A marine fuel blend

Abstract

The present invention relates to a marine fuel blend having a kinematic viscosity of 1-700 mm 2 /s as measured at 50° C. according to EN ISO 3104:1996 and comprising 0.5-50 vol-% of refined cashew nut shell liquid, which cashew 5 nut shell liquid comprises at least 50 wt-% of cardanol.

         20 . The marine fuel blend according to  claim 18 , comprising 0.5-10 vol-% of refined cashew nut shell liquid. 
     
     
         21 . The marine fuel blend according to  claim 18 , having an amount of aged sediment of less than 0.08 wt-% as measured by ISO 10307-2:2009. 
     
     
         22 . The marine fuel blend according to  claim 17 , wherein the cashew nut shell liquid comprises at least 80 wt-% of cardanol. 
     
     
         23 . The marine fuel blend according to  claim 17 , wherein the cashew nut shell liquid has been refined by any of vacuum distillation, distillation, heat treatment, filtration, degumming or combinations thereof. 
     
     
         24 . A method for manufacturing a marine fuel blend, the method comprising mixing a refined cashew nut shell liquid comprising at least 50 wt-% of cardanol with a as marine fuel component with at least one of a residual fossil-based component, a co-processed component obtained by co-processing one or more fossil feeds with one or more renewable feeds, and a renewable component, the marine fuel blend having a kinematic viscosity of 31-700 mm 2 /s as measured at 50° C. according to EN ISO 3104:1996, and fulfilling at least one of the categories of ISO 8217:2017(E) for residual marine fuels. 
     
     
         25 . A method for manufacturing a marine fuel according to  claim 17 , having a kinematic viscosity of 31-700 mm 2 /s as measured at 50° C. according to EN ISO 3104:1996, comprising mixing a residual fossil-based component and/or a co-processed component obtained by co-processing one or more fossil feeds with one or more renewable feeds and/or a further renewable component, with 0.5-50 vol-% of refined cashew nut shell liquid, which cashew nut shell liquid comprises at least 50 wt-% of cardanol, the resulting marine fuel fulfilling at least one of the categories of ISO 8217:2017(E) for residual marine fuels.
