TD-815 to improve the octane / propylene additives is a kind of high-performance solid cocatalyst used in the refining catalytic cracking unit to improve the octane number of gasoline. When the addition of TD-815 octane additive reaches 5% -10% of the system's system, the octane number RON of the catalytic gasoline can be increased by 1.0 to 2.0 percentage points, which can improve the product distribution: improve the yield of liquefied gas About 2 to 3 percentage points, of which propylene increased by about 1 percentage point, gasoline + diesel yield decreased by about 2 percentage points, dry gas, oil slurry, coke yield and basically mixed before the device, the total liquid The rate remains basically unchanged.
