LOW-VISCOSITY MARINE FUEL PRODUCTION PROCESS Russian patent published in 2004 - IPC

Abstract RU 2232793 C1

FIELD: petroleum processing.

SUBSTANCE: process atmospheric-vacuum distillation of petroleum to isolate straight-run and vacuum fractions, catalytic cracking of long vacuum fraction to produce catalytic cracking distillate. Isolated vacuum fraction 360-490^оС is purified with selective solvent and thus obtained high-aromatized extract is then compounded with straight-run fractions and catalytic cracking distillate at ratios between 1:69:30 and 20:25:55, respectively, to produce desired product. Straight-run fractions boiling in the range 160-380^оС are recovered. According to invention, long vacuum fraction subjected to catalytic cracking has boiling range 350-540^оС and catalytic cracking distillate boils within 160 to 420^оС. Invention also envisages completion of desired product with coking process fraction 160-420^оС in amounts up to 50 wt %.

EFFECT: increased yield of desired product and improved physicochemical characteristics of fuel.
