RI 3591 Determination Of Types Of Sulfur Compounds In Petroleum Distillates ? Introduction (f17cca9e-1e45-4d75-a351-ad476071484f)

[A system of analysis for sulfur groups in petroleum distillates has been developed as one phase of the Bureau-of Nines investigation of the more economic utilization of the so-called "black oils" of Wyoming,. This problem is being studied by the Bureau of Nines under a cooperative agreement with the University of Wyoming at the Bureau's Petroleum Experiment Station, Laramie, Wyo. Wyoming black oils have high sulfur and asphalt content and usually yield only small percentages of straight-run gasoline. A more detailed description of the properties of black oilshas been given in a previous publication (3)3/. The preparation and properties of asphalts from those oils have been described (1, 2), end the effect of thermal cracking and the use of ordinary methods of treating wore discussed in one Bureau publication (4), Although these studies gave considerable insight into the properties and characteristics of black oil, it was thought t that a more fundamental attack would assist materially in the problem of sulfur removal.]
