The distinct features of type PPP deoxidizers are: To propylene with the unstable double bonds, it is not accompanied by any secondary reaction such as addition reaction, polyreaction, oxidation reaction and so on. That is why it is special for liquid phase propylene deoxidizing. The adsorption of type PPP to hydrogen (H2) is weak, so when it is reactivated by H2, only little H2 is adsorbed, thus the temperature runaway caused by hydrogenation reaction does not occur while the transportation of propylene, therefore it is safe and reliable. Deep deoxidizing, high capacity of operation oxygen, long useful time are also its characters.
