Experts in catalysis, how can we increase the gasoline yield and reduce liquefied gas production?
Increase the reaction temperature and observe the increase in gasoline yield until it reaches a maximum value; however, the reaction temperature cannot be increased indefinitely, as too high a temperature will result in higher yields of gas and coke； Fractionation reduces the production of diesel by adjusting parameters such as the intermediate temperature, top temperature, the amount of stripping steam used in the light diesel stripping tower, and the boiling range ； Stabilization should aim to minimize the bottom temperature of the stabilizer tower, while ensuring that the saturated steam pressure remains within acceptable levels, in order to produce more gasoline and less liquefied gas. :lol
The temperature here can be increased relatively, with quench oil (or other medium) injected at the top of the riser. In fractional distillation, the dry point of the crude gasoline is carefully controlled to ensure the integrity of the separated components. Stabilization here can be achieved by appropriately lowering the reboiler temperature; however, from a safety perspective, it is necessary to prevent light hydrocarbon components from entering the gasoline mixture in order to avoid safety incidents! Models that are conducive to improving gasoline components can be used for catalysts or additives!
Stability can be achieved by appropriately lowering the temperature of the reboiler. However, from a safety perspective, it is necessary to prevent light hydrocarbon components from entering the gasoline mixture, so as to ensure that the saturated vapor pressure of the stable gasoline remains within acceptable levels and does not become too high
It is a rather large-scale systematic project; for example, selecting the appropriate type of process, suitable catalyst formulations, the properties of raw materials, determining the right reaction temperature, fuel-to-oil ratio, and reaction time – in short, it’s necessary to get the reaction depth under control. Additionally, there is the optimization of distillation and stabilization processes
Do you use heavy oil catalysis or wax oil catalysis?
Determine the specific plan based on the actual conditions of the device! The properties of the raw materials are fundamental. Many specific measures were mentioned above. One more point: increase catalyst activity!
