Platiforming Catalyst SPR-1,SPR-2 are the new generation of fixed bed semi-regeneration catalytic reforming catalysts with Platinum as active component and Re as promoter. Catalyst SPR-1,SPR-2 adopt different Re & Pt ratio (Re & Pt in equal ratio or low Re & Pt ratio) respectively. It can improve the stability of the catalyst by improving the relative content of Re. their catalytic performance has reached or exceeded the same kinds of advanced catalysts worldwide. The platiforming series catalysts have been successfully applied in several industrial companies.
