  The development of new materials from different waste is one of the biggest areas of technological advancement worldwide, which has grown considerably in recent years. Associated with this is the importance of developing these materials at higher levels of production, so the technology is not only developed, but also disseminated on the global market. In view of this, the development of pilot plants for the production of materials on larger scales is extremely important, as in addition to ensuring the scalability of the material, it serves as a contribution for methodological tests before they are produced on an industrial scale. Several studies have been carried out regarding the synthesis of zeolites from fly ash obtained from coal power plant, which is a promising raw material for obtaining the product. Related to zeolites, mainly type X, studies demonstrate their great potential as an adsorbent in CO₂ capture, for example, and therefore, this work aimed to synthesize zeolite type X from the fly ash in a pilot plant installed at SATC - Beneficent Association of the Santa Catarina Coal Industry, located in Criciúma, Santa Catarina-Brazil. The methodology used was fusion followed by hydrothermal reaction, and the zeolite obtained (XFF-PP1) showed good mineralogical formation, with phases typical of type X zeolites, good chemical composition, surface area of ??713.82 m² and adsorption capacity of 2.30 mmol/g of CO₂, thus validating the process on a pilot scale.
