An apparatus and process for thermally de-manufacturing tires and other materials. The apparatus is a retort chamber with various zones in which tires are combusted to provide energy for the thermal depolymerization reaction, depolymerization takes place, and products leave the retort chamber. In one embodiment, the process reacts water with iron present in steel-belted tires to produce hydrogen, which helps to break sulfur-sulfur bonds in vulcanized materials. The water also helps control the temperature of the reaction, which allows for control over the types and relative amounts of the various depolymerization products.

This invention relates to a method and apparatus for gasifying or liquifying coal. In particular, the method comprises reacting a coal with a molten aluminum or aluminum alloy bath. The apparatus includes a reaction vessel for carrying out the reaction, as well as other equipment necessary for capturing and removing the reaction products. Further, the process can be used to cogenerate electricity using the excess heat generated by the process.

Methods and systems are described for the synthesis of graphene, synthetic graphite, and other carbon allotropes. Thus, the method describes a method to synthesize carbon nanostructures and synthetic graphite by using unrecyclable materials, such as plastic wastes (i.e., Polypropylene, Styrene, Polyethylene, Poly Vinyl Chloride, PVDF, tires, etc.), Liquid wastes (i.e. tank bottoms, PVDF liquid foams, contaminated oils, etc.) (unrecyclable carbons) regardless of its state, cleanliness, or whether it is contaminated with other byproducts.

Disclosed is a method for heating a biomass moving along an industrial treatment line including an inlet (1) for the incoming biomass, a heating unit (4), and a treatment station (5). A fraction of the biomass heated by the heating unit (4) is returned along a return branch (R) to a mixing station (2) upstream of the heating unit (4) so as to form, together with the incoming biomass, a mixture having a temperature above the temperature of the incoming biomass, the heated biomass fraction being removed at an outlet (51) of the treatment station (5).
