Abstract
The present invention relates to a bimetallic mercaptan conversion catalyst for sweetening liquefied petroleum gas at a low temperature, which is prepared by using an Al2O3—SiO2 composite oxide as a carrier to support bimetallic active components vanadium and nickel. The bimetallic mercaptan conversion catalyst has a proper specific surface area and more metal active center sites, and has advantages of simple preparation, an efficient mercaptan conversion ability even at a low temperature, and causing no saturation and polymerization of olefins. The bimetallic mercaptan conversion catalyst exhibits superior mercaptan conversion performance in LPG sweetening, has strong adaptability to starting materials, and can also nearly completely remove trace carbonyl sulfide contained in LPG.
