ABSTRACT:

The investigations were aimed at developing novel catalysts for production of olefins with high selectivities and at finding reactor types most suitable for this synthesis. The first volume describes attempts to produce high olefin yields. With modified Mn/Fe-catalysts, a Csub(2/4)-olefin selectivity of 48% of carbon fed and a Csub(2/4) olefin yield of 77 g/m exp 3 syngas can be obtained. Product composition can be varied in a large range by zeolite addition and, therefore, can be fitted to the demands of market. In the second volume, it is shown that novel matrix catalysts produce with high selectivity linear alpha-olefins with medium-range chain length. The product mixture is composed of 93% unbranched hydrocarbons with an olefin content of 78%. Double bounds are located in 97% in alpha position. The third volume describes studies on liquid phase reactors suited for selective olefin synthesis, considering the great importance of isothermal reaction conditions. Most suitable is the slurry phase bubble column. (ERA citation 10:012625)
