ABSTRACT: 

 Cobalt, iron and nickel catalysts find wide application in the fuels and chemical industries, particularly in hydrogenation and hydrotreating reactions. Most commercial catalysts containing these metals consist of a metal or metal oxide phase dispersed throughout a high surface area ceramic carrier or support. Effects of surface structure, dispersion and support on activity and selectivity of the active catalytic phase were assumed until recent times to be of secondary importance. However, in the past decade there was evidence that surface structure/dispersion and metal-support interactions can dramatically influence the adsorption and activity/selectivity properties of the metals in a number of reactions. While it is desirable to study separately the effects of surface structure, dispersion and metal-support interactions, these effects are often interrelated. During the past three years, the BYU Catalysis Laboratory has been involved in an investigation of the interaction of cobalt (and to a lesser extent iron) metal(s) with alumina, silica, titania, and carbon. Results of this investigation over these past three years are summarized in this brief report. 22 refs. (ERA citation 13:003822)
