Iron antimony oxide has been known to be an active and selective catalyst for the partial oxidation of propene to acrolein and the oxidative dehydrogenation of 1-butene to 1,3- butadiene. It has become the preferred catalyst for the industrial acrolein formation from propene. The main purpose of this work was to investigate the influence of catalyst parameters such as calcination temperature, Sb:Fe ratio, type of pre-treatment, absence or presence of gaseous oxygen on the activity and selectivity in the partial oxidation of propene. Furthermore the influence of the reaction parameters temperature, space time, partial pressure, time on stream and the carbon chain length of the olefin have been studied in partial oxidation reactions using a fixed bed U-tube glass reactor. Various models have been tested for the rate of formation of products in the range of C₂ to C₆ α-olefins. Increasing the calcination temperature from 500°C to 900°C resulted in an increase of the crystallite diameter and a simultaneous decrease of the surface area which might be ascribed to high temperature sintering of the catalyst. The activity decreased proportional to the decrease of surface area. At the same time the selectivity to acrolein increased with increasing calcination temperature. 2016-11-07T17:52:49Z 2016-11-07T17:52:49Z 1997 Doctoral Thesis Doctoral PhD http://hdl.handle.net/11427/22449 eng application/pdf Centre for Catalysis Research Faculty of Engineering and the Built Environment University of Cape Town |
