Oily biofuel suspension and method for manufacturing same

Abstract

The present invention is related to biofuel oily suspensions that use biocarbon in their composition. In this scenario, the present invention provides a biofuel oily suspension, comprising 5 to 50% by weight of micronized biocarbon and 50 to 95% by weight of oil. The biofuel oily suspension of the present invention is better adapted to compression internal combustion engines (diesel type) currently on the market, dispensing with major adaptations to them. Furthermore, the biofuel oily suspension of the present invention is highly sustainable and has an energy volumetric density and viscosity compared to liquid fossil fuels currently on the market.

1 . Biofuel oily suspension, characterized by understand:
 5 to 50% by mass of micronized biocarbon; and   50 to 95% by mass of liquid suspension base; and   wherein the biocarbon has a bimodal particle size distribution and contains low ash content.   
     
     
         2 . Biofuel oily suspension according to  claim 1 , characterized in that the liquid base of the suspension is at least one of:
 bunker oil;   marine diesel oil or gas oil;   hydrotreated vegetable oil;   hydrotreated pyrolysis oil; and   vegetable tar.   
     
     
         3 . Biofuel oily suspension according to  claim 2 , characterized by comprising:
 5 to 50% by mass of micronized biocarbon;   50 to 95% by mass of bunker oil; and   0 to 30% by mass of marine diesel oil.   
     
     
         4 . Biofuel oily suspension according to  claim 2 , characterized by comprising:
 5 to 50% by mass of micronized biocarbon;   50 to 95% by mass of hydrotreated vegetable oil; and   0 to 50% by weight of vegetable tar.   
     
     
         5 . Biofuel oily suspension according to  claim 2 , characterized in that it comprises:
 5 to 50% by mass of micronized charcoal; and   50 to 95% by mass of hydrotreated pyrolysis oil.   
     
     
         6 . Process of manufacturing of a biofuel oily suspension, comprising the steps of:
 micronize biocarbon to a maximum diameter of 50 μm; characterized by also comprising:   mix 5 to 50% by weight of micronized biocarbon to 50 to 95% by weight of liquid suspension base; and   where the biocarbon has a bimodal particle size distribution and is produced from eucalyptus biomass.   
     
     
         7 . Process according to  claim 6 , characterized in that the liquid base of the suspension is at least one of:
 bunker oil;   marine diesel oil;   hydrotreated vegetable oil;   hydrotreated pyrolysis oil; and   vegetable tar.   
     
     
         8 . Process according to  claim 6 , characterized by additionally comprising a step of adding at least one surface-active additive to the biofuel oily suspension. 
     
     
         9 . Process according to  claim 6 , characterized in that  eucalyptus  biomass is barkless.
