A method of cracking hydrocarbon material in a nozzle reactor. The method includes a step of providing a nozzle reactor, a step of injecting a stream of cracking material into the reactor body of the nozzle reactor, and a step of injecting hydrocarbon material into the reactor body of the nozzle reactor, wherein the cracking material is methanol, ethanol, ethane, propane, biodiesel, carbon monoxide, nitrogen, or combinations thereof. The cracking material can also include steam. The hydrocarbon material can be injected into the reactor body at a direction transverse to the direction the cracking material is injected into the reactor body.

1. A method comprising: providing a nozzle reactor, the nozzle reactor comprising: a reactor body having a reactor body passage with an injection end and an ejection end;a first material injector having a first material injection passage and being mounted in the nozzle reactor in material injecting communication with the injection end of the reactor body, the first material 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 reactor body passage; anda second material feed port penetrating the reactor body and being adjacent to the material ejection end of the first material injection passage;injecting a stream of cracking material through the first material injector into the reactor body; andinjecting hydrocarbon material through the second material feed port into the reactor body;wherein the cracking material comprises from 90 to 99.9% methanol, ethanol, ethane, propane, biodiesel, carbon monoxide, or nitrogen. 2. The method as recited in claim 1, wherein the second material feed port is aligned transverse to a first material injection passage axis extending from the material injection end and material ejection end in the first material injection passage in the first, and wherein the hydrocarbon material is injected through the second material feed port into the reactor body in a direction transverse to the stream of cracking material entering the reactor body from the first material injector. 3. The method as recited in claim 1, wherein the cracking material is a gas prior to injection through the first material injector. 4. The method as recited in claim 1, wherein the cracking material is a liquid prior to injection through the first material injector. 5. The method as recited in claim 1, wherein the cracking material further comprises an additional material, the additional material comprising steam. 6. The method as recited in claim 1, wherein the hydrocarbon material comprises bitumen. 7. The method as recited in claim 1, wherein the hydrocarbon material comprises bitumen residue. 8. The method as recited in claim 1, wherein the enlarged volume injection section includes a converging central passage section, and the reduced volume mid-section and the enlarged volume ejection section include a diverging central passage section. 9. The method as recited in claim 8, wherein the converging central passage section, the reduced volume mid-section, and the diverging central passage section cooperatively provide a radially inwardly curved passage side wall intermediate the material injection end and material ejection end of the first material injection passage. 10. The method as recited in claim 1, wherein (a) the reactor body passage has a central rector body axis extending from the injection end to the ejection end of the reactor body passage and (b) the central reactor body axis is coaxial with a first material injection passage axis. 11. The method as recited in claim 1, wherein the enlarged volume injection section, reduced volume mid-section, and enlarged volume ejection section in the first material injection passage cooperatively provide a substantially isentropic passage for the stream of cracking material through the first material injection passage. 12. The method as recited in claim 1, wherein the second material feed port is annular. 13. The method as recited in claim 1, wherein the reactor body passage has a varying cross-sectional area and wherein the cross-sectional area of the reactor body passage either maintains constant or increases between the injection end and the ejection end of the reactor body passage. 14. The method as recited in claim 9, wherein the radially inwardly curved side wall in the first material injection passage is adapted to provide a substantially isentropic passage of the cracking material through the first material injector. 15. The method as recited in claim 1, wherein the cracking material is accelerated to supersonic speed by the first material injection passage of the first material injector. 16. The method as recited in claim 1, wherein injecting the hydrocarbon material into the reactor body includes injecting the hydrocarbon material into the reactor body annularly around the stream of cracking material. 17. The method as recited in claim 1, wherein the cracking material comprises from 90 to 99.9% methanol, ethanol, biodiesel, or carbon monoxide. 18. A method comprising: injecting a stream of cracking material through a cracking material injector into a reaction chamber, wherein the cracking material comprises 90 to 99.9% methanol, ethanol, ethane, propane, biodiesel, carbon monoxide, or nitrogen; andinjecting hydrocarbon material into the reaction chamber adjacent to the cracking material injector. 19. The method as recited in claim 18, wherein the hydrocarbon material is injected into the reaction chamber in a direction transverse to the stream of cracking material entering the reaction chamber from the cracking material injector. 20. The method as recited in claim 18, wherein the cracking material is a gas prior to injection through the cracking material injector. 21. The method as recited in claim 18, wherein the cracking material is a liquid prior to injection through the cracking material injector. 22. The method as recited in claim 18, wherein the cracking material further comprises an additional material, the additional material comprising steam. 23. The method as recited in claim 18, wherein the cracking material injector includes a converging/diverging passage and injecting a stream of cracking material through a cracking material injector into a reaction chamber includes passing the cracking material through the converging/diverging passage and accelerating the cracking material to supersonic speed within the cracking material injector. 24. The method as recited in claim 19, wherein injecting hydrocarbon material into the reaction chamber adjacent to the cracking material injector and transverse to the stream of cracking material entering the reaction chamber from the cracking material injector includes injecting the hydrocarbon material into the reaction chamber annularly around the pressurized stream of cracking material. 25. The method as recited in claim 18, wherein the cracking material comprises from 90 to 99.9% methanol, ethanol, biodiesel, or carbon monoxide.
