IMPROVED FISCHER-TROPSCH SYNTHESIS PROCESS THROUGH CONTROL OF THE PARTIAL PRESSURE OF WATER IN THE REACTION ZONE

摘要

The subject of the invention is a process for the synthesis of hydrocarbons from a feedstock of the synthesis gas type in which said synthesis gas is brought into contact with a catalyst in a reactor under Fischer-Tropsch synthesis conditions and in which the partial pressure of water is controlled to keep it below a critical value ppH2O limit defined by the formula: ppH2O limit = exp (-7751 / d pT) .P s (T) where T is the reaction temperature in K, dp is the average pore diameter of the catalyst in nm, determined by nitrogen adsorption-desorption (BJH method), P s (T) is the saturation vapor pressure of water at temperature T, in bar .
