Hydrous Pyrolysis Of Plastics

Hydrous pyrolysis Wikipedia

Hydrous pyrolysis refers to the thermal decomposition which takes place when organic compounds are heated to high temperatures in the presence of water.. Many hydrous pyrolysis processes use superheated water in the liquid phase, whereas steam cracking uses water in the gas phase. Steam cracking is used in the petroleum industry to produce the lighter alkenes.

Hydrous Pyrolysis an overview ScienceDirect Topics

Thermal depolymerization is used to convert various waste products, usually, plastic and biomass, into light crude oil by using hydrous pyrolysis. Long-chain polymers of oxygen, hydrogen, and carbon decompose into short-chain petroleum hydrocarbons once pressure and heat applied [212].

Pyrolysis Wikipedia

Pyrolysis can also be used to treat plastic waste. The main advantage is the reduction in volume of the waste. In principle, pyrolysis will regenerate the monomers (precursors) to the polymers that are treated, but in practice the process is neither a clean nor an economically competitive source of monomers.

What is Thermal Depolymerization? (with picture)

2019-10-23· In practice, the hydrous pyrolysis process at the heart of thermal depolymerization is fairly simple. Feedstock materials are first ground into small pieces and mixed with water. The mixture is then heated to 482°F (250°C) for approximately 15 minutes in a pressure vessel. The steam generated raises the pressure in the vessel to approximately
