Embodiment 1

[0028] Weigh Cu(NO 3 ) 2 , Zn(NO 3 ) 2 , Mn(NO 3 ) 2 , Ni(NO 3 ) 2 , Fe(NO 3 ) 3 , as shown in Table 1, stir and dissolve the above-mentioned substances in hot water at 65°C, inject the mixed solution into the reactor, and configure an excess of 20% of the aging agent Na 2 CO 3 The solution was slowly injected into the same reactor for 4h aging reaction, the reaction was controlled at 70°C and the pH value was 9-10, and then the reacted slurry was centrifuged to make a filter cake, dispersed and washed (water temperature 70°C) and repeated for 2 -3 times until the pH value of the slurry is 6-7, then dry the filter cake at low temperature and roast at 600°C for 5 hours, and granulate the activated oxide powder roasted at high temperature into columnar shape Ф5×(3~7) for later use. Take 200ml of catalyst respectively and put them into a stainless steel reactor of Ф40mm×2.5mm×300mm, and pass nitrogen gas at a space velocity of 10h -1Purge for 2h. Under the conditions ...

Abstract

The invention relates to a multi-element high-activity component carbon monoxide adsorbent as well as a preparation method and application thereof. The multi-element high-activity component carbon monoxide adsorbent is mainly prepared by an active component co-precipitation method; an active component comprises high-valence oxide of Cu, Zn, Mn, Ni and Fe: CuO, ZnO, MnOx, NiO and FeOy as well as dispersing agent Al2O3 powder. The multi-element high-activity component carbon monoxide adsorbent as well as the preparation method and application thereof have the benefits that by utilizing the characteristic of complementary performances of different components, the multiple components reach high-valence states through oxidation, and further, the ability to remove carbon monoxide by chemical adsorption is realized; the effect of a catalyst of the multi-element high-activity component carbon monoxide adsorbent is superior to that of a single or two-component catalyst; the multi-element high-activity component carbon monoxide adsorbent has the advantages of being free from loss of effective component of feed gas, high in removal depth, large in capacity, low in activation temperature, strong in anti-sintering ability, long in service life, high in mechanical strength, hard to pulverize and the like, is suitable for C2H4, C3H6, CH4, H2, N2, He, Ne, Ar, Kr, Xe and deep removal of the carbon monoxide by electron gas, and can be widely applied to large-scale industrial production.

Description

technical field [0001] The invention relates to a carbon monoxide adsorbent used in petrochemical, electronics, metallurgy, gas, analysis, semiconductor and other industries and its preparation method and application, in particular to a carbon monoxide adsorbent with multiple active components and its preparation method and application. Background technique [0002] At present, the carbon monoxide removal agents involved in relevant patent documents are divided into two categories: the first category is catalytic reaction type such as Pd / Al 2 o 3 etc., the removal mechanism is noble metal Pd as a catalyst, using the oxygen contained in the raw material itself or by adding oxygen to react with carbon monoxide in the raw material to generate carbon dioxide to achieve the purpose of removal. However, this type of carbon monoxide removal agent has the following problems: 1. Because the catalyst itself contains the noble metal Pd, during the process of removing carbon monoxide i...
