    • A carbon black reactor adapted for producing fine control of the ''''structure'''' of the carbon black produced thereby by controlling the amount of axial gas which is fed with the hydrocarbon feedstock into the reaction zone of the reactor. In one embodiment, a controlled amount of process air is admitted into an annular conduit surrounding the feedstock inlet pipe through fine adjustment of the rotational position of an apertured surrounding sleeve. In another embodiment, a control valve adjusts the amount of axial air which is admitted with the feedstock.
    • 一种炭黑反应器,适用于通过控制将烃原料进料到反应器的反应区中的轴向气体的量来产生由此产生的炭黑的“结构”的精细控制。 在一个实施例中,受控量的处理空气通过微孔围绕套筒的旋转位置的微调而进入围绕原料入口管的环形导管中。 在另一个实施例中,控制阀调节用原料允许的轴向空气的量。

    • Apparatus and process for producing oil furnace carbon black of increased particle size by the thermal decomposition of select carbon-black-forming hydrocarbon feedstocks in an enclosed reactor having a refractory lined reaction tube with primary and secondary reaction zones. The upstream end of the reactor is a housing member with air inlet and being enclosed by an end plate, including a cylindrical baffle forming a plenum chamber communicating with perforated air diffusion plate having a central aperture mounted in flush alignment with the reaction tube. An axial burner and injection assembly extends through the end plate into the reaction tube. Air is introduced into the plenum chamber, through the diffusion plate to mix with hydrocarbon fuel for combustion and contact with the axially introduced oil feedstock in a primary reaction zone. A secondary reaction zone is established downstream by introducing preheated oxygen-containing gas from at least three tunnel burners extending through ports in the reactor housing and tube, said burners having axes focused at an angle 15* to 75* greater than and intersecting the reactor axis at the same point. The additional preheated oxygen-containing gas and combustion products introduced into the secondary reaction zone further oxidize the reaction products and surface condition the resulting carbon black. The total combustion products containing the suspended carbon black are quenched and recovered from the reactor for separation of the carbon black from said products.
