MODERNIZATION OF OIL REFINING CATALYTIC PROCESSES TO PRODUCE FUELS WITH ENHANCED ENVIRONMENTAL CHARACTERISTICS ON THE BASIS OF EXISTING REFINERY EQUIPMENT

摘要

Requirements for motor fuel characteristics will have changed dramatically by 2005-2007. Hence, construction of new grass-root secondary refining units is necessary, while the existing units have to be modernized substantially, which in turn requires extensive investments. However, there is a far much cheaper option. The philosophy of multifunctional reactors based on novel catalytic systems changes the feedstock conversion chemistry and allows existing refineries to produce fuels and petrochemicals with drastically improved qualities. We have succeeded in using old catalytic cracking and reforming technologies to produce hydrogen and reformulated gasoline (low in aromatics, benzene and olefins). We have also managed to increase the gasoline yield from vacuum gas-oil cracking.
