Webb25 feb. 2024 · A catalyst, by definition, is a substance that enhances a chemical reaction. In the refining industry, catalysts are extensively used in many upgrading processes. One common upgrading process in refineries is the Fluid Catalytic Cracking unit (FCC) unit, which converts heavier distillation cuts into lighter, more profitable products, such as … WebbTwo important continuous slurry processes are used the Exxon (Vistanex) process with A1C13 catalyst and the BASF process (Oppanol), which polymerizes isobutylene dissolved in ethylene (in a ratio about 1 2) in the presence of BF3. Ethylene serves as the internal cooler. [Pg.774]
