Catalyst for C4/C5 Saturation Hydrogenation
C4/C5 saturation hydrogenation recovery of butanes and pentanes is commercially proven process with many years of operating experience worldwide for total hydrogenation of C4s, C5s or C4/C5 mixture. In the process, C4s or C5s from an ethylene plant, refinery or MTO unit are hydrogenated to convert the contained olefins, alkynes, and dienes to primarily paraffins.
The conversion of the olefins, acetylene and dienes is quite high with >99% saturation being readily achieved on the outlet of the saturation hydrogenation unit (SHU). The product from the SHU can be used as steam cracker feedstock or be sold as LPG.
