Types segmentation classifies catalysts by active metal and support architecture. The Platinum‑based family, typically 0.1–0.5 % Pt on alumina or zeolite, dominates the market (≈70 % of volume) due to its superior dehydrogenation activity and stability under severe reforming conditions. Within this family, Monometallic Pt and Bifunctional Pt‑Re variants differ in hydrogenation balance and resistance to coke formation. Bifunctional catalysts, combining Pt with a secondary metal such as Re, Ir or Ru, represent roughly 20 % of sales, targeting higher aromatics yields and lower hydrogen consumption. Zeolite‑supported catalysts, especially those employing Y‑ or USY‑type zeolites, account for the remaining 10 % and are selected for their shape‑selective properties that enhance specific aromatics profiles. Each type’s cost structure, performance envelope, and lifespan directly influence the total market size, forming the basis of the Catalytic Reforming Catalyst segmentation market taxonomy.
