Abstract
Production of specification diesel fuels from Athabasca oil sands may be achieved by additional input of hydrogen to saturate excessive aromatic concentrations in middle distillates. Hydroprocessing of syncrude distillates from fluid coked Athabasca bitumen was carried out over a sulfided nickel-tungsten catalyst using semi-pilot plant hydrotreaters. Severe hydrotreating pressures were used to generate a series of fuel products over a wide temperature range. Compositional analyses of feedstock and products were performed using low resolution mass spectrometry. Aromatic carbon content was determined by Ca 3 NMR. By this means the effect of hydroprocessing temperature and LHSV on aromatics conversion was monitored. Differences in reactivity including the effects of thermodynamic equilibria and cracking were observed for various aromatic le species. Engine tests performed provided the relationship between the aromatic content and the cetane rating of the products obtained. Some data previously published for distillates from delayed coking are included for comparison.
