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 a preparation method and application thereof, in particular to a multi-active component carbon monoxide adsorbent and a preparation method and application thereof. Background technique [0002] At present, the carbon monoxide removal agents involved in related patent documents are divided into two categories: the first category is catalytic reaction type such as Pd / Al 2 O 3 The removal mechanism is that the precious metal Pd is used as a catalyst, and the oxygen contained in the raw material is used or the carbon monoxide in the raw material is reacted to generate carbon dioxide to achieve the removal purpose. However, this type of carbon monoxide removal agent has the following problems: 1. Because the catalyst itself contains the precious metal Pd, in the process of removing carbon monoxide from the hyd...
