1 Study of gas evolution during oil shale pyrolysis by TQMS1988-02gas evolution; oil shale pyrolysis; TQMS; oil shale; evolution profilesReal-time gas evolution during pyrolysis of two Green River Formation (Colorado) oil shales, one eastern U.S. Devonian shale, and two Chinese shales was monitored using a triple quadrupole mass spectrometer (TQMS). We calculated kinetic parameters for hydrocarbon generation. For water, carbon oxides...
2 Characterization of nickel and vanadium compounds in tar sand bitumen by petroporphyrin quantitation and size exclusion chromatography coupled with element specific detection1988-02Previously, we have examined the Ni and V in heavy crude oils, residua, and processed products by several metal speciation techniques to ascertain molecular structure and processing behavior. Two classes 01 metal compounds were found -- metallopetroporphyrins and metallo-nonporphyrins - each having ...
