Abstract (en)
[origin: WO2020021514A1] Systems and methods for producing light olefins and aromatics from light naphtha are disclosed. The light naphtha is fed to a first catalyst riser to crack the C5 to C7 hydrocarbons in the light naphtha stream. The cracked naphtha stream is fractionated to produce a stream comprising primarily C4 to C6 hydrocarbons or a stream comprising primarily C5 to C12 hydrocarbons. When the stream comprising primarily C4 to C6 hydrocarbons is fed to the second catalyst riser, the product stream from the second riser comprises light olefins as the main product. When the stream comprising primarily C5 to C12 hydrocarbons is fed to the second riser, the product stream from the second riser comprises aromatics as the main product.
