(31b) Dry Reforming (CO2) of Propane and Higher Hydrocarbons for Sustainable Hydrogen Production

The increasing global demand for sustainable energy and the need for effective utilization of greenhouse gases have intensified research into dry reforming processes (Utilization of CO2 as a feed). Dry reforming of propane and higher hydrocarbons (C3+) produces synthesis gas (syngas) which is a mixture of hydrogen (H₂) and carbon monoxide (CO) using carbon dioxide (CO₂) as a reactant. The process offers dual benefits: the conversion of light and heavy hydrocarbons into valuable syngas, and the reduction of CO₂ emissions through utilization.

The study focuses on the thermodynamic, kinetic, and catalytic aspects of the dry reforming process. Nickel-based catalysts, enhanced with promoters and supported on metal oxides, are evaluated due to their cost-effectiveness and activity. However, challenges such as catalyst deactivation due to carbon deposition (coking) and sintering are analyzed. The effect of reaction temperature, pressure, and CO₂ to hydrocarbon molar ratio on product distribution is systematically explored, with a particular emphasis on optimizing H₂/CO ratios for downstream applications like Fischer-Tropsch synthesis and hydrogen production. The findings contribute to advancing sustainable industrial processes by efficiently transforming hydrocarbons and CO₂ into valuable energy resources while reducing environmental impact.

This research provides insights into the potential of dry reforming as a viable technology for energy production and CO₂ mitigation, paving the way for future developments in low-carbon fuel generation and green chemistry applications.
