Abstract

The reaction of carbon monoxide decomposition has been a subject of interest for many years. The main factors which affect on the CO disproportionation speed and on the properties of produced solid products are temperature, catalyst nature, gas phase composition. One of the aims of this research is to study the influence of the catalyst nature on the carbon deposit fine structure. The experiments were conducted at the flowing experimental set. Finegrained cobalt oxide (Co3O4) and cotton were used as a solid material in the present investigation of the rate of CO disproportionation in the presence of H2O. Cotton was saturated with salts solutions of the metal-catalysts (Fe, Co, Ni). It was found that small additions of H2O markedly enhance the rate of carbon deposition and that there is an optimum content of H2O in CO-H2O mixtures which provides the maximum rate of carbon deposition. The study of carbon structure was carried out at UHR SEM of Center for Nanoscience and Nanotechnology, Jerusalem, Israel. During the СО disproportionation on the surface of cobalt catalyst the carbon is crystallized in the form of globules (balls) and in the form of fibers (nanotubes).
