    摘要： Off-gas from a carbon black furnace is employed as a combustion gas feed stream to the burner or combustion zone of the same or a different carbon black furnace in accordance with certain embobiments, suitable conduit and valving is provided to pass off-gas, from which carbon black has been substantially removed, from any or all of multiple different carbon black furnaces to the burner. The off-gas is heated, preferably by plasma heating, and dewatered. Carbon dioxide stripping or rather stripping of gas components from the dewatered heated off-gas is found to be unnecessary to achieve economically favorable use of off-gas recirculation.

    摘要： A process for producing carbon black is provided and includes burning or gasifying a solid fuel and utilizing the heat, hot gases, or hot combustion gases resulting from the burning or gasification to pyrolyze a carbon black-yielding feedstock in a carbon black forming reactor. Through the use of a solid fuel, less hydrogen is produced as compared to the use of conventional hot combustion gas stream fuels and yields of carbon black can therefore be significantly increased. Preferably, a gaseous fuel formed from the gasification of a solid fueld such as coal, coke, petroleum coke, char, combinations thereof, or other solid fuel sources is used to form a hot combustion gas stream. A carbon black-yielding feedstock is injected into the stream of hot gases or heat resulting from the burning or gasifying to yield a stream of hot gases containing carbon black, which is then quenched. The use of a solid fuel source preferably provides a cleaner hot gas stream or heat that produces less deposits and residues than produced from processes using conventional fuels to form a stream of hot combustion gases.

    摘要： Carbon blacks having a CTAB of greater than, or equal to, 140 m2/g; a CDBP of greater than or equal to 115 cc/100g; a Tint value of greater than or equal to 135 %; a ΔD50 of less than or equal to 50 nm; a Dmode less than or equal to 72 nm; and an Occluded Volume Index greater than or equal to 1.30 that impart superior treadwear resistance and abrasion resistance to rubber compounds. Preferably, the carbon blacks of the present invention are further characterized by having a N¿2?SA greater than or equal to 150 m?2¿/g, and less than 180 m2/g; and a DBP of greater than or equal to 140 cc/100g. Also disclosed are rubber compounds containing the carbon blacks which exhibit increased abrasion resistance and treadwear resistance at normally utilized loading levels. Further disclosed are rubber compounds containing the carbon blacks which exhibit increased treadwear resistance/hysteresis ratios at loading levels lower than normally utilized in the compounding of tire compounds. All of the rubber compounds may additionally include silica in order to improve traction performance.
