Trends of petroleum fuels: Topical report

Trends in properties of motor gasolines for the years 1942 through 1986; diesel fuels for the years 1950 through 1986; aviation fuels for the years 1947 through 1986; and heating oils for the years 1955 through 1986, have been evaluated based upon data contained in surveys prepared and published by the National Institute for Petroleum and Energy Research (NIPER) and its predecessor organizations. The surveys for motor gasolines were conducted under a cooperative agreement with the Coordinating Research Council (CRC) and the Bureau of Mines from 1935 through 1948 and in cooperation with the American Petroleum Institute (API) since 1948 for all surveys. The motor gasoline surveys have been published twice annually since 1935 describing the properties of motor gasolines produced and marketed throughout the country. Other surveys prepared in cooperation with the API and the Bureau of Mines, the Energy Research and Development Administration, the Department of Energy, and currently the National Institute for Petroleum and Energy Research were aviation gasolines beginning in 1947, diesel fuels in 1950, aviation turbine fuels in 1951, and heating oils, formerly burner fuel oils, in 1955. Various companies throughout the country obtain samples of motor gasolines from retail outlets and refinery samples for more » the other surveys, and analyze the samples using American Society for Testing and Materials (ASTM) procedures. The analytical data are sent to the Bartlesville Center for survey preparation and distribution. A summary report has been assembled from data in 87 semiannual surveys for motor gasolines that shows trends throughout the entire era from winter 1942 to 1943 to the present. Trends of diesel fuel properties are shown for type C-B/grade 1-D and type T-T/grade 2-D fuels. Trends for properties of heating oils have been plotted for grades 1, 2, and 6, and for properties of grades JP-4, JP-5, and Jet aviation turbine fuels. 45 refs., 12 figs., 8 tabs. « less
