Forsterite honeycomb body as well as preparation method and application thereof

Abstract

The invention provides a forsterite honeycomb body. The forsterite honeycomb body comprises the following main and auxiliary materials: 90-92 wt% of forsterite fine powder, 5-9 wt% of an adsorbent and 1-3 wt% of grease; and the auxiliary ingredients comprise 1.5-3.5 wt% of a binding agent A and 1-2.5 wt% of an additive B, wherein the binding agent A accounts for 1.5-3.5 wt% of the main ingredient. The invention further provides a preparation method of the forsterite honeycomb body. The preparation method comprises the steps of material mixing, forming, drying and heat treatment. The invention further provides application of the forsterite honeycomb body. The forsterite honeycomb body is used for neutralizing and absorbing carbon dioxide. According to the invention, after the absorbent is mixed with magnesium oxide of forsterite, carbon dioxide is rapidly absorbed by the absorbent, and then the magnesium oxide and the carbon dioxide are chemically cured, so that the absorption speed is greatly increased on the premise of ensuring the absorption rate; the preparation method used in the invention is simple in process and low in raw material cost, and the prepared forsterite honeycomb body has the advantages of large reaction area and good air permeability, and is beneficial to large-scale industrial production influence.

Description

technical field [0001] The invention relates to the technical field of carbon dioxide neutralization, in particular to a forsterite honeycomb body, a preparation method and an application thereof. Background technique [0002] At present, reducing the adverse impact of carbon dioxide CO2 on the environment is an important task in the field of environmental protection technology. [0003] Existing carbon neutral technologies widely use chemical absorption to capture CO2 and then process it. There are many treatment techniques, such as pressing CO2 into the ground and storing it in the formation, or converting CO2 and co-reactants into target products, so as to achieve resource utilization of CO2 and achieve carbon neutrality, etc. Among them, the use of mineral raw materials as reactants to chemically react with CO2 to generate new solid substances to solidify CO2 and achieve carbon neutrality is a very good carbon neutralization technology. This method does not need to dis...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies in the prior art, the present invention provides a forsterite honeycomb body, a preparation method and its application, which solves the problem in the prior art that the reaction rate is relatively slow, so carbon dioxide needs to be recycled multiple times to A better absorption effect is achieved, which reduces the production efficiency; and the surface area of ​​the solid material is not large enough, resulting in a small contact area between the material and CO2, resulting in a low reaction rate
