NKC-5（芳构化）催化剂
NKC-5（C5 Aromatization）Catalyst
1、催化剂适应原料广泛，用于C3、C4气体，直馏汽油，凝析油的芳构化反应。
2、用于将碳五馏分转变为苯（B）、甲苯（T）、二甲苯（X），并副产乙烯、丙烯、乙烷、丙烷等有价值产品的催化剂。
适用原料：乙烯工程的副产品C3~C7
特点：反应转化率高，芳烃收率高，抗结焦能力强，尤其适用于高烯烃含量的C5原料，允许原料中烯烃含量达80%。经使用证明该催化剂在轻烃（C3~C7)芳构化及生产高辛烷值汽油的反应中也具有优良的催化性能。
The NKC-5 Catalyst For C5 Aromatization
The NKC-5 Catalyst for C5 to aromatics is based on a synthetic zeolite. The catelyst can convert alkane or alkene of C5 to aromatics mainly containing benzene(B), toluene(T) and xylenes(X), accompanied by the production of hydrogen and C1-C4 organic gases.By coinversion of C5 hydrocarbon,the valuble aromatics, ethene,propene and liquefied petroleum gas can be obtained. So the application of this catalyst is extremely profitable.
The NKC-5 Catalyst has become commercial,and has been used for about 3 year by the Danhua Group Co.,Jiangsu Proviince with an annual treatment of 30.000 tons C5. The concersion of C5 is more than 95%,and the yield of aromatics ranges from 60% to 70%.C3,C4 account for 50% of the organic gases produced,and ethene,propene for about 20%.
The NKC-5 Catalyst,with its remarkable stability and resistance to coking,could tolerate the feedstock containing 80% alkene of C5 .
