The subject invention provides systems and methods for capturing carbon dioxide in a cyclic process of mechano-chemical reactions. The subject invention also provides systems and methods for synthesizing siderite, by means of mechano-chemical reactions, using mill rotation. Siderite acts as an efficient reversible sorbent and can be decomposed, generating magnetite, carbon and/or metallic iron as well as pure carbon dioxide. Said systems and methods employing carbon dioxide capture/release reactions in the carbonation-calcination cycles are suitable for using in any iron, steel and non-steel industries to reduce carbon dioxide emissions into the atmosphere.

A substance is treated using a device having: (a) a volute or cyclone head, (b) a throat connected to the volute or cyclone head, (c) a parabolic reflector connected to the throat, (d) a first wave energy source comprising a first electrode within the volute or cyclone head that extends through the outlet into the opening of the throat along the central axis, and a second electrode extending into the parabolic reflector and spaced apart and axially aligned with first electrode, and (e) a second wave energy source disposed inside the throat, embedded within the throat or disposed around the throat. The substance is directed to the inlet of the volute or cyclone head and irradiated with one or more wave energies produced by the first and second wave energy sources as the substance passes through the device.

A filtration system is described that can be used to filter out plant material within a solution. One or more sieves can be disposed in series to receive a flow of solution. As the solution flows through the one or more sieves, progressively smaller particles can be filtered out. One or more transducers can apply sound waves or other agitation during the filtering process. The sound waves help in suspending solid particles in the solution and making for more efficient and quicker filtering.

The present disclosure provides a method for separating soluble organic matter in petroleum coke, including: drying the petroleum coke to obtain pretreated petroleum coke; extracting the pretreated petroleum coke sequentially with petroleum ether, carbon disulfide, ethanol, acetone-carbon disulfide mixture and tetrahydrofuran to obtain an extract and the treated petroleum coke, wherein the extract includes soluble organic matter. The method provided by the present disclosure employs extractants with different polarities, i.e., petroleum ether, carbon disulfide, ethanol, acetone-carbon disulfide mixture and tetrahydrofuran, to extract petroleum coke sequentially, so as to detect the composition of the soluble organic matter in petroleum coke at the molecular level, realizing the separation of soluble organic matter in petroleum coke at the macro molecular level, as well as the determination of molecular structure of soluble organic matter in petroleum coke by modern detection processes.
