A process and an apparatus for pyrolysis of mixed plastic feedstock producing petroleum products are described. In one example, a process for producing petroleum products includes charging feedstock of mixed polymer materials into a reactor apparatus. Heat energy is applied to the feedstock while advancing the feedstock through the reactor apparatus in an anaerobic operation. The energy input to the reactor apparatus is controlled by controlling a temperature gradient within the reactor vessel to produce petroleum gas product. The process involves in situ chemical reactions comprising cracking and recombination reactions that that are controlled to convert solid hydrocarbonaceous portion of the feedstock to molten fluids and gases inside the reactor vessel and to produce gaseous petroleum products which exit the reactor vessel. The separated solid residue from the pyrolysis process is also removed from the reactions vessel.

The present technology is generally directed to systems and methods for optimizing the burn profiles for coke ovens, such as horizontal heat recovery ovens. In various embodiments the burn profile is at least partially optimized by controlling air distribution in the coke oven. In some embodiments, the air distribution is controlled according to temperature readings in the coke oven. In particular embodiments, the system monitors the crown temperature of the coke oven. After the crown reaches a particular temperature range the flow of volatile matter is transferred to the sole flue to increase sole flue temperatures throughout the coking cycle. Embodiments of the present technology include an air distribution system having a plurality of crown air inlets positioned above the oven floor.

A high temperature carbonization furnace has a cavity, at least two microwave units and a control unit. Each microwave unit is disposed along a processing path of the cavity. The control circuit receives signals of temperature sensors distributed on the processing path of the cavity. The control unit generates controls signals to control magnetrons of the different microwave units to be turned on/off, or to control powers of the magnetrons of the different microwave units, such that a location of the processing path, on which the microwave unit disposed, can attain an expected temperature condition. Further, the temperatures in the cavity can be adjusted precisely, such that the temperature distribution in the cavity is uniform, the uniformity for heating the processing object can be increased, and the temperature gradient of different temperature control regions can be controlled and adjusted, so as to achieve the advantage of adjusting and controlling the temperature condition of the processing path according to the requirement of the processing object.
