Abstract: A carbon black product comprises aggregates of carbon black characterized as having an OAN of between 139 and 149 ml/100 g, a COAN of between 95 and 105 ml/100 g, an iodine adsorption number I2 No of between 52 and 62 mg/g, and a multipoint nitrogen adsorption N2SA of between 54 and 64 m2/g. Tires manufactured with the carbon black product exhibit low rolling resistance and low heat build-up under service conditions.

Abstract: A nanospike hybrid carbon black product includes a plurality of carbon black aggregates. Each of the carbon black aggregates has a surface with a plurality of carbon nanospike formed thereon. The carbon nanospikes may each have a length between about 5 nm and 100 nm, and a width between about 5 nm and about 50 nm. A method for manufacturing the nanospike hybrid carbon black product includes the steps of injecting a primary carbon feedstock into a carbon black reactor, and combusting the carbon feedstock under a predetermined high temperature in the carbon black reactor to form carbon black aggregates. A catalyst is then deposited on surfaces of the carbon black aggregates. A secondary carbon feedstock is injected into the carbon black reactor, and reacted with the catalyst to grow carbon nanospikes on the surfaces of the carbon black aggregates.

Abstract: A chemically treated carbon black product is provided, which includes a pellet having an agglomerated mass of carbon black aggregates densified in a generally spheroidal form. The carbon black aggregates have polysulfide adsorbed on surfaces thereof. The polysulfide is thereby distributed throughout the pellet. Elastomeric compositions containing the chemically treated carbon black are also provided, and exhibit a reduction in hysteresis and equivalent or better abrasion resistance. A method for manufacturing the treated carbon black product is also disclosed.

Abstract: Carbon black is produced by introducing a carbon black feedstock, along with hot combustion gases, into the reaction zone of a carbon black furnace where the feedstock is partially burned and thermally decomposed to form carbon black. A hydrogen donor, such as ammonia gas, is simultaneously introduced into the reaction zone of the furnace from an extraneous source. The added hydrogen reduces the rate at which the carbon black feedstock is dehydrogenated. Carbon black aggregates produced in the reaction zone have surfaces characterized by reduced crystallite formation and an increased presence of amorphous carbon. The hydrogen content of the carbon black is also increased. This reduces the surface activity of the carbon black, making it more readily dispersible in elastomers, and improves the properties of such rubber compounds.
