Water-Zeolite Interfaces for Controlling Reaction Routes in Fischer-Tropsch Synthesis of Alternative Fuels

摘要

Background:The Fischer-Tropsch Synthesis(FTS)remains an important process for motor fuel production from CO and H2.The composition of the FTS products(hydrocarbon mixtures)depends on the properties of a catalyst and on the process conditions.Summary:The introduction of zeolites into catalytic systems can alter the molecular weight distribution paving the way to tailor-made fuels,as was revealed by recent research results produced in the laboratories worldwide.The AlO4 and SiO4 tetrahedrons,which constitute the zeolites,are able to transfer electrons and ions in a way,which makes water-zeolite interfaces capable of initiating active car-bonium ions.It was shown in a number of works that the water-zeolite interface plays a key role in diverting the FTS from the classical route.Conclusion:This review gives a critical analysis of literature data on the role of water-zeolite interfaces on FTS cobalt catalysts and on the interactions of hydrophobic and hydrophilic zeolites with water.
