Characterization of nickel and vanadium compounds in tar sand bitumen by petroporphyrin quantitation and size exclusion chromatography coupled with element specific detection | 1988-02 | Previously, 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 ... | |

Study of gas evolution during oil shale pyrolysis by TQMS | 1988-02 | gas evolution; oil shale pyrolysis; TQMS; oil shale; evolution profiles | Real-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... |
