In the kinetic models of higher alcohol synthesis developed in this study, the reaction products were treated on a lumped basis. The alcohols and hydrocarbons (unbranched alkanes) are regarded as single pseudocomponents with average carbon number chain length depending on the process variables. The lumped treatment of the kinetics seems to be valuable to get better understanding of the effect of operating variables. The advantage of such type of models is a reduced number of parameters to be estimated. Three types of the rate equations describing the formation rates of alcohols, hydrocarbons and the rate of water-gas-shift reaction were assumed. The discrimination between the proposed rate equations was based on experimental rates measured in a tank slurry reactor over a modified Cu/ZnO catalyst. The inhibiting effect of water vapour appeared to be the most important for production of alcohols and hydrocarbons.
