Abstract:
1. A system for processing hydrocarbon materials, comprising: a hydrocarbon feedstock source; a process gas source; a waveguide configured to receive microwaves from a microwave generator and propagate microwave energy in a reaction tube; a reaction tube, wherein when hydrocarbon feedstock from the feedstock source and process gas from the process gas source are fed into the reaction tube and microwave energy from the waveguide is propagated in the reaction tube, a first plasma is formed within the reaction tube and the first plasma causes the feedstock and process gas to react and form into a product stream; a cleaning gas source configured to periodically, without stopping the propagation of the microwave energy from the waveguide into the reaction tube, deliver a cleaning gas comprising oxygen into the reaction tube and form a second plasma from the cleaning gas in the presence of the microwave energy so that the second plasma causes burning off of a carbon residue film from the reaction tube; and an extraction unit configured to extract the cleaning gas from the product stream and deliver the extracted cleaning gas to the cleaning gas source.
