A method for the pyrolysis of raw materials, especially raw materials deriving from tires or bitumen, includes the steps of feeding the material to be subjected to the pyrolysis process to a reactor; heating the material in the reactor at a temperature needed to establish the pyrolysis process; collecting the final products of the pyrolysis reaction; separating the gaseous, liquid and solid phases of the reaction products; and storing, for further treatment, the reaction products separate one from another. The heating in the pyrolysis process to the activation temperature is obtained by irradiating the raw material with laser radiation, concentrated or focused on a localized area of a pre-established surface area on the mass of raw material of the focusing area, and progressively moved along the entire surface of the mass of raw material to activate the pyrolytic reaction on all the mass of raw material.

A coke oven includes an oven chamber configured to support and heat a coal bed, a castable slab below the oven chamber, and a foundation supporting the heat recovery oven. One or more beams are positioned between the castable slab and the foundation. The beams extend from a first end of the oven chamber to a second end of the oven chamber, forming a plurality of air gaps between the castable slab and the foundation. Heat from the oven chamber is dissipated by the one or more beams.

The present technology describes methods and systems for an improved quench tower. Some embodiments improve the quench tower's ability to recover particulate matter, steam, and emissions that escape from the base of the quench tower. Some embodiments improve the draft and draft distribution of the quench tower. Some embodiments include one or more sheds to enlarge the physical or effective perimeter of the quench tower to reduce the amount of particulate matter, emissions, and steam loss during the quenching process. Some embodiments include an improved quench baffle formed of a plurality of single-turn or multi-turn chevrons adapted to prevent particulate matter from escaping the quench tower. Some embodiments include an improved quench baffle spray nozzle used to wet the baffles, suppress dust, and/or clean baffles. Some embodiments include a quench nozzle that can fire in discrete stages during the quenching process.

The techniques introduced here include a system and method for efficiently, and in some embodiments automatically, processing solid organic waste. In both the method and the system the solid organic waste is injected into a rotating, thermally isolable, container with internal sensors that help in keeping humidity and temperature within given parameters, before the resulting dried solid organic waste is sent to a pyrolysis chamber and its exhausts are sent to filter. In some embodiments, inert material in the form of dried solid organic waste is left in the container in order to make the process even more efficient and system and process are made automatic and remotely controllable through the use of software automation and a web of internal and external sensors.
