Abstract
The production of hydrogen and synthesis gas from hydrocarbon feedstocks is a priority task for the petrochemical and energy sectors due to the increasing demand for clean and versatile energy carriers. Conventional steam reforming processes based on nickel catalysts are widely used for hydrogen and synthesis gas production; however, their practical application is complicated by catalyst deactivation caused by coke deposition, sintering of the active component, and poisoning by sulfur-containing compounds. These limitations require extensive purification of hydrocarbon feedstocks and increase the operating and technological costs of reforming processes. Therefore, the development of efficient and economically viable catalysts capable of maintaining high activity and stability under severe reaction conditions is of significant scientific and practical interest. Particular attention can be given to catalysts supported on natural mineral materials, including vermiculite and vermiculite ore, as well as modified alumina-based systems. The use of such supports may improve the dispersion and stabilization of nickel-containing active components, enhance the thermal and mechanical stability of the catalyst, and provide favorable structural characteristics for reforming reactions. The present study focuses on the development and evaluation of nickel-based catalytic systems for the steam reforming of hydrocarbon feedstocks, including heavy oil residues, petroleum pitch, and resin-containing materials.
