一种异构化催化剂及其制备
摘要：
一种以纳米HBeta沸石为载体的正构烷烃加氢异构化催化剂。其中的纳米HBeta晶粒大小为30.0nm－180.0nm。本发明催化剂可以缩短正碳离子中间体在催化剂孔道内的停留时间，提高了异构化产物的选择性，同时抑制了聚合结焦等二次反应。本发明催化剂采用了先载金属后水热处理的制备方法，该方法降低了金属氧化物负载沸石催化剂上的较强L酸中心数，抑制了较强L酸主导的氢转移反应等副反应，降低催化剂上的积炭量。
摘要（英）：

The present invention relates to a normal paraffin hydrocarbon hydrogenation isomerization catalyst using nano HBeta zeolite as carrier, and the grain size of nano HBeta is 30.0nm-180.0 nm. Said invented catalyst can shorten the dwell time of n-carbonionic intermediate in catalyst channel, raise selectivity of isomerization product and at the same time can inhibit the secondary reaction of polymeric coking, etc. Said invention also provides the preparation method of said catalyst.
