Abstract
The present invention relates to a preparation method of a copper- based synthetic gas purifier, which belongs to the technical field of a catalyst. A Cu-Zn-Cr system is mainly adopted. A prepared purifier can effectively eliminate Fe (CO) 5 and Ni (CO) 4 in synthetic gas. Simultaneously, the prepared purifier can perform the function of eliminating S. The preparation method adopts the combination of a coprecipitation method and a mechanical mixing method. The purifier prepared by the method is suitable for the synthetic gas with CO, CO2 and H2, and is especially suitable for a carbinol synthesis device of the synthetic gas.
Description
Technical field: the invention belongs to catalyst technical field, be specifically related to a kind of preparation method of copper-bearing synthetic gas purifier.
Background technology: synthetic gas is the unstripped gas of a series of Cl chemical such as synthesizing methanol, dme, alkene, its building-up reactions catalyst system therefor often can make all to the more responsive a spot of impurity element of impurity element such as As, S, Cl, Fe, Ni etc. that the synthetic catalyst activity reduces greatly, by product increases, shorten catalyzer work-ing life, therefore, be necessary synthetic gas is purified, remove impurity elements such as As, S, Cl, Fe, Ni.The scavenging agent use that removes at present As, S, Cl element specially is more, and uses less at the scavenging agent of elements such as Fe, Ni.
Summary of the invention: the present invention is the preparation method that will propose a kind of copper-bearing synthetic gas purifier, adopts the Cu-Zn-Cr system.The scavenging agent of the present invention preparation can remove Fe, Ni in the synthetic gas effectively (in synthetic gas generally with Fe (CO)
5And Ni (CO)
4Form exists), also can play the effect of taking off S simultaneously.
The present invention adopts co-precipitation in conjunction with mechanical mixing, it mainly may further comprise the steps: concentration range is mixed at the soluble Zn salts solution that soluble copper salts solution and the concentration range of 10～250g/L is 10～250g/L, be the reaction of 5～20% precipitation agent with concentration then, the precipitation of making after filtration, oven dry is back and the compound mechanically mixing of chromium, through roasting, compression molding.
The scavenging agent of the present invention's preparation, copper zinc chrome ratio is Cu: Zn: Cr=1: (0.5～3): (0.5～3).
The used soluble copper salt of the present invention can be a nitrate; Soluble zinc salt can be a nitrate; Precipitation agent can be Na
2CO
3, also can be NaHCO
3The compound of chromium can be CrO
