XI-1 xylene isomerization catalyst
XI-1 xylene isomerization catalyst is mainly used in the conversionfrom the C8 aromatics nonbalance mixture into balance components, from ethylbenzeneinto xylene. For different compositions of feed stock (for example: C8 aromatic hydrocarbons containing high ethyl benzene content ) and the requirements of different purposed products, the catalyst has good adaptability.If the feed stock changes, just adjust process conditions appropriately, it can produce p-xylene or o-xylene and p-xylene.The catalyst is a bi-function platinum-containing catalyst, taking high-purity alumina and special zeolite as carrier, with outstanding activity, selectivity and stability. The catalyst possesses the characteristics of high activity, stability and selectivity. In the reaction process, it is not necessary to fill the chlorine, no corrosion to equipment, which makes operation simpler, meanwhile, avoids the environmental problem and other losses, which improves comprehensive economic benefits significantly
