The process takes place in the absence of oxygen at increased pressure and temperature for a short duration Pyrolysis process is proposed by many researchers since the process is able to produce large quantity of liquid oil up to 80 wt% at temperatures around 500°C [9] The process parameters can be altered to generate products based on ....
Pyrolysis/Gasification: Technology Overview Pyrolysis is a process that decomposes materials at moderately elevated temperatures in an oxygen-free environment Gasification is similar to pyrolysis but uses small quantities of oxygen, taking advantage of the partial combustion process to provide the heat to operate the process...
• Pyrolysis is achieved by using an external heat source such as exhaust gas, electrical energy etc, However, the process is unsuitable for pyrolysis since 1) There is no control over the products in an integrated systems 2) If a non-reacting medium such as N2 is used for heat transfer & uniform heating, there is the problem of purification ....
“Pyrolysis,” in the context of this paper, is defined as thermal decomposition in an oxygen-free environment Primary pyrolysis reactions are those which occur in the initial stages of thermal decomposition, while secondary pyrolysis reactions are those which occur upon further heat treatment A pyrolysis based process has several...
