Abstract
Mono- and di-olefins are prepared by catalytic oxidative dehydrogenation of paraffins with O2 diluted with steam, N2, A and/or He, in the presence of oxides of Mo and/or W and at least one oxide of Cr, Mn, Fe, Ni or Cd on a carrier such as silica gel, alumina or an aluminosilicate, or their mixtures, at 400-700 C. The process is continuous and gives good yields of olefines without the need of regenerating the catalyst periodically. The products are valuable intermediates, especially for synthetic rubbers.
