Fraction oil oxidation desulfurizing catalyst and its preparation

Abstract

The fraction oil oxidizing and desulfurizing contains VIB, and VIII, IVB or VB metal oxide loaded onto porous acid carrier, and has VIB metal content 10-30 wt%, and VIII, IVB or VB metal content 1-8 wt%. The preparation process of the catalytic includes preformation of the transitional acid carrier, once soaking the carrier in the solution of the said metals, drying and roasting. The catalyst is used for the oxidation and desulfurization of sulfur containing hydrocarbon fraction oil in the presence of oxidant and alcohol, and is especially suitable for the oxidation and desulfurization process of light oil products.

Description

1. Technical field:

[0001] The invention relates to a distillate oil oxidation desulfurization catalyst and a preparation method thereof. More specifically, it relates to a catalyst capable of effectively oxidizing organic sulfur present in sulfur-containing hydrocarbon distillates in the presence of oxidants and alcohols and a preparation method thereof. 2. Background technology:

[0002] With the improvement of people's awareness of environmental protection, the problem of vehicle exhaust pollution has been paid more and more attention. Europe, the United States, Japan and China have successively proposed new standards for various hydrocarbon distillate oils, which have strict regulations and restrictions on sulfur content, benzene content, aromatics content, olefins content and oxygen content.

[0003] As we all know, the usual method to reduce the sulfur content, olefin content and nitrogen content of various hydrocarbon distillates is to use hydrogenation saturation te...
