A study of nickel microwires as catalysts in the liquid phase hydrogenation of alkenes

Abstract

Recent advances in metal fiber production have resulted in the capability of large scale production of very small diameter filaments of nickel called nickel microwircs. These nickel microwires were studied as potential new catalysts for use in hydrogenation reactions. The studies were carried out by the hydrogenation of 1-octene al various reaction conditions. This study shows that 2µm diameter nickel microwires exhibit very high activity and a long life time as compared to other commonly used industrial nickel catalysts. This tudy also shows that the activity of the nickel microwires is affected by the diameter of the wire. the method by which the microwirc is manufactured and the method of pretreatment of the microwire prior to use. Data show that a high specific surface area and an apparent high density of active sites and low activation energy are responsible for the high catalytic activity of the nickel m1crow1res. The results of this study show that nickel microwires are easy to use in heterogeneous stirred tank reactors and possess the potential for being very useful industrial hydrogenation catalysts.
