Pyrolysis Gasoline 1st Stage Hydrogenation Catalyst

Pyrolysis Gasoline 1st Stage Hydrogenation Catalyst

1. Introduction
Catalyst LSDLI-1 is used for hydrofining pyrolysis gasoline to stablize the gasoline by the hydrogenation of triple bonds and double bonds, and to remove impurities including S, N, and O from the gasoline through hydrodesulfurization (HDS), hydrodenitrogenation (HDN), and hydrodeoxygenation (HDO). The product is good for extracting arenes
