ABSTRACT:

The work supports the assumption that chain lengthening reactions are rapid and also shows that the hydrogenation of olefins to form paraffins can be minimized by control of the hydrogen pressure. A metallocylcobutane intermediate in the Fischer-Tropsch reaction appears to be plausible. It was found that olefins homologate on iron catalysts in competition with hydrogenation. Since the homologation reaction occurs to an enhanced extent at lower contact times, it appears to be a fast reaction compared with hydrogenation and may share common intermediates with the Fischer-Tropsch synthesis.
