  properties of Pt-Ir/Al2O3 and Pt-Ir/TiO2 catalysts for selective ring opening of naphthenes was studied. It was found that these catalysts display a strong Pt–Ir interaction but only a weak metal–support interaction. Catalyst acidities depend on the metal loading, but opposite effects were observed on alumina (decrease) or titania (increase) as the metal loading increased. The results obtained from test

  研究了铱含量对环烷烃选择性开环的Pt-Ir / Al 2 O 3和Pt-Ir / TiO 2催化剂性能的影响。发现这些催化剂显示出强的Pt-Ir相互作用，但仅表现出弱的金属-载体相互作用。催化剂的酸度取决于金属负载量，但随着金属负载量的增加，氧化铝（减少）或二氧化钛（增加）的效果相反。从测试反应（环己烷脱氢和环戊烷氢解）获得的结果表明，二氧化钛负载的催化剂的活性低于氧化铝负载的催化剂。此行为可能是由于迁移的TiO x对金属部位的部分阻塞还原步骤中的金属物种和金属相的烧结。发现甲基环戊烷开环反应是通过部分选择性机理发生的，并且观察到随着Ir负载增加活性的增加。较高的金属总量可能有利于选择性机理，这可能是由于金属聚集体尺寸的增加所致。氧化铝负载的催化剂具有较高的开环选择性。十氢化萘开环活性随金属负载量和反应温度的升高而增加。

  i.e. with KNH2 in liquid ammonia, is employed, cyclodeca-l,5- and -1,6-dienes are formed almost exclusively, as shown by their hydrogenation to cyclodecane. When heated above 70° cyclodeca-l,5-diene (2) undergoes valency isomerisation to 1,2-divinylcyclohexane (4). This compound is obtained directly in ca. 45% yield besides 46% of non-isomerisable cyclodeca-l,5- and -1,6-dienes when the HOFMANN elimination

• High-performance ring-opening catalysts based on iridium-containing zeolite Beta in the hydroconversion of decalin
  作者：Dominic Santi、Tobias Holl、Vincenzo Calemma、Jens Weitkamp

  DOI：10.1016/j.apcata.2013.01.020

  日期：2013.3

  Decalin was converted in a flow-type reactor under a hydrogen pressure of 5.2 MPa on Ir/H,A-Beta zeolite catalysts, where A stands for an alkali metal cation. In one series of catalysts, the Ir content was 3 wt.%, and the nature of A was varied from lithium to cesium. In a second series, the iridium content in Ir/H,Cs-Beta was varied from 1 to 5 wt.%. On some of these catalysts, open-chain decanes (OCDs) were formed with unprecedented selectivities and yields of up to 47 and 44%, respectively. The term "High-Performance Ring-Opening Catalysts" (HIPEROCs) was defined. Evidence is presented for hydrogenolysis on the metal being the main ring-opening mechanism on HIPEROCs. The main function of the Bronsted-acid sites is a mild isomerization of six-membered into five-membered naphthenic rings which are much easier to open by hydrogenolysis. Valuable mechanistic information can be deduced from the carbon-number distributions and the naphthenes vs. alkanes content of the hydrocracked products (C-9-). (c) 2013 Elsevier B.V.
