Description

Marine fuel blend Technical Field The present invention relates to marine fuel (marine fuel) blends and their use. Background Marine fuels are traditionally based on fossil oils and generally have higher viscosities than gasoline and diesel, for example, for land vehicles. However, due to problems associated with pollution and climate change, it is also desirable to provide marine fuels having a lower sulfur content, for example. Another need is to reduce greenhouse gas (GHG) emissions. Indeed, the goal of the International Maritime Organization (IMO) was to reduce international shipping annual GHG emissions by 2050 by at least 50% over the 2008 emissions levels. This objective can be achieved by increasing the efficiency of e.g. the motor and operation, but also the need for alternative fuels. Palm oil sludge (also known as palm oil mill effluent oil (POME oil) or palm oil effluent sludge (PES)) is sludge that is a by-product in the production of palm oil. Today, it is considered a low value waste product, but when it is further processed, the processed product can find other end uses, thereby increasing its value. One treatment of PES is distillation, typically followed by one or more purification treatments. When the objective is to remove free fatty acids, the maximum distillation temperature is typically 260 ℃. Such distillation naturally also results in the removal of volatile organic compounds. Distillation is generally carried out under pressure, for example 3-5 mbar (absolute). Steam stripping is typically used to enhance the removal of free fatty acids. The resulting product includes a palm oil effluent sludge substrate (palm oil effluent sludge bottom), which is therefore the distillation bottoms fraction of the direct distillation of PES crude oil. It may also be referred to as refined palm oil mill effluent (refined POME). The distillation removes free fatty acids from the product, thereby reducing the Total Acid Number (TAN). Document WO 2012/108584 discloses a process for manufacturing an environmentally friendly high viscosity bio-marine oil (biobunker C oil) with low sulphur content. The method uses a process in which palm fruit is first subjected to a temperature treatment, then pressed and refined to produce palm crude oil. This crude palm oil is further refined to produce refined, bleached and deodorized palm oil and palm oil byproducts. The liquid palm oil byproduct is then filtered and completely dissolved by the addition of an organic solvent. Thereafter, water is removed from the dissolved palm oil by-product by contacting the water scavenger with the dissolved palm oil by-product, impurities are removed from the dehydrated palm oil by-product by centrifugation, and the organic solvent is removed, thereby completing the manufacture of the refined palm oil by-product. Finally, the refined palm oil byproduct is mixed with the high viscosity marine oil, thereby completing the manufacture of the high viscosity biological marine oil. The purpose is to provide for the use of palm oil effluent sludge substrate. Another object is to provide alternative marine fuels and marine fuel blends. It is a further object to provide a marine fuel blend having fewer fossil-based components than conventional marine fuels, i.e., providing a marine fuel blend having renewable components therein. Disclosure of Invention According to one aspect, a marine fuel blend is provided having a kinematic viscosity of 2-30 mm 2/s measured at 50 ℃ according to EN ISO 3104:2020 and comprising 0.5-50 vol-% of a palm oil effluent sludge substrate, the marine fuel blend meeting at least one of the categories for marine fuel ISO 8217:2017 (E). According to another aspect, there is provided the use of a marine fuel blend for reducing greenhouse gas emissions. For the blend components in% by volume depending on the components, the reduction in GHG emissions is at least 9% (in CO 2eq/MJ) calculated according to instructions 2018/2001 from the european parliament and the council. According to another aspect, there is provided a method of manufacturing a marine fuel blend having a kinematic viscosity of 2-30 mm 2/s measured at 50 ℃ according to EN ISO 3104:2020, comprising mixing a fossil-based component with 0.5-50 vol-% of a palm oil effluent sludge substrate, the resulting marine fuel blend meeting at least one of the classes of ISO 8217:2017 (E) for marine fuels.

Detailed Description In the present specification, weight percent (wt-%) is calculated based on the total weight of the blend. Volume percent (vol-%) is also calculated based on the total volume of the blend. In the context of renewable fuel components, the term "renewable" refers to one or more organic compounds that are derived from any renewable source (i.e., not derived from any fossil-based source). Thus, renewable fuel components are based on
