Claims (21)
a) введение первой порции каталитических частиц в верхнюю часть реакционной зоны, содержащей движущийся слой каталитических частиц, поддерживаемый на конструкции носителя катализатора, внутри, в основном, реактора цилиндрической формы;
b) удаление второй порции каталитических частиц из нижней части указанной реакционной зоны;
c) введение жидкого сырья, включающего углеводород и водород, через конструкцию носителя катализатора в нижнюю часть указанной реакционной зоны; и
d) удаление превращенных углеводородов из верхней части указанной реакционной зоны,
где конструкция носителя катализатора включает перфорированный конический элемент носителя, расходящийся вверх и имеющий усеченную коническую форму, причем указанная форма усечена донной пластиной; по крайней мере одно верхнее направляющее поток устройство, прилегающее к указанному коническому элементу носителя, расширяющееся вверх, и имеющее высоту выше конического элемента носителя, достаточную для того, чтобы направить поток жидкости вверх в слой катализатора, причем указанное верхнее направляющее поток устройство образует непрерывную, обычно кольцевую конструкцию, концентричную донной пластине, для уменьшения миграции жидкого сырья вдоль верхней поверхности конического элемента носителя.14. The method of interaction of hydrocarbon liquid raw materials, characterized in that it includes the following stages:
a) introducing the first portion of the catalytic particles into the upper part of the reaction zone, containing a moving bed of catalytic particles supported on the structure of the catalyst carrier, inside a generally cylindrical reactor;
b) removing a second portion of the catalytic particles from the bottom of said reaction zone;
c) introducing liquid feed, including hydrocarbon and hydrogen, through the construction of the catalyst carrier into the lower part of the specified reaction zone; and
d) removing the converted hydrocarbons from the top of said reaction zone,
where the design of the catalyst carrier includes a perforated conical element of the carrier, diverging upward and having a truncated conical shape, said shape being truncated by a bottom plate; at least one upper flow guide device adjacent to said conical support element, expanding upward and having a height above the conical support element, sufficient to direct fluid flow upward into the catalyst bed, said upper flow guide device forming a continuous, usually ring design, concentric with the bottom plate, to reduce the migration of liquid raw materials along the upper surface of the conical element of the carrier.
a) перфорированный конический элемент носителя, расходящийся вверх и имеющий коническую форму, усеченную круглой донной пластиной, и в которой конический элемент носителя представляет собой конусообразную пластину, имеющую множество отверстий, распределенных по поверхности указанного конического элемента носителя, размером, достаточным для того, чтобы допустить проход восходящего потока жидкости; и
b) экранный элемент, включающий множество продольных стержневых элементов, расположенных в поперечном направлении по несущим стержневым элементам, причем указанный экранный элемент покрывает и прикреплен к указанному коническому элементу носителя при помощи по крайней мере одного непрерывного, обычно кольцевого соединения между верхней поверхностью конического элемента носителя и экраном, для уменьшения миграции жидкого сырья вдоль верхней поверхности конического элемента носителя.19. The design of the catalyst carrier to maintain a moving bed of catalytic particles inside a generally cylindrical shape of a reactor having an upward flowing liquid phase, characterized in that it includes the following elements:
a) a perforated conical carrier element, diverging upward and having a conical shape, truncated by a round bottom plate, and in which the conical carrier element is a cone-shaped plate having a plurality of openings distributed over the surface of said conical carrier element with a size sufficient to allow upward passage of fluid; and
b) a screen element comprising a plurality of longitudinal rod elements arranged transversely along the bearing rod elements, said screen element covering and attached to said conical carrier element by means of at least one continuous, usually circular connection between the upper surface of the conical carrier element and screen, to reduce the migration of liquid raw materials along the upper surface of the conical element of the carrier.
