Abstract
A process for synthesising hydrocarbons by reacting a mixture comprising at least carbon monoxide and hydrogen in the presence of a catalyst is carried out in a three-phase reactor in which the liquid Peclet number is in the range 0 (excluded) to about 10, with a superficial gas velocity U that is preferably less than 35 cm.s , to encourage gas transfer into the liquid phase and avoid too much attrition of the catalyst grains.
