Abstract:
The present invention relates to a continuous separation and discharge apparatus and method of solid catalysts and liquid products for Fischer-Tropsch synthesis reactions, and more particularly, to a continuous separation and discharge apparatus and method of solid catalysts and products for Fischer-Tropsch synthesis reactions involving the conversion of synthetic gas into synthetic oil, by which products of the Fischer-Tropsch synthesis including wax, as a long-chain hydrocarbon, can be stably obtained by continuously separating the products from a slurry comprising solid catalyst particles and the products using periodic pulses of a feeding gas and discharging the products through a lower portion of a reactor. Provided is a continuous separation and discharge apparatus of solid catalysts and products for Fischer-Tropsch synthesis reactions including: a level sensing device which is installed at an upper portion of a reactor and detects the slurry-level of reactants; a solid catalyst/ product separation device and a discharge device which are installed at a lower portion of the reactor and separate and discharge liquid products from a mixed slurry in the reactor; and a control unit which receives a signal from the level sensing device to open and close the discharge device, wherein the separation device filters the solid catalysts, and the discharge device continuously discharges the products separated from the solid catalysts through the lower portion of the reactor by the amount of the synthesized products measured by a level sensing device.
Abstract:
The invention discloses an apparatus and process for the reformation of hydrogen containing fluids in a cyclic flow inert porous media reactor. The hydrogen containing fluid can be hydrogen sulfide. The cyclic flow reactor comprises a reaction chamber filled with a porous media matrix containing an unconstrained reaction zone located in any portion of the reactor chamber. This reactor system employs valves to canalize the reactant mixture and product mixture during flow cycling channeling the reactant mixture through the porous media matrix, and reacting the reactant mixture. In another embodiment, the reactor system may further comprise at least one aperture along the axial length of the reactor casing to enable mounting of an external energy source and /or at least one heat exchanger to' provide a source of heat transfer to the inlet pipe and outlet pipe as well as the reactant mixture and product mixtures.
Abstract:
There is provided a bubble column type hydrocarbon synthesis reactor which synthesizes a hydrocarbon compound by a chemical reaction of a synthesis gas including hydrogen and carbon monoxide as main components, and a slurry having solid catalyst particles suspended in liquid. The hydrocarbon synthesis reactor includes a reactor main body which accommodates the slurry, a synthesis gas supplying section which supplies the synthesis gas to the slurry; one pressure sensor which is arranged higher than the liquid level of the slurry to measure the pressure of the synthesis gas above the liquid level, another pressure sensor which is arranged lower than the liquid level of the slurry to measure the pressure of the slurry, and a liquid level detecting device which detects a liquid level position of the slurry on the basis of measurement results of the pressure sensors. A plurality of the other pressure sensors are provided at arbitrary intervals in an axial direction of the reactor main body.
Abstract:
Dies Verfahren dient zum Entfernen von feinteiligem Silizium-Material, insbesondere mit Korngrößen kleiner als 1 µm, aus einem Silizium-Mahlgut (Si) mit Korngrößen kleiner als 500 µm. Das in einem Reaktionsbehälter (22) befindliche Silizium-Mahlgut (Si) wird mit einer wässrigen oder wasserenthaltenden Lösung einer Base (NaOH, KOH) aus einem Vorratsbehälter (26, 28) unter Rühren versetzt. Es erfolgen dabei eine Suspendierung und ein Aufschäumen. Hierbei findet ein Ätzprozess statt, bei dem die feine Fraktion mit Korngrößen kleiner als 1 µm chemisch entfernt wird. Diese Fraktion geht in Lösung. Nach einer gewünschten Zeit, nämlich sobald die feine Fraktion praktisch vollständig in Lösung gegangen ist, wird der Ätzprozess abgebrochen. Dies kann durch Zugabe einer Säure (HCl) aus einem weiteren Vorratsbehälter (30) geschehen. Alternativ kann dies auch durch Zugabe von viel Wasser aus einem zusätzlichen Vorratsbehälter (28) bewirkt werden. Der Zeitpunkt für das Abbrechen wird z. B. an einem Zeitgeber (86) eingestellt oder aber während des Ätzprozesses mit einem Messgerät (88, 90) ermittelt. Das zurückgebliebene grobkörnige Festgut (10) kann nun nach Sedimentierung für die weitere Verwendung oder Bearbeitung bereitgestellt werden.
