Abstract
This document relates to a fuel oil composition comprising: (i) a solid hydrocarbonaceous and/or solid carbonaceous material, wherein the material is in particulate form, and wherein at least about 90% by volume (% v) of the particles are no greater than about 20 microns in diameter; and (ii) a liquid fuel oil; wherein the solid hydrocarbonaceous and/or solid carbonaceous material is present in an amount of at most about 30 by mass (% m) based on the total mass of the fuel oil composition. The invention further relates a process for the preparation of this fuel oil composition, a method of changing a grade of a liquid fuel oil, and a method for adjusting the flash point of a liquid fuel oil.
Claims32
A process for the preparation of a fuel oil composition comprising combining a particulate material, wherein at least about 90% v of the particles within the material are no greater than about 20 microns in diameter;
- and a liquid fuel oil, wherein the particulate material is present in an amount of at most about 30% m based on the total mass of the fuel oil composition;
- wherein the particulate material comprises coal, wherein the coal comprises sedimentary mineral-derived solid carbonaceous material selected from hard coal, anthracite, bituminous coal, sub-bituminous coal, brown coal, lignite or combinations thereof;
- wherein the particulate material comprises less than 5% m of ash content, wherein the liquid fuel oil is selected from one of the group consisting of:
- marine diesel;
- diesel for stationary applications;
- kerosene for stationary applications;
- marine bunker oil;
- residual fuel oil;
- and heavy fuel oil, and wherein the total water content of the fuel oil composition is less than 2% m.
A method for changing the grade of a liquid fuel oil comprising adding to the fuel oil a particulate material, wherein the material is in particulate form, and wherein at least about 90% v of the particles are no greater than about 20 microns in diameter, wherein the particulate material comprises coal, wherein the coal comprises sedimentary mineral-derived solid carbonaceous material selected from hard coal, microfine coal, anthracite, bituminous coal, sub-bituminous coal, brown coal, lignite or combinations thereof;
- wherein the particulate material comprises less than 5% m of ash content, and wherein the liquid fuel oil is selected from one of the group consisting of:
- marine diesel;
- diesel for stationary applications;
- kerosene for stationary applications;
- marine bunker oil;
- residual fuel oil;
- and heavy fuel oil, and wherein the total water content of a mixture of the liquid fuel oil and the particulate material is less than 2% m.
A method of adjusting the flash point of a liquid fuel oil, wherein the method comprises combining a liquid fuel oil with particulate material, wherein the fuel oil is selected from the group consisting of:
- marine diesel;
- diesel for stationary applications, kerosene for stationary applications, marine bunker oil;
- residual fuel oil;
- and heavy fuel oil wherein at least about 90% v of the particles within the material are no greater than about 20 microns in diameter, wherein the particulate material comprises coal, wherein the coal comprises sedimentary mineral-derived solid carbonaceous material selected from hard coal, microfine coal, anthracite, bituminous coal, sub-bituminous coal, brown coal, lignite or combinations thereof;
- and wherein the particulate material comprises less than 5% m of ash content, wherein the total water content of a mixture of the liquid fuel oil and the particulate material is less than 2% m.
A process for the preparation of a fuel oil composition comprising:

- marine diesel;
- diesel for stationary applications;
- kerosene for stationary applications;
- marine bunker oil;
- residual fuel oil;
- and heavy fuel oil;
- and wherein the particulate material comprises coal, wherein the particulate material comprises less than 5% m of ash content, and wherein the total water content of the fuel oil composition is less than 2% m.
