Numerous experimental studies have persuasively shown the advantages of hydrocarbon fuel productions from synthesis gas via the Fisher-Tropsch synthesis (FTS) in slurry reactors [1,2]. The key advantages are: the effective temperature control and, as a result, almost temperature gradientless operation that permits to achieve high selectivity of C3+ hydrocarbons formation, a possibility to operate at low H2/CO ratios without catalyst deactivation, lower operation expenses compare to tubular or fluidized bed catalyst reactors etc. To design large scale slurry reactor it is necessary to have reliable reactor model and knowledge about influence of various design and operation options on FTS.
The pioneering studies of the homogeneous hydrodynamic regimes in the slurry reactors were carried out in [3,4]. By contrast, we focus on the FTS that is carried out under heterogeneous hydrodynamic regime. This regime is of interest to FTS slurry reactors because it provides a rather weak dependence from hydrodynamic parameters of linear gas flow
velocity. This is a rather important feature so far as in the course of synthesis the gas velocity is decreased along the reactor length by a factor of 2, therefore the hydrodynamic regime is also changed.
