Abstract
The present invention provides fuels for combustion engines of the diesel type and petrol type and especially to fuels having an increased content of fuel components originating from renewable sources. In particular, diesel type fuels are provided, which contain at least solketal, renewable alkane fuel and biodiesel. Petrol fuels are also provided, wherein solketal is provided as a substitute for fossil petrol or other petrol fuel components. The present invention further provides methods for manufacturing the fuels of the invention as well as uses thereof.
Claims18
A diesel fuel composition comprising:
- (a) solketal;
- (b) biodiesel;
- (c) optionally renewable alkane;
- (d) optionally fossil diesel;
- and
- (e) optionally one or more further additives;
- wherein
- the relative amount of solketal, w(a), is 0.1 to 32 weight-%,
- the relative amount of biodiesel, w(b), is 2 to 95 weight %, such as 2 to 85 weight-%,
- the relative amount of renewable alkane, w(c), is 0 to 97 weight-%, such as 0.1 to 97 weight-%,
- the relative amount of fossil fuel, w(d), is 0 to 50 weight-%, and
- the relative amount of total additives, w(e), is 0 to 10 weight-%,
- all weight-% indications being based on the total weight of the composition, wherein the relative amount of solketal, biodiesel, renewable alkane and the relative amount of fossil fuel are optionally selected such that at least one of following equations is fulfilled:
