The liquid fuel consists of a light oil component consisting of C6-C12 alkane, a catalytic component consisting of C13-C16 alkane, and a heavy oil component. On the basis of the liquid fuel, the mass fraction of the heavy oil component is 10%-90%, the mass fraction of the light oil component is 0-49%, and the mass of the catalytic component accounts for 86% or more of the mass of the light oil component; and the liquid fuel may also contain an aromatic hydrocarbon having a mass fraction of 0-15%. The obtained liquid fuel has good driving performance, combustion performance and safety, and can be applied to a diesel engine system, a diesel/heavy oil combustion system, etc., as a mixed fuel oil. ## Claims ### Claim 1 A liquid fuel comprises light oil component composed of C6-C12 alkanes, catalytic component composed of C13-C16 alkanes, and heavy oil component; On the basis of the liquid fuel, the mass fraction of the heavy oil component is 10%-90%, the mass fraction of the light oil component is 0%-49%, the mass fraction of the catalytic component is 10%-90%, and the mass of the catalytic component accounts for 86% or more of the mass of the light oil component; and the liquid fuel may also contain an aromatic hydrocarbon having a mass fraction of 0%15%. ### Claim 2 (depends on 1) The liquid fuel according to claim 1, wherein the mass content of the heavy oil component is 30%-90% based on total mass of the liquid fuel. ### Claim 3 (depends on 1) The liquid fuel according to claim 1, wherein the mass content of the light oil component is 5%-49% based on total mass of the liquid fuel. ### Claim 4 (depends on 1) The liquid fuel according to claim 1, wherein the closed cup flash point of the light oil component mixed with the catalytic component is not lower than 47° C. ### Claim 5 (depends on 1) The liquid fuel according to claim 1, wherein the closed cup flash point of the liquid fuel is not lower than 48° C. ### Claim 6 (depends on 5) The liquid fuel according to claim 5, wherein the closed cup flash point of the liquid fuel is not less than 55° C. ### Claim 7 (depends on 1) The liquid fuel according to claim 1, wherein the mass of the catalytic component accounts for 86%-1000% of the mass of the light oil component. ### Claim 8 (depends on 7) The liquid fuel according to claim 7, wherein the mass of the catalytic component accounts for 86%-500% of the mass of the light oil component. ### Claim 9 (depends on 8) The liquid fuel according to claim 8, wherein the mass of the catalytic component accounts for 100%-500% of the mass of the light oil component. ### Claim 10 (depends on 9) The liquid fuel according to claim 9, wherein the mass of the catalytic component accounts for 300%-500% of the mass of the light oil component. ### Claim 11 (depends on 1) The liquid fuel according to claim 1, wherein the heavy oil component includes waste engine oil, biodiesel, biological oil and its derivatives or a combination of two or more. ### Claim 12 (depends on 11) The liquid fuel according to claim 11, wherein the biological oil and its derivatives include animal or plant oil and its derivatives, and/or restaurant waste oil. ### Claim 13 (depends on 1) The liquid fuel according to claim 1, wherein the light oil component composed of alkanes of C6-C12 comprises a single alkane with 6-12 carbons or a mixture of more than one of them. ### Claim 14 (depends on 13) The liquid fuel according to claim 13, wherein the light oil component composed of alkanes of C6-C12 comprises one or more of normal alkanes with 6-12 carbons and isoalkanes with 6-12 carbons and cycloalkanes with 6-12 carbons. ### Claim 15 (depends on 1) The liquid fuel according to claim 1, wherein the catalytic component composed of alkanes of C13-C16 comprises a single alkane with 13-16 carbons or a mixture of more than one of them. ### Claim 16 (depends on 15) The liquid fuel according to claim 15, wherein the catalytic component composed of alkanes of C13-C16 comprises one or more of normal alkanes with 13-16 carbons and isoalkanes with 13-16 carbons and cycloalkanes with 13-16 carbons. ### Claim 17 (depends on 1) The use of liquid fuel as diesel engine fuel according to claim 1; wherein the liquid fuel has a cetane number of more than 40, which is used as a high-speed diesel engine fuel; the cetane number of the liquid fuel is more than 30, which is used as a medium-speed diesel engine fuel; or, the cetane number of the liquid fuel is lower than 30, which is used for the low-speed diesel engine fuel. ### Claim 18 (depends on 1) The use of the liquid fuel described in claim 1 as fuel for diesel/heavy oil combustion system, and as an alternative fuel to aviation jet turbine fuel, vehicle diesel or aviation kerosene.
