition of the raw materials 2. Reaction temperature 3. Reaction pressure 4. Hydrogen partial pressure or hydrogen-to-oil ratio 5. Space velocity 6. Catalyst selection and packing efficiency
1. Reaction temperature: the higher the temperature, the greater the degree of reaction； 2. The higher the air velocity, the greater the reaction depth ；
1. Reaction temperature. It is generally adjusted by the preheating temperature of the raw materials and the catalyst circulation rate. 2. The type and activity of the catalyst, as well as the addition of other additives, also affect the extent of the reaction, such as propylene additives and desulfurizing agents. 3. Use of terminators. Reaction time. Reaction time is related to the length of the riser and the rising speed. Furthermore, changes in the properties of crude oil have a significant impact on depth (under the same operating conditions); operators should promptly analyze raw material data and product data to adjust the process parameters. There is also reaction pressure
Factors that affect the reaction depth include reaction temperature, catalyst activity, reagent-to-oil ratio, reaction time, and reaction pressure.
① As the reaction temperature increases, the depth increases； ② Catalyst activity increases, and the depth increases as well ； ③ Changes in the properties of crude oil ； ④ The purity of recycled hydrogen increases, and its depth grows ； ⑤ The reaction pressure increases, and the depth increases as well ； ⑥ As the reactor space velocity increases, the depth decreases
The main factors affecting the reaction depth include reaction temperature, catalyst activity, reagent-to-oil ratio, reaction time, and reaction pressure
As the reaction temperature increases, the depth increases. The catalyst activity increases, and the depth increases as well. Changes in the properties of crude oil. The purity of recycled hydrogen increases, and its depth increases as well. As the reaction pressure increases, the depth increases as well. As the reaction space velocity increases, the depth decreases.
As the reaction temperature increases, the depth increases. The catalyst activity increases, and the depth increases as well. Changes in the properties of crude oil.
1. The purity of recycled hydrogen increases, and its depth increases as well. 2. The reaction pressure increases, and the depth increases as well. 3. As the reaction space velocity increases, the depth decreases.
