Correlation of Chemical Characteristics with Fuel Properties by Gas Chromatography.
Abstract
Standard tests such as those published in ASTM are used to determine a fuel's properties. As new fuels are introduced, it becomes necessary to characterize them by applying available standard test methods and chemical/physical characterization techniques in a process which is costly, time consuming and developmental by its very nature. Because of the technical advances in digital computers and gas chromatography, it has become feasible to attempt to develop correlations between gas chromatographic data and some chemical/physical properties. These, it turn, may be related to a fuel's performance. Eight test fuels were selected for this preliminary work because of their known stability and chemical/physical properties. A modified ASTM D 2887 boiling point distribution (BPD) method was developed to yield component specific identification in addition to BPD consistant with the conventional D 2887 method. The data from this modified method may be used in correlation equations to automatically calculate Reid Vapor Pressure, ASTM D 86, ASTM D 1160, API gravity, flash point, viscosity, and freeze point. In addition, the capability to 'profile' several chromatograms for direct visual comparison has been developed and added to the system. Other analytical techniques, such as NMR, were evaluated for their possible contribution to this correlation development. (Author)
