Abstract

A nozzle reactor system for increasing the conversion rate of material feed injected into the nozzle reactor system. The system includes two or more nozzle reactors aligned in series, such that material exiting a first nozzle reactor may be injected into a second nozzle reactor, Each nozzle reactor includes an interior reactor chamber and an injection passage and a material feed passage that are each in material injecting communication with the interior reactor chamber. Furthermore, the injection passage is aligned transversely to the injection passage. The injection passage is configured to accelerate cracking material passed therethrough to a supersonic speed. A method of increasing the conversion rate of material feed utilizing multiple cracking steps is also described.

Dependent claims

A nozzle reactor system of the type useable to inject a first material and a second material to cause interaction between the first material and the second material, the nozzle reactor system comprising:

a first nozzle reactor, the first nozzle reactor comprising in combination:
a reactor body having an interior reactor chamber with an injection end and an ejection end;
an injection passage mounted in the nozzle reactor in material injecting communication with the interior reactor chamber, the injection passage having (a) an enlarged volume injection section, an enlarged volume ejection section, and a reduced volume mid-section intermediate the enlarged volume injection section and enlarged volume ejection section, (b) a material injection end, and (c) a material ejection end in injecting communication with the interior reactor chamber;
a material feed passage penetrating the reactor body and being (a) adjacent to the material ejection end of the injection passage and (b) transverse to an injection passage axis extending from the material injection end to the material ejection end in the injection passage;
and
a second nozzle reactor, the second nozzle reactor comprising in combination:
a reactor body having an interior reactor chamber with an injection end and an ejection end;
an injection passage mounted in the nozzle reactor in material injecting communication with the interior reactor chamber, the injection passage having (a) an enlarged volume injection section, an enlarged volume ejection section, and a reduced volume mid-section intermediate the enlarged volume injection section and enlarged volume ejection section, (b) a material injection end, and (c) a material ejection end in injecting communication with the interior reactor chamber;
a material feed passage penetrating the reactor body and being (a) adjacent to the material ejection end of the injection passage and (b) transverse to an injection passage axis extending from the material injection end to the material ejection end in the injection passage;
and
a first separation unit in fluid communication with the interior reactor chamber ejection end of the first nozzle reactor, the first separation unit comprising:
a light stream outlet;
and
a heavy stream outlet in fluid communication with the material feed passage of the second nozzle reactor.

A material cracking method comprising:

injecting a first stream of cracking material through a injection passage of a first nozzle reactor into an interior reactor chamber of a first nozzle reactor;
injecting a material feed into the interior reactor chamber of the first nozzle reactor adjacent to the injection passage of the first nozzle reactor and transverse to the first stream of cracking material entering the interior reactor chamber of the first nozzle reactor from the injection passage of the first nozzle reactor to produce first light material and first heavy material;
injecting a second stream of cracking material through an injection passage of a second nozzle reactor into an interior reactor chamber of a second nozzle reactor;
and
injecting the first heavy material into the interior reactor chamber of the second nozzle reactor adjacent to the injection passage of the second nozzle reactor and transverse to the second stream of cracking material entering the interior reactor chamber of the second nozzle reactor from the injection passage of the second nozzle reactor to thereby produce second light material and second heavy material.
