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.
