    Abstract: Embodiments of the present disclosure generally relate to methods for preparing carbon materials which can be used in battery electrodes. In one or more embodiments, a method for preparing an anode carbon material is provided and includes combining a liquid refinery hydrocarbon product and a solvent to produce a first mixture, combining the first mixture and a first oxidizing agent containing an acid to produce a second mixture containing the liquid refinery hydrocarbon product, the solvent, and the first oxidizing agent, and heating the second mixture to produce a reaction mixture containing an oxidized solid product during an oxidation process. The method also includes separating the oxidized solid product from the reaction mixture during a separation process and carbonizing the oxidized solid product to produce a hard carbon product during a carbonization process.

    Abstract: The disclosure relates to a carbon-based electrode material that has been graphitized to hold ions in the electrode of a battery and more particularly include carbide or carbide and nitride surfaces that protect the graphite core. The preferred batteries include metal ion such as lithium ion batteries where the carbon-based electrode is the anode although the carbon-based electrode may also serve in dual ion batteries where both electrodes may comprise the graphitized carbon-based electrodes. The electrodes are more amorphous than conventional graphite electrodes and include a carbide or nitride containing surface treatment.

    Abstract: An oil in water analyzer for measuring the concentration of hydrocarbons in an effluent stream. The oil in water analyzer has a valve system for acquiring a sample from an effluent stream. An extraction device is used for mixing a known volume of a solvent and the sample to produce a hydrocarbon/solvent mixture. A second valve is used for transporting the hydrocarbon/solvent mixture to a spectroscopic cell. It is at the spectroscopic cell where the concentration of hydrocarbons in the hydrocarbon/solvent mixture is evaluated.
