摘要: An FCC process and apparatus may include injecting hydrocarbon feedstock at different radial positions inside a riser. Multiple distributors be used to position the openings for multiple positions. In addition, away from riser peripheral wall elevations along or extending up bottom. The opening introduce across larger area of cross-section riser, which improve dispersion mixing with catalyst. Improved increase conversion feedstock. Larger units generally have greater diameters that cause problems decrease ability mix Injecting in mixing.
