Low emissions diesel fuel

摘要

A low emission diesel fuel suitable for use in underground diesel-engined mining equipment comprises a straight run distillate fuel having an end point not greater than 300 DEG C. (about 660 DEG F.), a cetane number in the range of 55 to 60 a specific gravity not greater than 0.83 a sulfur content not greater than 0.1 wt percent and an aromatics content of 18 to 30 wt. percent. The T90 of the fuels is typically in the range of 255 DEG to 270 DEG C. (about 490 DEG F. to 525 DEG F.), with an initial boiling points typically in the range of 170 DEG to 190 DEG C. (about 340 DEG to 374 DEG F). Ten percent points (T10) are typically in the range from about 200 DEG to 220 DEG C. (about 390 DEG to 430 DEG F.). The API gravity of the fuel is at least 38 and is typically in the range of 38 to 42 and the specific gravity is typically in the range of 0.82 to 0.83.
