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 I.sub.2 No of between 52 and 62 mg/g, and a multipoint nitrogen adsorption N.sub.2SA of between 54 and 64 m.sup.2/g. Tires manufactured with the carbon black product exhibit low rolling resistance and low heat build-up under service conditions.

The present invention discloses a reactor (100) for manufacturing carbon black, said reactor (100) comprising flow guide means (110) provided between a fuel burner (106) and an air inlet (108) for altering the flow path of combustion air entering at the air inlet (108) to result in a better mixing between the fuel and the combustion air, thereby, producing higher temperature hot combustion gases which are subsequently received in a reaction chamber (104) where they react with a carbonaceous feedstock to produce carbon black. The reactor (100) of the present invention increases the carbon black production by 5-20%. Further, the positioning of the flow guise means (110) stabilizes the flame from the fuel burner (106) to maintain it along the reactor axis, thus, increasing the life of the refractory lining (114).

A method for the production of a carbon black entirely from raw biomass feedstock by pyrolytically decomposing the biomass feedstock in a controlled processing atmosphere at a preselected temperature for a preselected period of time to produce solid carbon material and wood gas, and using the wood gas as a fuel to pyrolyze added oils in a carbon black furnace to produce carbon black and gaseous by-products for processing the biomass feedstock. The carbon material has a carbon content of greater than 90% by volume of non-volatile, high purity fixed elemental carbon, is free of environmentally hazardous chemical compounds and components surface area, and includes specific properties, such as density, hardness, or chemical composition to provide superior properties in diverse applications.
