Increase gasoline yield

Operation can increase the reaction temperature and enhance the reaction depth; additives can be used to boost the yield of liquid products, and additives aimed at improving catalyst activity can also be employed!

The original poster’s information is not detailed, making it difficult to answer your question. At the very least, the general details of the device need to be explained clearly.

In simple terms, increasing the oil-to-agent ratio, raising the reaction temperature and catalyst activity, and reducing the reprocessing ratio can all increase gasoline yield. However, which specific conditions to adjust and how to do so depends on the specifics of each plant’s equipment; in addition, the distillation conditions can also be changed. .

Improve the distillation accuracy of the distillation tower, adjust operations, and produce at the limit.

Raise the dry point of gasoline, add other components that can be incorporated into gasoline (naphtha, MTBE, etc.), and also optimize the reaction processes based on the specific characteristics of the own facility.

1. Using purchased naphtha as a riser terminator can increase gasoline production and boost added value. 2. Select appropriate catalysts and additives. 3. Reduce the dry point of gasoline while ensuring that the flash point of light diesel meets the requirements. 4. Maximize the reaction depth, provided that the semi-coke is of appropriate quality.

To increase gasoline yield, in terms of catalysis, it simply means organizing production using a gasoline-based approach; those familiar with catalysis understand this well. . . In atmospheric and vacuum distillation, it’s sufficient to cut more at key points to ensure that the boiling range meets the requirements. . . The same principle applies in coking as well. . . . :lol

The main goal is to increase the reaction depth, as deep cracking converts large molecules into smaller ones; it also aims to improve the precision of the distillation column. Regarding the distillation tower, increase the top pressure appropriately to lift the light components upward.

Methods such as increasing the reaction temperature, enhancing catalyst activity, and raising the reagent-to-oil ratio can be used to increase the degree of reaction, but it is also necessary to consider the balance of yields for various products; sometimes increasing the gasoline yield by a certain amount may result in a decrease in diesel yield by several points. In the operation of distillation, the temperature at which the oil and gas are discharged can be increased appropriately to raise the dry point of gasoline as much as possible; however, an increase in the dry point leads to a higher sulfur content in gasoline, so adjustments need to be made based on the actual conditions of the plant. The most effective approach is to improve the quality of raw materials

Are there any additives that can increase gasoline production? Please let me know

There is indeed a demand for higher gasoline production in the market at present; recently I visited several refineries, and those owned by Sinopec in particular are requesting an increase in gasoline output. Here I will only introduce the measures to increase gasoline production in catalytic units: 1. Process adjustment: increasing the catalyst-to-fuel ratio and enhancing the activity of the balancing agents, etc ； Many people upstairs have already given their introductions. 2. From the catalyst side: stop using propylene additives or liquefied gas-producing additives ； Contact the catalyst manufacturer to adjust the catalyst formula, specifically by reducing the amount of shape-selective molecular sieve in the catalyst and increasing the amount of highly active molecular sieve ； That is, a catalyst with high gasoline yield is selected. I have been doing this kind of work these past two weeks.
