The effects of the heating rate on the pyrolysis behavior of empty fruit bunch biomass

Pyrolysis is a process to have fuel from biomass. Performance of this process was influenced by some variables which are heating rate, operating temperature, species of biomass, time and particle size. These parameters will affect the product conversion or performance in terms of its percentage of v...

Results from experiment conducted showed that at the lower values of this interval of heating rate, the maximum rates of mass losses were so low that they were only 5.6%/min for 5°C/min, and 8.0%/min for 10°C /min. As the heating rate increased, rates of maximum mass losses also increased so that they were determined as 15.6, 25.7 and 35.2%/min for the heating rates of 20, 40 and 60 °C/min, respectively. Total mass losses from the sample were determined as 87.1, 62.8, 61.7, 59.1, and 51.7% at heating rates of 5, 10, 20, 30, 40 and 60 °C /min.
