| 1 | It is known as catalytic cracking. | |
| 2 | The high-temperature butterfly valve is a key valve in the fluid catalytic cracking unit. | |
| 3 | They have good heat transfer efficiency with better resistance to thermal cracking and chemical oxidation. | |
| 4 | The latest desulfurization technologies of Fluid Catalytic Cracking (FCC) gasoline are introduced. | |
| 5 | The GOR-DQ catalyst for reducing FCC gasoline olefinicity was designed on the basis of chemical reactions in catalytic cracking conditions. |
