Abstract: 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).

Abstract: The present disclosure envisages a process for pelletizing carbon black by mixing carbon black powder and water in a proportion in the range of 0.1:2 to 2:1 with a binding agent and a dispersing agent. The dispersing agent is an amine-based surfactant and is added in a proportion in the range of 0.005-0.1% of the total mixture. The mixture is pelletized in a pelletizer and subsequently the raw pellets are dried for 20-60 minutes at a temperature between 150-250° C., to obtain the carbon black pellets. The process of the present disclosure provides uniform distribution of water on the surface of the pellets giving a uniform pellet quality, reduced water consumption, energy savings and an increased production rate.

Abstract: The present invention provides a process for reinforced aluminum matrix composite. The aluminum matrix composite is reinforced with compound selected from the group consisting of Titanium carbide, Titanium boride, Vanadium and Zirconium compounds. The process is carried out pneumatically using pressurized carrier gas. The pressurized carrier gas also provides efficient stirring during the process which leads to uniform dispersion of the particulate in the aluminum matrix.
