Description

Marine fuel
Technical field
[0001] This invention is in the field of marine fuels, in particular liquid carbonaceous marine fuels, which are composed mainly of hydrocarbon mixtures.
Background Art
[0002] Several marine fuels that are 50-70% (hereinafter percentage by weight, w/w) mixtures of fuel oil with an additive (30-50% diesel fuel) are commonly known. The problem with such marine fuels is their instability and incomplete combustion. Other mixtures of oil residues and residual fuels with various oil distillates, incl. gas oil and diesel fuel, are also well known.
[0003] One such marine fuel has been described, for instance, in Russian Federation patent RU 2084494 (UFIM G NEFTYANOJ TEKHN UNI) 20.07.1997 , where 50-75% fuel oil has been mixed with additives, which include oil sludge and residual oil (both contributing 12,5-25%) that have been dehydrated in two or three stages.
[0004] Adding depressants in small doses to marine fuels in order to improve their properties is also known. Such a solution has been described, for instance, in Russian Federation patent RU 2154665 (VASIL EV ROSTISLAV L VOVICH) 20.08.2000 , where up to 0.05% of depressant can be added to the marine fuel.
[0005] Russian Federation patent RU 2155211 (EPERERABATYVAJUSHCHIJ ZD; SYZRANSKIJ NEFT AOOT) 27.08.2000 , where fuel oil has been mixed with additives, such as 5-30% long residue, up to 25% oil distillate wide vacuum fracture 260-510 °C or high temperature cracking products of up to 25% long residue, and oil distillate wide vacuum fraction 260- 510 °C, 20-25% light gas oil, 15-40% hydro-fined diesel fuel and up to 0.05% depressant can be regarded as the closest known solution to this invention.
Disclosure of Invention
[0006] International marine fuel standard ISO 8217:1996 permits the content of sulphur 3.5-5.0%, vanadium content 150-600 mg/kg, and aluminium content with silicon up to 80 mg/kg. The allowed pour point is between 0 °C and +30 °C.
[0007] The aim of this invention is to create a marine fuel with a different composition from known solutions on the basis of fuel oil and shale oil products, which would be, due to the small content of sulphur and other harmful additives in shale oil products, more environmentally-friendly (sulphur content in marine fuel 1.7-2.3%, vanadium content 62-114 mg/kg, aluminium content with silicon 18-38 mg/kg, lower heavy metal content), have smaller kinematic viscosity and a lower pour point (from -19 °C to +19 °C) than the standard marine fuels in accordance with ISO 8217:1996. [0008] In order to achieve the aim of this innovation, one or several of the following additives, which are oil shale products, are mixed with fuel oil M- 100 (GOST 10585-99): shale oil fractions 180-230 °C, 230-320 °C and 320-360 °C, shale fuel oil, shale oil marks A and B, refined distillate shale oil D-1 and fuel for small boilers TMK (see Tables 1.1 and 1.2).
