Abstract:

Method, apparatus and system for controllably conveying magnetic particles between closed chambers. Magnetic particles are magnetically attracted from a first solution-containing chamber into a motive cavity, such as may be formed in a rotor of a pump. The magnetic particle-containing motive cavity is then moved out of fluid communication with the first solution-filled chamber and moved into fluid communication with a second solution-filled chamber. Finally, the magnetic particles are magnetically releasing from the motive cavity into the second solution-containing chamber. The first and second chambers are preferably never in direct fluid communication. Because the rotor is sealed with the pump body and there is no direct fluid communication between the first and second chamber, contact between the first solution and the second solution is limited by the size of the motive cavity. Optionally, the particles are magnetically attracted by temporarily inserting a magnet into a rotor. This method has significant advantages over existing magnetic particle manipulation systems because it can be utilized as a closed system with a very innovative and low-cost approach.

Abstract:

Hydrogen gas production includes supplying a hydrocarbon fluid to a gap between a pair of electrodes, applying a voltage across the electrodes to induce an electrical arc, wherein the electrical arc contacts the hydrocarbon to form a plasma and produces a gaseous product comprising hydrogen gas and a solid product comprising carbon, and dynamically adjusting the gap length to control at least one parameter of the plasma. Preferably, the gap length is decreased during plasma initiation or reformation and increased to increase the hydrogen gas production rate. The method preferably includes dynamically adjusting the spatial separation of the electrodes and rotating at least one electrode while generating hydrogen gas to reduce adherence of solids to the electrodes. Furthermore, the polarity of the electrodes may be periodically reversed, primarily to reduce adherence of solids. If the hydrocarbon fluid is a liquid, the method may include controlling the level of the hydrocarbon liquid relative to the pair of electrodes.
