Claim 4
Dependent Claim
26 words
The method of claim 1 wherein the temperature of the liquid feedstock stream is in excess of about 500*F. when intersected by the liquid water stream.
Claim 5
Dependent Claim
35 words
The method of claim 1 wherein the Delta T* between the liquid feedstock stream and the liquid water stream upon intersection of the two streams is within the range of about 300*F. to about 700*F.
Claim 6
Dependent Claim
34 words
The method of claim 1 wherein the volume ratio of the injected liquid feedstock hydrocarbon and the liquid water that is injected into it is within the range of about 4/1 to about 6/1.
Claim 7
Dependent Claim
60 words
The method of claim 1 wherein the furnace reaction chamber is elongated, the feedstock hydrocarbon is injected axially into the reaction chamber, free oxygen is introduced into the chamber as an air stream which surrounds the feedstock hydrocarbon stream, and the water stream is injected into the feedstock hydrocarbon stream following contact of the injected feedstock with the air stream.
Claim 8
Dependent Claim
76 words
The method of claim 8 wherein the funace reaction chamber is vertically elongated, the feedstock stream and the air stream are introduced axially upward into the chamber, a portion of the feedstock hydrocarbon is burned as fuel in producing the hot combustion gases within which the unburned portion of the feedstock hydrocarbon is thermally decomposed, and thermal decomposition of the feedstock occurs within a blanket which resides in the upper section of the furnace reaction chamber.
Claim 9
Dependent Claim
239 words
In an oil furnace process for producing a carbon black wherein a liquid stream of feedstock hydrocarbon is injected into a reaction chamber of a carbon black furnace and a portion of the feedstock hydrocarbon is burned with free oxygen in the reaction chamber, hot combustion gases are produced by the burning of the feedstock hydrocarbon, the remainder of the feedstock hydrocarbon is thermally decomposed by absorption heat from the hot gases thus formed, an aerosol is formed of carbon black suspended in the combustion gases and gaseous products formed by thermal decomposition of the hydrocarbon, and the carbon black is then separated and recovered from the gaseous constituents of the aerosol, the method of producing a carbon black having high electrical conductivity which comprises injecting a stream of liquid water into said liquid feedstock stream after injection of the feedstock into the furnace reaction chamber and during contact of the feedstock with free oxygen in the chamber, the volume ratio of injected feedstock hydrocarbon to injected water being within the range of about 3/1 to about 10/1, the liquid water being injected into the feedstock stream while the feedstock is still substantially in a liquid phase but after heating of the feedstock stream to a temperature which is substantially in excess of the water stream that is injected into it, and immediately burning the mixture which results upon injection of the water stream into the feedstock hydrocarbon stream.
Claim 10
Dependent Claim
26 words
The method of claim 10 wherein the temperature of the feedstock hydrocarboN stream is in excess of about 500*F. when intersected by the liquid water stream.
Claim 11
Dependent Claim
35 words
The method of claim 10 wherein the Delta T* between the liquid feedstock stream and the liquid water stream upon intersection of the two streams is within the range of about 300*F. to about 700*F.
Claim 12
Dependent Claim
34 words
The method of claim 10 wherein the volume ratio of the injected liquid feedstock hydrocarbon and the liquid water that is injected into it is within the range of about 4/1 to about 6/1.
