- Abstract
Objective Increase the production of naphtha and increase economic benefits. Methods The 1. 8 Mt/a gasoline and diesel oil upgrading unit of PetroChina Yunnan Petrochemical Company Limited was upgraded and transformed, the hydrofining reactor and the cracking reactor has been exchanged, the refining catalyst FF-36A used for first-cycle was regenerated, and new refining catalyst FF-66 and cracking catalyst FC-52 were added. Results Under the condition of 98. 3% load operation, the density of diesel products under 20 t was 839. 5 kg/m³, the cetane index was 40. 3, the sulfur mass fraction was less than 1 µg/g, the polycyclic aromatic hydrocarbons mass fraction was 1.3%, and the diesel products was used for China VI standard in diesel blending. The naphtha yield was 20. 4 wt%, the naphtha final boiling point was 170. 4 t, the sulfur mass fraction was less than 0.5 µg/g, the aromatic latent content was 47. 16 wt%, which is high quality materials for catalytic reforming. Conclusions After upgraded and transformed, the unit reaches the objective of producing high quality naphtha and the economic benefits of the refinery is improved.
