The shape of honeycomb ceramic catalyst protector is square or cylindrical, and the inner cavity of the product has uniform size through holes which are parallel or staggered from top to bottom and staggered or parallel from left to right (the inner cavity of honeycomb proppant also has closely ordered through holes which are uniform in size and thin in wall), so its specific surface area is more than 800m2 / m3, The porosity can reach 60-90%, which can not only effectively support the catalyst and increase the service life of the fixed bed reactor, but also help to realize impurity filtration, adsorption, gas-solid reaction, adsorb a large number of catalyst particles, increase the contact area of the catalyst, improve the catalytic activity, improve the catalytic effect and reduce the operation cost. Honeycomb ceramic catalyst carrier is widely used as support carrier and protection system of catalysts for continuous reforming, hydrogen production, hydrogenation and hydrofining in oil refining, petrochemical, chemical, environmental protection and metallurgy industries.
