Special catalyst for MGD process RGD-1 The MGD process uses heavy oil as raw material, uses FCC process equipment to produce more liquefied gas and diesel, and can significantly reduce the olefin content of gasoline. RGD-1 catalyst is a specialized catalyst for this technology. Compared with conventional catalytic cracking technology, MGD process technology has the following characteristics: 1. Adopt staged feeding and use crude gasoline to control cracking technology. Through the secondary reaction of crude gasoline in a dense-phase ascending bed, on the one hand, the low-carbon olefins in the gasoline are cracked to reduce the olefin content of the gasoline. ； On the other hand, by adjusting the reaction environment and reaction severity of the cracked raw materials, the generation and retention of diesel fractions are increased. 2. The yield of liquefied gas and diesel is significantly higher than that of conventional FCC technology. 3. The olefin content in gasoline can be greatly reduced, and the octane number of gasoline can be increased to a certain extent. 4. High-value products (liquefied gas + gasoline + diesel) are equivalent to conventional FCC technology. 5. Flexible adjustment of production operations. Different production plans can be selected according to market demand and product distribution can be flexibly adjusted.
