Description
Technical field
The present invention relates to a kind of composite catalyst SiO2The preparation method of -0.1CuO.
Background technology
2005, sulfur content ＜ 50mg/L in European Environment laws and regulations requirement diesel oil, 2006, U.S. environment regulation required sulphur
Content ＜ 15mg/L.2013, China proposed National V emission standard again, i.e. sulfur content is not higher than 10mg/L, and new standard is carrying
Height illustrates that country increasingly payes attention to low-sulfur oil and super-low sulfur oil.Under new standard, traditional hydrodesulfurization（HDS）Technique is grasped
Make condition harshness, need the operating conditions such as high temperature, high pressure, long residence time, more hydrogen and catalyst, improve HDS at
This.One of non-hydrodesulfurization --- catalytic oxidation desulfurization technology is quickly grown in recent years, selection mild with oxidizing condition
Property high, green the advantages that, and oxidation product can be common to aoxidize by the simple method removing such as extraction, distillation, absorption
Desulphurization catalyst includes heterogeneous and homogeneous catalyst, and homogeneous catalyst includes heteropoly acid and heteropolyacid salt, formic acid/H2O2System
With acetic acid/H2O2System etc.；Heterogeneous catalysis includes molecular sieve catalyst, metal oxide catalyst, heteropoly acid and heteropoly acid
Salt supported catalyst etc..Most of method for preparing catalyst are complicated, commonly use active component（V、Mo、W）Higher price, cause to urge
The cost of agent is higher.Cu is prepared frequently with infusion process, is used as hydrogenation catalyst as base metal.
Invention content
The purpose of the present invention is to provide a kind of composite catalyst SiO2The preparation method of -0.1CuO.
The present invention is realized by following technical solution：
A kind of composite catalyst SiO2The preparation method of -0.1CuO, includes the following steps：20-30 parts of copper nitrates are dissolved in 55-65
In part distilled water；15-25 parts of ethyl orthosilicates, 15-25 parts of absolute ethyl alcohols and 7-9 parts of concentrated nitric acids are uniformly mixed, are added dropwise dropwise
Above-mentioned solution, is stirred continuously, until forming colloidal sol, 25-35 DEG C stands 7-9h, 45-55 DEG C of dry 25-27h, in 485-495 DEG C
Lower roasting 4-5h, cooling to obtain the final product；Each raw material is parts by weight.
Preferably, in the preparation method, 30 DEG C of standing 8h.
Preferably, in the preparation method, 50 DEG C of dry 26h.
