First claim

1 - 15 . (canceled)

16 . A method for upgrading carbohydrates, carbohydrate derivatives or lignocellulosic material, the method comprising:
providing a feedstock containing carbohydrates, carbohydrate derivatives or lignocellulosic material, wherein the lignocellulosic material, carbohydrates or carbohydrate material includes angelica lactone; and dimerising and/or oligomerising the carbohydrates, carbohydrate derivatives or lignocellulosic material in a presence of a heterogeneous catalyst to produce a dimer and/or oligomer; wherein oligomerising constitutes formation of trimers or higher; wherein the lignocellulosic material is levulinic acid, an ester of levulinic acid and/or a dehydration product of levulinic acid; and wherein the heterogeneous catalyst is an inorganic catalyst containing an alkali metal compound and/or an alkaline earth metal compound and at least one further metal compound.

17 . The method according to claim 16 , wherein the heterogeneous catalyst is a supported catalyst.

18 . The method according to claim 17 , wherein the heterogeneous catalyst is a catalyst comprising:
the alkali metal compound and/or the alkaline earth metal compound on a support formed by the further metal compound.

19 . The method according to claim 18 , wherein the support is formed by an oxide of the further metal.

20 . The method according to claim 17 , wherein the heterogeneous catalyst is a catalyst comprising:
an oxide of the alkali metal and/or an oxide of the alkaline earth metal on a support formed by an oxide of the further metal.

21 . The method according to claim 16 , wherein the heterogeneous catalyst is a catalyst comprising:
the alkali metal compound and/or the alkaline earth metal compound as a mixed compound.

22 . The method according to claim 21 , wherein all compounds of the catalyst are in oxide form.

23 . The method according to claim 16 , wherein a metal constituting the alkali metal compound and/or an alkaline earth metal compound is at least one selected from the group consisting of Li, Na, K, Mg and Ca.

24 . The method according to claim 20 , wherein the metal constituting the alkali metal compound and/or an alkaline earth metal compound is at least one selected from the group consisting of Li, Na, K, Mg and Ca.

25 . The method according to claim 16 , wherein the further metal constituting the further metal compound is at least one selected from the group consisting of Al, Si, Sc, Ti, V, Y, Zr, Nb, Mo, La, Ce, Hf, Ta and W.

26 . The method according to claim 23 , wherein the further metal constituting the further metal compound is at least one selected from the group consisting of Al, Si, Sc, Ti, V, Y, Zr, Nb, Mo, La, Ce, Hf, Ta and W.

27 . The method according to claim 24 , wherein the further metal constituting the further metal compound is at least one selected from the group consisting of Al, Si, Sc, Ti, V, Y, Zr, Nb, Mo, La, Ce, Hf, Ta and W.

28 . The method according to claim 16 , wherein the further metal constituting the further metal compound is at least one selected from the group consisting of Al, Si, Ti, Zr and Ce.

29 . The method according to claim 23 , wherein the further metal constituting the further metal compound is at least one selected from the group consisting of Al, Si, Ti, Zr and Ce.

30 . The method according to claim 24 , wherein the further metal constituting the further metal compound is at least one selected from the group consisting of Al, Si, Ti, Zr and Ce.

31 . The method according to claim 16 , wherein the heterogeneous catalyst is selected from the group consisting of NaOx/ALOx; KOx/ALOx; MgOx/AlOx; NaOx/SiOx; KOx/SiOx; MgOx/SiOx; NaOx/TiOx; KOx/TiOx; MgOx/TiOx; NaOx/CeOx; KOx/CeOx; MgOx/CeOx; NaOx/ZrOx; KOx/ZrOx; MgOx/ZrOx;
wherein the term “Ox” refers to an oxide of a respective metal and a sign “I” refers to providing respective compounds as a supported catalyst, including being the support, or a mixed compound catalyst.

32 . The method according to claim 31 , wherein the heterogeneous catalyst is selected from the group consisting of KOx/TiOx and MgOx/ZrOx.

33 . The method according to claim 16 , wherein the heterogeneous catalyst comprises:
