In the Fischer-Tropsch process, the applied H2/CO ratio is generally similar to the reaction stoichiometric value of 2. CO and H2 partial pressures are known to strongly influence the activity and the selectivity, especially at relatively low pressures. A detailed reaction scheme is proposed containing both primary and secondary reactions, based on measured intrinsic kinetics as function of both pCO and pH2. At the low pressures applied, added 1-hexene is prone to hydrogenation and double bond isomerization at exactly the same pace as the indigenous product, without re-initiation even in the presence of water. Added cis-2-hexene appeared unreactive as its re-adsorption is strongly hampered by steric hindrance
