Abstract:

Based on the processing cost, noble metal cost, noble metals recovery and catalyst life, the technical and economic analysis for the whole life cycle continuous reforming catalyst (from fresh catalyst to catalyst replacement) is conducted. The results show that these factors have a direct impact on the technical and economic indexes of the catalysts. Among of these factors, the life of catalyst is the most critical factor. The initial specific surface area and hydrothermal stability are the decisive factors affecting the service life of catalyst.

Key words: continuous catalytic reforming, catalyst, life cycle, specific surface area, noble metal
