Influence of the nature of the texture promoter on the catalytic properties of nickel-copper catalyst for hydrocarbons processing obtaining carbon nanofibers

Abstract

The results of research into the development and optimization of the preparation method of the catalyst to be processed a hydrocarbons to carbon materials are presented in this article. The mechanochemical activation of metal oxides mixture in a planetary mill was chosen as the method of preparing the catalyst. This method allows to obtain in a single stage high-proof (the active component, 90–95 wt.%) oxide catalyst without the formation of harmful waste gases during calcination. For stabilization of such catalysts they are used a textural promoter which prevents caking of dispersed metal particles at high temperature of carbon materials synthesis. The paper contains a texture promoter selection and optimization of the preparation conditions of the oxide precursor nickel-copper catalyst.
