The raw material preheating temperature is related to the design of the device, which basically determines the raw material preheating temperature. However, the crude oil processed is now inferior. In order to reduce naphthenic acid corrosion, some devices deliberately lower the preheating temperature to about 210 degrees. In order to achieve the same reaction temperature, the catalyst circulation volume must increase! The bed temperature is related to the catalyst storage amount, catalyst oil ratio, and processing raw materials. It depends on the actual operation of your device. The size of the refractory depth directly affects product distribution. If you re-refiner oil slurry, the liquid yield may increase simply in terms of yield! After all, when the reaction temperature is high, the thermal cracking tendency increases, and the dry gas and coke yields increase. If possible, see if we can improve the nozzle. Select the cs kh (these two are more commonly used in China) series, which may be more effective and require less investment! Here we are looking to see if we can optimize the catalyst and find a specialized agency to help you select it. You may get unexpected results.
