ADSORBENT FOR FEED AND PRODUCTS PURIFICATION IN BENZENE SATURATION PROCESS
摘要:
The service life and deactivation rate of a benzene saturation catalyst is improved through use of a new sulfur guard bed containing a chloride additive. This sulfur guard bed, which contains supported CuO material having an increased resistance to reduction, shows such improvement. Thus, the danger of run-away reduction followed by a massive release of water and deactivation of an isomerization catalyst is practically eliminated. The fact that the guard bed material preserves the active metal phase-copper in an active (oxide) form is an important advantage leading to very low sulfur content in the product stream. The sulfur capacity per unit weight of sorbent is also significantly increased, making this sorbent a superior cost effective sulfur guard product. The guard bed is effective in treating mixed phase feed streams.
