A process for producing a marine fuel or a marine fuel component comprising uncracked asphaltene, and uses and products related thereto Authors: Esko Karvinen, Varpu Markkanen, Eija Koivusalmi, Wolter Rautelin, Riikka- Mari Haara, Christina Jäger Neste Oyj, Technology Center, Teknologiantie 36, 06850 Kulloo, Finland Background of the invention Asphaltenes are defined as the heaviest components of crude oil. Their concentration in the crude oil is dependent on the crude oil origin itself. Asphaltenes are the highest molecular weight molecules in the crude, and contain all of the organically bound vanadium and most of the nickel found in the crude. Asphaltenes are insoluble in light n-alkanes such as n-heptane (nC7) but soluble in aromatics such as toluene. Their hydrogen content (and hence, combustion characteristics) can be quite different from one crude to another. Asphaltenes have predominantly aromatic structures. Precipitation of asphaltenes from a residual fuel oil in the form of sediment can occur during storage and handling. Such sediment can cause severe difficulties, and in extreme cases can render the fuel unfit for use. Aged sediment has long been a limiting factor for residual marine fuels. For example, asphaltenes can be separated by solvent deasphalting (SDA) from residues obtained by distilling crude oil (see e.g. WO2019053323 A1). US9315733 B2 describes a specific application wherein different components of an SDA bottom stream are separated and for example the separated solid asphalt phase and the recovered solid adsorbent material from a solvent deasphalting unit are integrated into an asphalt pool. The asphalt pool can be used, for instance, as paving materials or cutback asphalt. US11384301 B2 describes adding an aromatic rich hydrocarbon fraction, such as decant oil, to stabilize an asphaltenic resid prior to adding distillates as diluents to subsequently drive down the sulfur content to meet low sulfur specifications. The aim is to facilitate initial compatibility and aged stability of asphaltenic resids. Ksenia I. Smyshlyaeva et al. (Asphaltene genesis influence on the low-sulfur residual marine fuel sedimentation stability, Fuel 328 (2022) 125291) describes the results of studies carried out to determine the influence of asphaltene genesis on the low sulfur marine residual fuel sedimentation stability, based on RMG 380 commercial fuel as an example. Fractions rich in asphaltenes from varying origins (vacuum residues, asphalt, visbreaker residues, heavy pyrolysis resins) were studied and analyzed. The dependence of asphaltene genesis influence on stability was assessed by adding the different fractions rich in asphaltenes, in an amount of 1 to 5 wt%, into RMG 380 marine fuel base compositions of constant composition according to “total sediment aged” (TSA) index. In the article the stability of RMG 380 d...
