Problems solved by technology

The solid catalyst material used in the gas-solid contact reaction is usually filled in granular form or loaded on a carrier with a high specific surface area. During use, the filled granular catalyst material usually has a relatively large wind resistance, which affects the smooth progress of the reaction. ; and the powder materials loaded on the carrier with high specific surface area are often easy to fall off, which brings a lot of inconvenience

Description

technical field [0001] The invention relates to a catalyst material and a molding method thereof, in particular to a honeycomb catalyst material and an extrusion molding method thereof. Background technique [0002] With the advancement of human manufacturing and production technology, the discharge of pollutants has also increased with the surge in total production. These pollutants containing harmful gases stay in the atmosphere and cause serious pollution to the environment on which human beings depend. It even endangers human health. [0003] At present, harmful gases are mainly removed by gas-solid or gas-liquid contact reaction. For this contact reaction, the larger the contact area, the higher the reaction efficiency and the better the air purification effect. Since a variety of catalyst materials and a variety of harmful gas components in the air can undergo catalytic decomposition reactions, these harmful substances can be removed to purify the air. In the process...
