The main products are honeycomb ceramics regenerative filler, activated carbon, activated alumina, molecular sieve, porcelain ball, tower packing and catalyst for dozens of products, packing honeycomb ceramic heat storage heat capacity J/kgk1000 above, temperature ?ݠ1700 ?欠the furnace, baking, soaking furnace, kiln cracking furnace and other fuel savings of up to 40%, and production increased by 15%, and flue gas temperature below 150 ?殠Activated carbon powder or granules made of honeycomb shape, greatly improving the water purification and wastewater treatment capacity, especially in the pharmaceutical industry in antibiotics, hormones, vitamins, nuacleic acids and various injections injections, drugs dehydration bleaching to impurities. Honeycomb ceramic filler filler than any other shape than the surface area of ​​greater strength and better, etc., allows more uniform distribution of gas-liquid, the bed resistance is reduced, better, and extended service life, in the petrochemical, pharmaceutical and fine chemical industry as a filler effect is quite good. Honeycomb ceramic catalyst for use in a better position. The honeycomb ceramic as the carrier, using a unique coating materials, precious metals, rare earth and transition metal preparation, which has high catalytic activity, good thermal stability, long life, high strength and so on. Catalytic cracking of ceramic honeycomb is used to replace existing products. FCC use 200 ~ 500 ?栢etween heavy distillates as the raw material (including vacuum distillate, light straight-run diesel, coker gas oil, etc.) to aluminosilicate as a catalyst, the reaction temperature between 450 ~ 550 ?栨 varies with the type of reactor). It yields large (each of the major catalytic cracking unit, cracking of oil over one million tons per year), technical conditions require high (for example, the catalyst contacts the oil every few minutes or even seconds will regenerate every minute of flow through the catalyst bed 10t or more) with increased catalytic activity, in order to speed up the rate of regeneration, the regeneration conditions are more demanding. For example, 600 ~ 650 ?欠or 700 ?欠catalyst consumed in large quantities, oil consumption per ton of feed 0.3 ~ 0.6kg catalyst, a catalyst with poor mechanical strength, much larger consumption. This requires a catalyst activity, selectivity, stability is slightly improved, actual production will be of great significance. Because of this, ceramic honeycomb catalyst also continues to introduce new, market demand is also growing, the catalytic cracking catalyst used in ceramic honeycomb catalyst was replaced by large number of porous ceramic honeycomb catalyst has emerged, with strong momentum.
