SECONDARY-ORIGIN DISTILLATE PROCESSING METHOD Russian patent published in 2008 - IPC C10G59/06

Abstract RU 2316580 C1

FIELD: petroleum processing.

SUBSTANCE: invention, in particular, relates to a method for processing secondary-origin distillates mixed with straight-run fraction in presence of hydrogen and catalysts in two steps with intermediate heating of gas product mixture provided that first-step process is conducted at hydrogen/feedstock ratio 100-120 nm³/m³ for mixture with iodine number up to 40 g I₂/100 g product, 100-170 nm³/m³ for mixture with iodine number to 40-60 g I₂/100 g product, and 170-230 nm³/m³ for mixture with iodine number up to 60 g I₂/100 g product, while second-step process is conducted at hydrogen/feedstock ratio 150-300 nm³/m³. Mixture comprises secondary distillates at their ratio to straight-run fraction (5-95):(95-5). First-step catalyst is preferably alumino-nickel-molybdenum(tungsten).

EFFECT: enhanced process efficiency.
