    Abstract: A high-temperature chemical reaction process is performed in which a finely-divided volatile carbonaceous reductant is intimately mixed with finely-divided transition metal compounds and introduced, in entrained flow, into a strong radiative environment, inducing preferential heating of the solids and causing gasification of the volatile carbonaceous reductant principally to carbon monoxide gas and hydrogen gas. The gases in turn reduce the metal compounds to their parent metals. Nonvolatile metals in the form of small solid spheres are readily separated from their physical mixtures with spherical inorganic slags, making the process useful for the reclamation of metals from spent catalysts and low-grade ores. Because of the heterogeneous temperature distribution in the stream, reduced volatile metals are readily distilled out of nonvolatile melts, and condense in the cooler gas component of the stream as fine powders which are easily separated from the larger nonvolatile metal and slag fractions. This property of the process is particularly useful in the reclamation of metals from electric arc furnace dust.

    Abstract: A reactor tube for a high temperature chemical reactor having a precisely controllable porosity comprises a plurality of layers of a fabric of a fibrous refractory material such as carbon or graphite cloth. Difficulties connected with the handling of carbon cloth, which has an extremely high coefficient of friction, are substantially eliminated by winding the cloth on a mandrel to form the reactor tube. After winding, the mandrel is contracted, allowing its removal without damaging the inside surface of the tube. Heating elements for the high temperature chemical reactor are also formed by winding carbon cloth on a mandrel. A preferred embodiment of the reactor contemplates that a plurality of such heating elements be positioned radially outwardly of the reactor tube.

    Abstract: A fuel converter for a transportation vehicle includes a fuel container for a hydrocarbon fuel, an auxiliary container for water or for an inert fluid which is substantially transparent to radiant energy, an electrical power source, and a high temperature fluid-wall reactor.The high temperature fluid-wall reactor has at least one input for the hydrocarbon fuel and for water or the inert fluid, an electrical power input, and an output. Means are provided for metering the hydrocarbon fuel, water or the inert fluid, and electrical power into the appropriate inputs of the reactor. A manifold connects the output of the reactor to a combustion fuel input of the engine of the vehicle. By means of the fuel converter, a variety of low grade and inexpensive hydrocarbon fuels may be converted into combustible mixtures such as carbon black and hydrogen or carbon monoxide and hydrogen which are suitable as fuel for an internal combustion engine. The level of hydrocarbon pollutants in the exhaust of the engine is substantially reduced relative to the exhaust from the engine when burning an unmodified hydrocarbon fuel.

    Abstract: A high-temperature, fluid-wall chemical reactor can be equipped with a variable profile, counterflow heat exchanger and a reaction product control system. The heat exchanger includes two tubular walls, positioned concentric of one another, and a spiral baffle disposed between the two walls to define a spiral, annular coolant channel. The walls and baffle are made of a refractory material. The heat exchanger has an inlet and an outlet to permit a coolant to be circulated through the coolant channel. The reaction product control system includes a reaction product analyzer and means for withdrawing and transferring samples of reaction product exiting the reactor. The reaction product analyzer can receive samples of reaction product and generate a signal corresponding to deviations between the chemical composition of the product and a preselected composition. The control system also includes a reactor temperature controller to vary a temperature of the reactor in response to the signal from the reaction product analyzer to reduce the deviations.
