使用金属催化剂对二甲基萘进行脱氢处理

Dehydrogenation process of dimethylnaphthalene using metal catalyst
Abstract:
Disclosed herein is a process of producing high purity and high yield dimethylnaphthalene by dehydrogenating a dimethyltetralin isomer using a metal catalyst for dehydrogenation. The metal catalyst contains a carrier selected from alumina (Al2O3), silica (SiO2), a silica-alumina mixture and zeolite. The metal catalyst also contains 0.05 to 2.5% by weight of platinum (Pt), 0.1 to 3.0% by weight of tin (Sn) or indium (In), 0.5 to 15.0% by weight of at least one selected from the group consisting of potassium (K), magnesium (Mg) and cesium (Cs), 0.3 to 3.0% by weight of chlorine, and 0.01 to 3.0 % by weight of zinc (Zn) or gallium (Ga) as active components based on an element weight of the final catalyst.
Abstract(Chinese):

本文公开了通过使用用于脱氢的金属催化剂使二甲基四氢萘异构体脱氢来生产高纯度和高收率的二甲基萘的方法。 金属催化剂含有选自氧化铝（Al 2 O 3），二氧化硅（SiO 2），二氧化硅 - 氧化铝混合物和沸石的载体。 金属催化剂还含有0.05〜2.5重量％的铂（Pt），0.1〜3.0重量％的锡（Sn）或铟（In），0.5〜15.0重量％的选自以下的至少一种： 钾（K），镁（Mg）和铯（Cs），0.3〜3.0重量％的氯和0.01〜3.0重量％的作为活性成分的锌（Zn）或镓（Ga） 最终催化剂。
