Abstract

Biomass pyrolysis is a thermochemical process that converts waste into fuel. The use of zeolite catalysts can enhance efficiency by accelerating biomass decomposition. To demonstrate its effect, thermal simulations were conducted using ANSYS Thermal Transient to analyze temperature distribution, reaction rates, and catalyst effectiveness in the pyrolysis process. This study aims to improve thermal efficiency and temperature uniformity by analyzing the effect of 10% and 20% zeolite mixtures on heat distribution and heating rates at input temperatures of 650 K, 750 K, and 850 K, using the 2D axial symmetry method. The simulation was performed under specific boundary conditions: input temperature on the right, insulation at the bottom, and output applied at the top for 90 minutes. The results showed temperature differences between the 10% and 20% zeolite mixtures. In the 10% zeolite mixture, the temperature at 90 minutes reached 479.83 K at 650 K input, 531.64 K at 750 K, and 583.38 K at 850 K. Meanwhile, the 20% zeolite mixture reached 490.45 K at 650 K, 545.23 K at 750 K, and 599.92 K at 850 K. This confirms that adding zeolite increases thermal conductivity and speeds up heat distribution. The 20% zeolite mixture provided better results with faster heating times and more uniform heat distribution, improving energy efficiency and producing higher-quality pyrolysis products with more stable heat distribution.
