Tert-butyl hydroperoxide (TBHP) as a diesel additive
The present invention relates to the use of TBHP as a fuel additive and in particular as an additive to diesel fuel.
1. A fuel comprising anhydrous tert-butyl hydroperoxide (TBHP) as an additive, wherein the additive comprises TBHP in tert-butanol.
2. The fuel of claim 1 , wherein the additive comprises from 30 to 70 wt % TBHP in from 70 to 30 wt % organic solvent.
3. The fuel of claim 1 , wherein TBHP is present in an amount of from 0.001 wt % to 10 wt % based on the total weight of the fuel.
4. The fuel of claim 1 , wherein the fuel is selected from the group consisting of diesel fuel, petrol, rape methyl ester, kerosine and rocket propellants.
5. The fuel of claim 1 , wherein the fuel is diesel fuel.
6. The fuel of claim 1 , wherein the fuel comprises di-tert-butyl peroxide as a further additive.
7. A fuel additive comprising anhydrous tert-butyl hydroperoxide (TBHP) in tert-butanol.
8. The fuel additive of claim 7 , further comprising di-tert-butyl peroxide (DTBP).
9. The fuel additive of claim 7 , further comprising 2-ethylhexyl nitrate (2-EHN).
10. A method of increasing cetane number of a fuel, comprising adding to the fuel an additive comprising anhydrous tert-butyl hydroperoxide (TBHP) in tert-butanol to increase the cetane number.
11. The method of claim 10 , wherein the additive comprises a mixture of anhydrous TBHP and di-tert-butyl peroxide (DTBP).
12. A method of reducing carbon monoxide emission, hydrocarbon emission or both of a vehicle, comprising running the vehicle on a fuel comprising an additive comprising anhydrous tert-butyl hydroperoxide (TBHP) in tert-butanol.
13. The method of claim 12 , wherein the additive comprises a mixture of anhydrous TBHP and di-tert-butyl peroxide (DTBP).
