How it works

The CAT-HTR technology uses water at supercritical conditions to break down the rubber components into useful products and chemicals.

The heat and pressure in the reactor breaks down the polymeric bonds in rubber creating short-chain, stable, useful hydrocarbons. Water molecules are split, and the hydrogen released is used to produce new hydrocarbons. Steam, carbon dioxide and hydrogen gases are produced on the process. The remaining liquid is forwarded to a separation system which separates fine impurities from the oil and water. The oily water emulsion is then further separated to produce the oil and chemical products.

The waste gases are recovered for re-use within the process, while the product is separated from the water and transferred to product storage tanks. Heat energy and water are recovered and re-used to maximise process efficiency. The product can then be shipped in bulk or processed further depending on client requirements.

The CAT-HTR technology is unique when compared to every other hydrothermal conversion process, as it uses water as the ‘agent of change’, so the plant can operate at far lower temperatures making it more energy efficient than other traditional cracking processes such as pyrolysis or gasification. In addition, the process is less polluting to the environment that these methods as it does not produce unwanted bi-products, including ash, dioxins or other toxic compounds.
