Abstract: Methods and systems for treatment of organic waste by means of hydrothermal carbonization include a mixing tank for receiving organic waste. A first batch of mixed wet waste is fed from the mixing tank to a first thermal reactor to undergo thermal hydrolysis. A second batch of mixed wet waste is fed from the mixing tank to a second thermal reactor to undergo thermal hydrolysis. Bio-char sludge is fed in an alternating manner from the first and second thermal reactors to a bio-char cooler. To save energy, hot and pressurized water from the first thermal reactor is subsequently supplied to the second thermal reactor or from the second thermal reactor to the first thermal reactor in an alternating manner for the respective hydrolysis processes.
Abstract: Direct thermal decomposition of hydrocarbons into solid carbon and hydrogen is performed by a process and a device. The process comprises preheating a hydrocarbon gas stream to a temperature between 500° C. and 700° C. and injecting the pre-heated hydrocarbon gas stream into the reactor pool of a liquid metal reactor containing a liquid media; forming a multi-phase flow with a hydrocarbon gas comprising hydrogen and solid carbon at a temperature between 900° C. and 1200° C.; forming a carbon layer on the free surface of the liquid media made up of solid carbon particles which are then displaced into at least one carbon extraction system and at least one recipient for collecting them; and, at the same time, the gas comprising hydrogen leaves the reactor pool through a porous rigid section, being collected at a gas outlet collector from where the gas comprising hydrogen finally leaves the liquid metal reactor.

Abstract: Sulfur-crosslinked olefins, particularly sulfur-crosslinked heavy hydrocarbon products having one or more sulfur-crosslinked olefin moieties, may undergo pyrolysis to form sulfur-doped porous carbon having high BET surface area values. Pyrolysis to form the sulfur-doped porous carbon may be particularly efficacious in the presence of a hydroxide base. BET surface areas up to 2000 m2/g or even higher may be obtained. Such sulfur-doped porous carbon may be prepared by combining a heavy hydrocarbon product with sulfur, heating to a first temperature state to form a liquefied reaction mixture containing a sulfur-crosslinked heavy hydrocarbon, homogeneously mixing a hydroxide base with the liquefied reaction mixture, and pyrolyzing the sulfur-crosslinked heavy hydrocarbon to form sulfur-doped porous carbon.

Abstract: A method is described to make a metal-containing non-amorphous hard-carbon composite material that is synthesized from furan-ring containing compounds. The metals described in the process include lithium and transition metals, including transition metal oxides like lithium titanates. The non-amorphous hard-carbon component of the metal-containing non-amorphous hard-carbon composite material is characterized by a d002 peak—in the X-ray diffraction patterns—that corresponds to an interlayer spacing of >3.6 ?, along with a prominent D-band peak in the Raman spectra. These metal-containing hard-carbon composites are used for constructing electrodes for Li-ion batteries and Li-ion capacitors.

Abstract: A biochar-derived adsorbent preferably from Sargassum boveanum, macroalgae can be used for removing phenolic compounds, such as 2,4,6-trichlorophenol and 2,4-dimethylphenol, from aqueous solutions. The carbonization can improve the removal capability of the macroalgae adsorbent for such phenolic compounds with removal efficiencies of 60% or more from high salinity seawater and 100% from distilled water. The adsorption may occur through a mixed mechanism dominated by physisorption following pseudo second-order kinetics. The adsorption of the phenolic molecules may be spontaneous, endothermic and thermodynamically favorable.
