The fuel properties of pyrolytic oils obtained from catalytic pyrolysis of non-recyclable pulper rejects using activated natural minerals

In this study, catalytic pyrolysis of pulper rejects was performed with catalysts obtained from activated clinoptilolite and meerschaum for the production of pyrolytic fuel oils. The increasing proportion of polymers in rejects led to an increase in oil yield in non-catalytic process. The highest liquid (61.4%) and char (32.19%) yields were obtained using 15% clinoptilolite and 5% meerschaum, while the highest gas yield (21.44%) was obtained via the non-catalytic process. The fuel properties of the oils were significantly enhanced with the catalytic process. The clinoptilolite catalyst showed better performance compared to the meerschaum in terms of oil yield and fuel properties.
