Production of Bio-oil by Oxidative Pyrolysis of Sewage Sludge in Rotating Fixed Bed Reactor
Pyrolysis is an attractive thermal conversion technology used to produce bio-oil and some chemicals. In this study, we investigated the pyrolysis of sewage sludge under N2 and CO2 atmosphere at various temperatures (350-750°C) in a rotating fixed bed reactor. For under N2 atmosphere, thermal gravimetric analysis (TGA) shows two major reaction peaks centered at 300 and 500°C. However, if CO2 was...
متن کاملbio-oil production from fast pyrolysis of corn wastes and eucalyptus wood in a fluidized bed reactor
fast pyrolysis is an attractive technology for biomass conversion, from which bio-oil is the preferred product with a great potential for use in industry and transport. corn wastes (cob and stover) and eucalyptus wood are widely being produced throughout the world. in this study, fast pyrolysis of these two materials were examined under the temperature of 500 °c; career gas flow rate of 660 l h...
متن کاملPressurised pyrolysis of Miscanthus using a fixed bed reactor.
Miscanthus x giganteus was pyrolysed, in a fixed bed reactor in a constant flow of dinitrogen gas, at a rate of 13°C/min from ambient to 550°C, then held for 25 min at this temperature. The pressures employed ranged from atmospheric to 26 bar. The major compounds identified in the bio-oil were water, phenol, and phenol derivatives. The water contents impact on the usefulness of the bio-oil as a...
متن کاملCharacterization of Japanese cedar bio-oil produced using a bench-scale auger pyrolyzer
A bench-scale auger reactor was designed for use as a laboratory-scale fast pyrolyzer for producing bio-oil from Japanese cedar. An analytical pyrolysis method was performed simultaneously to determine the distribution of pyrolysis products. The pyrolysis temperature was found to have the greatest influence on the bio-oil characteristics; bio-oil yields increased as the pyrolysis temperature in...
متن کاملProduction of Activated Carbon from Palm-oil Shell by Pyrolysis and Steam Activation in a Fixed Bed Reactor
The research objective was to produce activated carbon from palm-oil shells by one step pyrolysis and steam activation in a fixed bed reactor with the diameter of 100 mm. The studied variables were activation temperature, activation time, palm-oil shell sizes and flow rate of air. The results showed that the optimum condition was 1.18-2.36 mm of palm-oil shells at 750C for 2 hr with air flow ra...
