aybe this will help you understand how a catalyst functions in a complex chemical environment.
Reforming Catalysts
In petroleum refineries, catalytic reforming is one of the most commonly used processes. During reforming the octane number of naphtha, a raw mixture of hydrocarbons, is increased b dehydrogenation, isomerization, dehydrocycliczation and hydrocracking reactions to make it suitable for gasoline blending and manufacturing of other petrochemical materials. Worldwide, naphtha is processed at a rate of 13 million barrels per day, and reformed naphtha constitutes about 30-35% of the total gasoline pool.
Current reforming catalysts are all platinum (Pt) based, and are usually found in bimetallic formulations with either tin (Sn) or rhenium (Re). The quality of the final naphtha product is very sensitive to catalyst structure since several different chemical reactions occur at distinct catalytically active sites. Using NxCat’s adaptable technology, Headwaters Technology Innovation Group has created a unique competitive advantage by designing a reforming catalyst with superior control of the size, composition and morphology of the nanoparticles. This maximizes the yield of the desired products, increases the lifetime of the catalyst, while limiting unfavorable reactions such as hydrogenolysis and coking.
