Abstract
The invention provides a process for the production of a fully synthetic heavy fuel oil, said process including at least fractionation of hydrocarbons obtained from the hydroconversion of C5 and heavier Fischer-Tropsch (FT) process products to obtain a product that is heavier than a middle distillate and has an ASTM D86 cut-off temperature in excess of 350° C. Further, the invention provides a fuel made in accordance with the process.
Claims17
A synthetic heavy fuel oil comprising:
- less than 100 ppm sulfur;
- at least 90 wt. % of linear paraffins that are heavier than C19;
- and
- less than 2 mass % aromatics,
- wherein the synthetic heavy fuel oil has a density of more than 0.800 g·cm3 (at 20° C.), a kinematic viscosity of greater than 8 mm2/s (at 50° C.) and less than 20 mm2/s (at 50° C.), and a pour point of at least 12° C. and less than 25° C.
