Background: This study compares catalytic reforming technologies, focusing on fixed-bed reforming and continuous catalyst regeneration (CCR) reforming. Fixed-bed systems offer simpler process configurations and lower operational and maintenance requirements, making them a more cost-effective option. Their ability to extend catalyst life by minimizing the frequency of regeneration and replacement represents a notable economic advantage. In contrast, CCR reforming delivers higher processing efficiency and improved product quality but demands greater operating expenditures and more advanced catalyst control systems. Aim: The study evaluates the effectiveness of different catalytic reforming technologies – fixed-bed and CCR – in terms of their impact on process stability, product quality, feedstock and product composition, as well as their potential to enhance the productivity and operational resilience of Kazakhstan’s refineries amid the ongoing development of the national petrochemical sector. Materials and methods: Comparative analysis, gas chromatography, spectroscopy, component and group analysis, fractional composition determination. Results: The analysis of feedstock used in fixed-bed catalytic reforming demonstrated stable process performance, which contributed to improved predictability of reforming unit operations. The presence of iso-paraffins in the feedstock enhanced the quality of high-octane gasoline, while the increased content of naphthenes and aromatic hydrocarbons in the reformate indicated more efficient conversion of heavy fractions. Conclusion: The analysis confirmed that both fixed-bed and CCR reforming technologies continue to evolve, enabling the production of high-quality end products and ensuring stable refinery operations, thereby contributing to the development of Kazakhstan’s petrochemical industry.
