  Oxygen-Deficient Tungsten Oxide as Versatile and Efficient Hydrogenation Catalyst

  摘要：

  Heterogeneous hydrogenation is one of the most important industrial operations, and reduced metals (mostly noble metals and a few inexpensive metals) generally serve as the catalyst to activate molecular H-2. Herein we report oxygen-deficient tungsten oxide, such as WO2.72, is a versatile and efficient catalyst for the hydrogenation of linear olefins, cyclic olefins, and aryl nitro groups, with obvious advantages compared with non-noble metal nickel catalyst from the aspect of activity and selectivity. Density functional theory calculations prove the oxygen-deficient surface activates H-2 very easily in both kinetics and thermodynamics. Testing on several oxygen-deficient tungsten oxides shows a linear dependence between the hydrogenation activity and oxygen vacancy concentration. Tungsten is earth-abundant, and WO2.72 can be synthesized in large scale using a low-cost procedure, which provides an ideal catalyst for industrial application. Because oxygen vacancy is a common characteristic of many metal oxides, the findings in this work may be extended to other metal oxides and thus provide the possibility for exploring a new type of hydrogenation catalyst.

  Process for producing ethylidenorbornene (ENB) comprising a stage of thermal cracking of DCPD to CPD carried out in an inert fluid to which it is fed a stream of DCPD comprising virgin DCPD from cracking containing up to 10% wt of tetrahydroindene (THI) and recycled DCPD containing THI coming from the subsequent stage of formation of vinylnorbornene. The contact time of DCPD with the heat transfer fluid is of few seconds and it is sufficient to achieve a conversion of said DCPD ≥ 95%, with little formation of oligomers. THI is then separated from the heat transfer fluid substantially free from DCPD and enriched in THI to a fractionation column.

  生产乙烯基环戊烯（ENB）的过程包括热裂解二环戊二烯（DCPD）为环戊二烯（CPD）的阶段，该阶段在惰性流体中进行，其中向其中提供了一流含有来自裂解的原始DCPD和含有来自后续形成乙烯基环戊烯的THI的回收DCPD的流。DCPD与传热流体的接触时间为几秒钟，足以使所述DCPD的转化率≥95％，且寡聚物形成较少。然后，从基本上不含DCPD的传热流体中分离出THI，并富集到分馏柱中。
