Disclosed herein are systems and methods for reducing the particulate matter content of an exhaust gas from a carbon black process.

The disclosure relates to a method for preparing a silica embedded carbon black composite aggregate and the silica embedded carbon black composite aggregate prepared thereby. The disclosure further relates to the use of the silica embedded carbon black composite aggregates in compositions such as rubber compositions.

The present disclosure provides, for example, systems and methods for generating carbon particles. Carbon particles may have a total content of polycyclic aromatic hydrocarbons of less than or equal to about 0.5 parts per million, a content of benzo[a]pyrene of less than or equal to about 5 parts per billion, and a water spreading pressure that is less than about 5 mJ/m.sup.2. A carbon particle among the carbon particles may comprise less than about 0.3% sulfur by weight or less than or equal to about 0.03% ash by weight.

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 guide 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).
