Claims (5)

1. Способ оптимизации производства тяжелых углеводородов по способу Фишера-Тропша и относящегося к нему выделения вышеупомянутых углеводородов, исходя из смеси газов-реагентов, состоящей по существу из СО и Н2, возможно разбавленной СО2, в присутствии катализаторов на носителях, который включает:
(а) подачу газов-реагентов в реактор, предпочтительно со дна, так, чтобы получить хорошее распределение твердого вещества в жидкой фазе, таким образом осуществляя по меньшей мере частичное преобразование газов-реагентов в тяжелые углеводороды, причем скорости течения газа таковы, чтобы работа происходила при гетерогенных условиях или условиях турбулентно перемешиваемого потока;
(б) по меньшей мере частичный отбор тяжелых углеводородов, образованных на стадии (а), путем их отделения вне или внутри аппарата от частиц катализатора;

A method for optimizing the production of heavy hydrocarbons according to the Fischer-Tropsch method and the associated emission of the above hydrocarbons, starting from a mixture of reactant gases consisting essentially of CO and H 2 , possibly diluted with CO 2 , in the presence of supported catalysts, which includes
(a) supplying the reactant gases to the reactor, preferably from the bottom, so as to obtain a good solid distribution in the liquid phase, thus at least partially converting the reactant gases into heavy hydrocarbons, and the flow rates of the gas are such that work takes place under heterogeneous or turbulent flow conditions;
(b) at least partially withdrawing the heavy hydrocarbons formed in step (a) by separating them outside or inside the apparatus from the catalyst particles;
moreover, the above method differs in that in stage (a) the reaction occurs:
(1) in the presence of solid particles, so that the Reynolds number for particles (Re p ) is greater than 0.1, where
