Twin Screw Reactor Design for Biomass Pyrolysis

Languages of publication
The process of fast pyrolysis using biomass to produce bio-oil or pyrolysis oil for application as an energy source and a chemical feedstock is of interest in this study. The literature on biomass fast pyrolysis is surveyed here and how parameter such as feed rate, temperature, rate of heating, and residence time affects the process. Investigation for this work includes the pyrolysis of sawdust and bagasse through fast pyrolysis in an auger reactor. Temperatures between 350 C and 450 C have been applied to characterize the yields and reactor problem has been identified. This work reports the problems faced with the twin screw reactor, troubleshooting which will result in bio-oil, one of the main products of fast pyrolysis. System produced solid biofuel or bio-char much of which is in the research phase as a climate change mitigation tool. Further use of professional CAD software to model and optimize the system has also been covered. Based on which suitable design changes are also developed to overcome the problems. Analysis of feed material and the solid biofuel is covered in this work as well. Pyrolysis experiments can be done using a wide range of biomass feeds. But not much of it has been studied in twin screw reactors. This scant knowledge over the study of such alternative fuel has been the reason to look into this activity.
