Abstract: All of the hot effluent reducing gas from a partial oxidation reducing gas generator is mixed with a comparatively cooled and cleaned portion of the reducing gas to produce a stream of improved reducing gas at the proper temperature for injecting into an ore reduction zone e.g., iron-ore blast furnace. Optionally, cooled, cleaned and purified off-gas from the ore reduction zone may be mixed with the reducing gas.

Abstract: Process for the production of a methane-rich gas stream from a hydrocarbonaceous feedstock with all steps being carried out at or slightly above the desired pressure of delivery. Effluent gas from a free-flow partial-oxidation synthesis-gas generator, and preferably containing from about 10-26 volume percent methane on a dry basis is reacted with steam and without a catalyst at a temperature in the range of 2,800 to 1,500* F. to produce a stream of shifted gases having a mole ratio H2/CO in the range of 1.5 to 4 and preferably about 3. The shifted gases are then processed by the steps of scrubbing with a liquid hydrocarbon to recover particulate carbon, cooling to condense out water and volatile hydrocarbons, purifying by eliminating H2S and CO2 in a separation zone, and catalytically reacting the remaining H2 and CO in the process gas stream to produce a process gas stream comprising at least 45 volume percent methane on a dry basis.

Abstract: This disclosure pertains to a triple-orifice burner and process for atomizing a stream of normally liquid hydrocarbon with a separate stream of free-oxygen-containing gas a finite distance downstream from the tip of the burner and for simultaneously enveloping the mixed streams with a separate stream of temperature-moderating gas so that none of the three streams comes into contact with any other gas with which it is combustible until it reaches a distance downstream from the tips of the burner orifices beyond that close enough to cause appreciable deterioration of the tips when reaction takes place in a free-flow partial oxidation gas generator at a temperature in the range of about 1,200* to 3500*F. and at a pressure in the range of about 1 to 275 atmospheres to produce a gaseous mixture comprising principally H2 and CO, e.g., synthesis gas, reducing gas, or fuel gas. While the liquid hydrocarbon is passed through the burner at a velocity in the range of about 10 to 100 feet per second, both the stream of free-oxygen-containing gas and the stream of temperature-moderating gas may be passed through the burner at velocities up to sonic velocity when it is desired to offset the effects of variable back pressure in the gas generator. The burner comprises three coaxial concentric nozzles whose tips are recessed from the downstream tip of the burner and which discharge into a single unobstructed coaxial central outwardlydiverging passage with an annular face of convex configuration at the extremity of the downstream tip of the burner. An imaginary plane tangent to said annular face at its outermost extremity is normal to the burner axis. The three nozzles provide, respectively, a central passage with a circular opening for discharging a stream of liquid hydrocarbon, an intermediate converging annular passage for discharging a stream of freeoxygen-containing gas, and an outer converging annular passage for discharging a stream of temperature-moderating gas, such as steam. An annular coolant chamber is disposed about the outside periphery of said outer discharge passage and downstream burner tip.

Abstract: This is a process for the production of synthesis gas substantially free from entrained particulate carbon. The product gas is preferably produced substantially free from volatile hydrocarbon contaminants. A feedstock comprising fresh liquid hydrocarbon oil is introduced into a distillation zone and separated into a light liquid hydrocarbon fraction and a heavy liquid hydrocarbon fraction. The light hydrocarbon fraction in admixture with a preheated slurry produced subsequently in a gas scrubbing zone and comprising particulate carbon and said heavy liquid hydrocarbon fraction are introduced into the reaction zone of a free flow noncatalytic synthesis gas generator and reacted by partial oxidation with oxygen and steam at an autogenous temperature in the range of 1,500*-3,000* F. to produce synthesis gas comprising hydrogen, carbon monoxide, and appreciable amounts of entrained particulate carbon. The effluent gas from the reaction zone is cooled by indirect heat exchange and is then scrubbed free of said entrained particulate carbon in a gas scrubbing zone with said heavy liquid hydrocarbon fraction and carbon slurries thereof. The scrubbing zone is preferably maintained at a temperature and pressure so that undue stripping of volatile fractions from the scrubbing fluid is prevented. When desired, water and any vaporized hydrocarbon in the overhead from the scrubber may be condensed out and separated from the product gas stream.
