Preparation method of honeycomb ceramic carrier capable of improving catalytic efficiency of catalyst
The invention discloses a honeycomb ceramic carrier preparation method capable of improving the catalytic efficiency of a catalyst. The honeycomb ceramic carrier preparation method comprises the following steps: S1, raw material preparation and pretreatment; S2, raw material and additive mixing; S3, honeycomb ceramic carrier blank manufacturing; according to the preparation method of the honeycomb ceramic carrier capable of improving the catalytic efficiency of the catalyst, raw materials are pretreated and then mixed with the catalyst, a green body is processed through an extruder after mixing is completed, the green body is dried, trimmed and then fed into a heating furnace to be fired, and after firing of the honeycomb ceramic catalyst carrier is completed, the honeycomb ceramic catalyst carrier is obtained. The surface of the honeycomb ceramic catalyst carrier is subjected to acid washing and alkali washing, the surface of the carrier is roughened, so that three-dimensional through holes of the carrier are communicated, the specific surface area and the pore structure of the carrier are improved, the activity of the catalyst is enhanced, and the catalytic reaction time and efficiency can be greatly improved through the process.
