Abstract
Pyrolysis technology relies on efficient catalyst materials to expedite the process and improve the quality of the final product. Modified natural zeolite has emerged as a promising heterogeneous catalyst in this regard. This study presents a comprehensive analysis of natural zeolite sourced from Tasikmalaya, West Java, with the primary aim of evaluating its potential as a catalyst. The samples underwent acid treatment procedures and were extensively characterized using BET, TGA, SEM-EDX, X-Ray Diffraction (XRD), and FT-IR tests. XRD results indicated that the predominant frame structure of the Indonesian raw natural zeolite was mordenite, with a Si/Al ratio ranging from 5.0 to 6.0 and a surface area of approximately 23 m²/g. Following the 1M HCl acid treatment, a significant enhancement in the Si/Al ratio to 7.8 and a considerable expansion in surface area to 125.37 m²/g were observed. Moreover, the natural zeolite demonstrated remarkable thermal stability, thus underscoring its potential as a highly suitable catalyst for various pyrolysis applications.
