Characteristics and kinetics of cattle litter pyrolysis in a tubing reactor

초록

The kinetic parameters for the pyrolysis of cattle litter were evaluated by thermogravimetric analysis (TGA). The cattle litter was pyrolyzed in a tubing reactor at 340, 360 and 380 degrees C with various retention times from 4 to 20 min. The influence of the pyrolysis conditions on the product yields was also examined. The maximum yields of gas and liquid products, 16.1 and 17.2 wt% respectively were obtained,, after pyrolysis at 380 degrees C for 20 min. The gas products were mainly C-1-C-4 hydrocarbons. The experimental results of the product distribution were well fitted with the lumped kinetic model. The reaction pathway was investigated based on the calculated kinetic constants.
