A method of tire recycling, the method comprising the steps of: a) a hybrid plasma torch comprising an arc plasma torch and a radio frequency (RF) plasma torch generating a plasma jet in a first direction; b) injecting rubber powder obtained from comminuting waste tires into the plasma jet in a second direction against the first direction and obtaining a synthesis gas (syngas) by plasma pyrolysis of the rubber powder; c) heating unpyrolyzed rubber powder remaining after step b) in a low frequency (LF) induction heater to obtain carbon black; and d) using a portion of the obtained syngas as plasma gas by the hybrid plasma torch.

A method for carbon capture and recycling, the method including the steps of: (i) Capturing CO.sub.2 from at least one CO.sub.2 containing input; (ii) Producing a CO.sub.2 feed stream from the captured CO.sub.2; and (iii) Reacting the CO.sub.2 feed stream with a H.sub.2 feed stream to produce a methane containing output.

A gasifier, including a vertically disposed furnace body, a monitoring unit, and a microwave plasma generating device. The furnace body includes a material and fuel inlet, a syngas outlet, an oxygen/vapor inlet, and a slag outlet. The furnace body has a clearance zone in an upper part thereof and a fixed bed zone in a lower part thereof. The slag outlet is disposed at the bottom of the furnace body. The monitoring unit is disposed close to the syngas outlet. At least one microwave plasma generating device is disposed on the furnace body.

A hybrid plasma reactor system that uses multiple sets of long electrodes that are placed longitudinally opposite each other within modular plasma units. The plasma units can be stacked to form an elongated plasma zone. The electrode assemblies extend into access ports. Each of the electrode assemblies has an electrode tip mounted in a tubular support jacket. A gas conduit for a supplied working gas surrounds at least a portion of the tubular support jacket. An arc is created at the electrode tip. A working gas flows through the gas conduit and is directed into the arc, therein creating plasma within the internal plasma zone.

A rotating heat regenerator is used to recover heat from the syngas at it exits the reactor vessel of a waste or biomass gasifier. In some embodiments, three or more streams are passed through the heat exchanger. One stream is the dirty syngas, which heats the rotating material. A second stream is a cold stream that is heated as it passes through the material. A third stream is a cleaning stream, which serves to remove particulates that are collected on the rotating material as the dirty syngas passes through it. This apparatus can also be used as an auto-heat exchanger, or it can exchange heat between separate flows in the gasifier process. The apparatus can also be used to reduce the heating requirement for the thermal residence chamber (TRC) used downstream from the gasification system.

A two-step gasification process and apparatus for the conversion of solid or liquid organic waste into clean fuel, suitable for use in a gas engine or a gas burner, is described. The waste is fed initially into a primary gasifier, which is a graphite arc furnace. Within the primary gasifier, the organic components of the waste are mixed with a predetermined amount of air, oxygen or steam, and converted into volatiles and soot. The volatiles consist mainly of carbon monoxide and hydrogen, and may include a variety of other hydrocarbons and some fly ash. The gas exiting the primary gasifier first passes through a hot cyclone, where some of the soot and most of the fly ash is collected and returned to the primary gasifier. The remaining soot along with the volatile organic compounds is further treated in a secondary gasifier where the soot and the volatile compounds mix with a high temperature plasma jet and a metered amount of air, oxygen or steam, and are converted into a synthesis gas consisting primarily of carbon monoxide and hydrogen. The synthesis gas is then quenched and cleaned to form a clean fuel gas suitable for use in a gas engine or a gas burner. This offers higher thermal efficiency than conventional technology and produces a cleaner fuel than other known alternatives.

An apparatus for waste recycling that is suitable for residence building level in both volume and rate of supply of waste with a waste disposal and treatment container having the following parts: waste eliminator comprising a thermally and acoustically insulating casing with odour insulating raw waste receiving space; all-purpose shredder and crusher; crushed and/or shredded waste conveyor; liquid waste purifier; gasification plasma reactor; gas conveyor and purifier; slag collector; re-hydration means for re-hydrating solid waste in the gasification plasma reactor; and safety means. Each one of these parts is organized in fluid communication with its neighbor parts.

A method of producing syngas wherein a carbonaceous feedstock is exposed to a plasma arc generated by a DC supply in a dry-steam environment.

A system for gasification of a material includes a plasma generator interfaced to a reaction chamber. A feedstock such as pulverized coal is fed into a plasma jet created by the plasma generator and is gasified by the high temperatures of the plasma jet. The gas produced is then collected, filtered, and utilized, for example, in generating of electricity. Likewise, extra heat produced by the system is also used to generate electricity or other heating purposes
