Systems and integrated methods are disclosed for processing aromatic complex bottoms into high value products. The system includes an adsorption column, the adsorption column in fluid communication with an aromatics complex and operable to receive and remove polyaromatics from an aromatic bottoms stream. The adsorption column producing a cleaned aromatic bottoms stream with reduced polyaromatic content and a reject stream including the removed polyaromatics. In some embodiments, the reject stream is recycled for further processing, passed to a coke production unit to produce high quality coke, or both.

The device for pyrolysis of carbonaceous materials comprises a working chamber comprising a non-magnetic wall comprising an inner graphite lining; one or more electrodes adapted to be inserted within a carbon-based bedding; a solenoid coiled around the device exterior, the solenoid adapted to create a magnetic field within the working chamber such that when the solenoid is energized, the carbon-based bedding is caused to move; a lower solids outlet comprising an airlock, the solids outlet adapted to permit solids to exit the device; and a lower gas outlet adapted to permit gaseous substances to exit after having traveled through the carbon-based bedding. The method comprises the steps of loading carbon-containing materials into the working chamber; using the first and second electrodes to heat the carbon-containing materials by passing electric current through the carbon-containing materials without air access; collecting, cleaning and releasing gaseous pyrolysis products produced by the heating.

Thermolysis method implementing the installation.

The invention relates to a method for producing syngas in combined operation with a metallurgical plant which comprises at least one blast furnace for producing crude iron, a converter steel mill and a coke-oven plant. Part of the blast-furnace top gas that is produced in the production of crude iron and/or part of the converter gas that occurs in the converter steel mill and/or part of the coke-oven gas that is produced in the coke-oven plant are mixed. By choosing the gas streams that are brought together to form a mixed gas and/or by changing the mixing ratios of the gas streams that are brought together, at least two streams of useful gas are produced, differing with regard to their composition and respectively prepared to form streams of syngas.
