EPDM compositions comprising EPDM and specified carbon blacks which, when extruded or shaped, exhibit either a highly gloss or a textured matte finish. The carbon black is present in an amount of 100 to about 300, and more preferably about 150 to about 250, parts by weight per 100 parts by weight EPDM.

A method and an apparatus produce a product in at least one phase from an organic component in a feed gas stream. The method includes forming a process zone including a process molten bath and a process gas space disposed over the process molten bath. Molten droplets of said molten bath are then dispersed across the process gas space. The feed gas stream is then directed into the process gas zone, wherein the organic component is exposed to said molten droplets, thereby converting at least a portion of the organic component to a product in at least one phase. The apparatus of the invention comprises a reactor which includes a gas formation section, having a feed inlet, and means for retaining a solid feed component within the gas formation section. The apparatus also includes a process section, disposed in the reactor, having a process gas space, a gas outlet and a process molten bath disposed therein. Further, means are provided for dispersing molten droplets of said molten bath across the process gas space to expose an organic component in the feed gas stream to molten droplets.

A lance for submerged injection of a feed composition, such as a waste, into a molten metal bath includes a perforate refractory tube which extends substantially coaxially about an injection tube. The perforate refractory tube shields the injection tube from the molten metal bath during partial submersion of the lance into the molten metal bath. A perforate support liner extends between the injection tube and the perforate refractory tube and supports the perforate refractory tube. The perforate support liner and the injection tube define an annulus. The method includes conducting a coolant from a coolant source through the annulus to perforations defined by the perforate support liner and the perforate refractory tube, whereby coolant can be directed through the perforations and into the molten metal bath to cause a protective coating of metal to form on the lance. The lance is thereby protected, preserving its structural and chemical integrity during submerged injection of the feed composition through the injection tube into the molten metal bath.

A method and apparatus are disclosed for injecting liquids into a molten bath. The method includes forming a suitable liquid dispersion of a liquid phase disposed in a gas phase. The liquid phase has a ratio of surface area to volume which is sufficient to cause an accumulated amount of the liquid phase in the molten bath to be significantly less than that which would occur by injection of a continuous stream of the liquid into the molten bath. The liquid dispersion is directed into the molten metal bath, whereby the liquid volatilizes or decomposes. The rate at which the liquid dispersion is injected into the molten bath is sufficient to cause the liquid of the liquid phase to volatilize or decompose at a rate which is sufficient to cause the accumulation of the liquid phase in the bath to be significantly less than that which would occur by injection of a continuous stream of the liquid into the molten bath. The apparatus includes an atomizer which is disposed at a reactor containing the molten bath. The atomizer can be, for example, a tuyere which atomizes a suitable liquid to form a liquid dispersion of the liquid in a gas. The liquid dispersion is directed into the molten bath through the tuyere for volatilization or decomposition of the liquid.

A method for dissociating waste to its atomic constituents in a molten metal bath wherein the molten metal bath includes a refractory packing. The refractory packing is disposed in the molten metal bath to restrict the flow of waste and waste dissociation products through the molten metal and around the refractory packing to tortuous flow paths.

A reactor for dissociating waste in a molten metal bath includes a vertical reaction section for containing a molten metal bath and a horizontal separation section extending from an upper portion of the vertical reaction section. A waste is directed into the vertical section of the reactor. An oxidant is directed into the reactor for reaction with dissociation products of the waste to form gaseous, vitreous and molten metal reaction products in the molten metal bath. The horizontal separation section has discharge outlets for proximate and separate discharge of vitreous and molten metal product streams from the reactor at a location which is remote from the vertical reaction section. The vitreous and molten metal reaction products formed in the vertical reaction section flow from the vertical reaction section through the horizontal separation section to the discharge outlets, thereby promoting physical separation of the reaction products to form distinct gaseous, vitreous and molten metal product streams for separate discharge of the streams from the reactor.

Novel carbon blacks having an I.sub.2 No. of 26-34 mg/g; a CTAB of 26-34 m.sup.2 /g; a Tint of 46-54%; a DBP of 61-69 cc/100 g and a Dst/Dmode ratio of 1.31-136. Preferably the carbon blacks are additionally characterized by having a Number Median (D.sub.c /D.sub.p) of 2.7-3.1. Also disclosed are novel rubber and plastic compositions which, when the novel carbon blacks are incorporated therein, have lowered viscosity properties during subsequent processing.

Carbon Blacks

A process for preparing carbon blacks having lower-than-normal structure at a given surface area, and lower-than-normal surface area at a given overall combustion level. The process is carried-out by adding auxiliary hydrocarbons, which is hydrogen or any hydrocarbon having a molar hydrogen-to-carbon ratio greater than the molar hydrogen-to-carbon ratio of the feedstock, to the reaction zone of a carbon black reactor and adjusting the primary combustion and overall combustion so that the SSI of the process is less than zero.
