Effect of Temperature and N-Doping on the Distribution of Bamboo Waste Pyrolysis Products Using Quartz Tube Furnace

Abstract

This study investigates the effect of temperature and nitrogen doping (N-Doping)  on the pyrolysis of bamboo waste to optimize the distribution of biochar, bio-oil, and gas products. Bamboo waste as raw material was applied to pyrolysis in a quartz tube furnace reactor at temperatures of 300°C, 400°C, 500°C, and 600°C under two atmospheric conditions: pyrolysis with nitrogen (PN) and pyrolysis without nitrogen (PWN). The results showed that the maximum bio-oil yield achieved of 55.32% at 500°C under pyrolysis with nitrogen (PN), while the maximum bio-oil yield achieved of 52 % at 500°C under pyrolysis without nitrogen (PWN).  Nitrogen doping can increase bio-oil production by preventing oxidation and reducing secondary reactions. In addition, PWN conditions produced higher biochar yields due to partial oxidation. Gas yields increased at higher temperatures in both conditions, which was caused by thermal cracking and reforming processes. These findings emphasize the importance of using nitrogen doping and controlled temperature under atmospheric conditions to maximize the efficiency and product quality of bamboo waste pyrolysis. The results provide valuable insights into sustainable biomass conversion strategies, contributing to the development of renewable energy and increasing the value of bamboo waste.
