NOVELTY - The reactor comprises a heating device for discharging an ionized gas into the reactor, a feedstock feeder (30) for injecting a feedstock material into the reactor, and a shell housing enclosing a part of the heating device and a portion of the feedstock feeder in forming an enclosed chamber (40). The heating device is configured to be kept electrically neutral for disassociating the feedstock material into gases. The feedstock feeder comprises a burner inserted into the chamber, and a portion of the burner is made of a material for withstanding high temperature.    USE - The reactor is useful for disassociating a feedstock material into gases and for converting a feedstock material into synthetic gases, and in a gasification device of an engine for providing electricity or propulsion, where: the engine is useful in a powertrain for providing locomotion to a vehicle (all claimed); the feedstock material includes hydrocarbon material of an organic mixture such as human waste, manure, forestry products, agricultural products, biodegradable materials and hydrocarbon of non-organic types having hydrogen or carbon, such as plastics, ammonia, water and hydrogen sulfide; and the gasification device is useful as a reformer for chemical process.    ADVANTAGE - The reactor is economical and stable to operate and easy to maintain.    DETAILED DESCRIPTION - The reactor comprises a heating device for discharging an ionized gas into the reactor, a feedstock feeder (30) for injecting a feedstock material into the reactor, and a shell housing enclosing a part of the heating device and a portion of the feedstock feeder in forming an enclosed chamber (40). The heating device is configured to be kept electrically neutral for disassociating the feedstock material into gases. The feedstock feeder comprises a burner inserted into the chamber, and a portion of the burner is made of a material for withstanding high temperature. The burner comprises internal channels for feeding the feedstock material into the chamber. A component of the burner is adjacent to the heating device such that flames of the ionized gases are configured to touch the burner for disassociating the feedstock material. The burner further comprises an Archimedean screw feeder and a feedstock propeller coupled together for injecting the feedstock material into the reactor. The Archimedean screw feeder comprises a feeding screw fitted inside a feeding sleeve for propelling the feedstock material (90) between teeth of the feeding screw and teeth of feeding sleeve. The Archimedean screw feeder and the feedstock propeller are supported on a wall bracket bearing and a screw bearing respectively for rotating the feeding sleeve and/or the feeding screw. The shell comprises a heat exchanger that is connected to a portion of the shell for cooling the shell. The reactor further comprises a slag collector for collecting and disposing solid waste, and a regulator. The shell seals the chamber hermetically such that the reactor is configured to operate at negative pressure or positive pressure. The regulator is connected: to the feedstock feeder, the heating device and/or an inlet for controlling molecular disassociation 25 process in the chamber; to a temperature sensor inside the chamber for monitoring an internal temperature of the reactor and/or a pressure sensor of the pressurized gas loop; to a feeding valve on a feeding tube of the feedstock feeder for adjusting flow rate of the feedstock material; and to a discharging valve on the inlet for governing flow rate of the synthetic gas. INDEPENDENT CLAIMS are included for:    (1) a gasification device;    (2) an engine for providing electricity or propulsion; and    (3) a method for converting a feedstock material into synthetic gases.
