Pyrolysis | chemical reaction | Britannica

Pyrolysis, the chemical decomposition of organic (carbon-based) materials through the application of heat.Pyrolysis, which is also the first step in gasification and combustion, occurs in the absence or near absence of oxygen, and it is thus distinct from combustion (burning), which can take place only if sufficient oxygen is present. The rate of pyrolysis increases with temperature.

Why pyrolysis and 'plastic to fuels' is not a solution to .

Dec 04, 2018 · What have recently been called "plastics to fuels" concepts – using specific types of plastic only – are energy intensive chemical process plants which propose to use pyrolysis reactors. Time will tell if they can be made to work (again notwithstanding the fact that they are energy intensive).

Aspen Plus - Examples

Aspen RPLUG reactor model is used with reactor type Adiabatic Reactor and reaction model ISOMER. Aspen requires input of reactor dimensions in lieu of reactor volume.

The reactor comprises three main sections for: (i) drying, (ii) torrefaction and pyrolysis, and (iii) combustion of the PGVs.

Biochar Production Technologies - biochar-international

The reaction vessel is vented, to allow pyrolysis gases to escape. Pyrolysis gases are often called "syngas". The process becomes self-sustaining as the syngas produced is combusted, and heat isreleased. There are two types of pyrolysis systems in use today: fast pyrolysis and slow pyrolysis. Fast pyrolysis tends to produce more oils and .
