The open-pored ceramic column is a new product developed on the basis of the open-pored ceramic ball. It uses the diameter of the cylinder as the axis to make holes. It not only has certain mechanical strength, chemical stability and thermal stability, but also increases the specific surface area. And the void ratio, thereby increasing the dispersion and flux of the material, and reducing the resistance of the system. It can be widely used in petroleum, chemical and natural gas industries to replace inert alumina ceramic balls as catalyst covering support fillers.
Since the product was put on the market, it has been favored and praised by users. It has been proved by users that in the same reactor and reactor under the same operating conditions, compared with the original covering support material, the vapor-liquid distribution is more uniform, the flow rate is significantly increased, the system resistance is significantly reduced, and the catalyst does not agglomerate. Does not burn, thus prolonging the service life of the catalyst. The open-pored porcelain column is an updated product of the inert alumina porcelain ball.
The bulk density is small, compared with the ceramic ball, it can save more than 30% of the filling weight, which reduces the cost for support.
The pressure drop of the bed layer is small, which reduces the energy consumption of the conveying logistics machine pump.
Good uniform flow performance, which can uniformly improve the temperature and pressure distribution gradient of the catalyst bed in the reactor.
It can hold broken catalyst dust, rust, coke powder, colloid, etc., which can extend the start-up cycle.
Scope of application
This product is suitable for petrochemical, light industry, metallurgy, and environmental protection enterprise reactor catalyst cushion and capping layer packing, especially suitable for hydrogenation, reforming pre-hydrogenation, semi-regenerative reforming, catalytic cracking, Fixed bed reactors in the processing of light hydrocarbons and fixed bed reactors in the synthesis of ammonia from ethylbenzene, styrene and chemical fiber in chemical engineering.
Product manufacturing characteristics
Improving the mud making process and equipment can reduce the iron content of the product, generally up to <1%.
The molding equipment and processing process are improved, the manufacturing precision is high, the product is smooth, and the appearance and geometric dimensions are highly accurate.
The sintering furnace equipment is updated, and the sintering temperature control technology under the updated temperature is realized, which makes the product stronger. See the data in the table (measured):
