Cobalt-Iron-Manganese Catalysts for the Conversion of End-of-Life-Tire-Derived Syngas into Light Terminal Olefins.

This corresponds to a marked reduction in the hydrocarbon yields (Table 4 ) for the CH 4 and the C 5+ fractions, whereas the C 4 olefin productivity is maintained at 0.03 kg⋅kg cat −1 ⋅h −1 . For the distribution of individual compounds within the C 4 fraction, there is a clear trend that the amount of formed terminal olefins increases with an increasing Na/S ratio, whereas a lower ratio leads to higher amounts of internal olefins (Figure 2 ).
