Development and Application of the Current Situation and Development Trend of Platinum-Rhenium Reforming Catalyst

Abstract

This is an essay in the field of ceramics and composites.With the increasing demand for crude oil processing technology, China′s platinum rhenium catalyst industry is also developing. Catalyst is the core material of petroleum smelting, and impregnation method is the most important preparation method of reforming catalyst. Catalytic reforming catalysts generally refer to trace rhenium catalysts. The main research direction in the future is to increase the rhenium content of the catalyst and reduce the amount of platinum in the catalyst. The characteristics of platinum-rhenium catalysts are good stability, slightly poor selectivity, long-term stable operation, and regeneration cycle that can reach 3~5 years, which have been widely used in large-scale production of semi-regenerative reforming processes. Since the late 20th century, China′s refining catalyst market has formed a′Sinopec and PetroChina′s catalyst companies, supplemented by private catalyst companies′ market structure, catalyst demand is stable at more than 10 tons per year.
