- GASOLINE PREPARED FROM BIOMASS-DERIVED LEVULINIC ACID
-
The present invention provides methods for preparing a C6-C10 alkane, and mixture thereof. The methods include forming a reaction mixture containing an angelica lactone dimer, a catalyst, and a hydrogen source under conditions sufficient to reduce the angelica lactone dimer, thereby preparing the alkane. The methods can be used to prepare branched alkanes useful for fuels. Methods for preparing an angelica lactone, methods for preparing an angelica lactone dimer, and methods for reducing a lactone to an alkane are also described.

- Alkene oligomerization process
-
A process for oligomerising alkenes having from 3 to 6 carbon atoms which comprises contacting a feedstock comprising a) one or several alkenes having x carbon atoms, and, b) optionally, one or several alkenes having y carbon atoms, x and y being different, with a catalyst containing a zeolite of the MFS structure type, under conditions to obtain selectively oligomeric product containing predominant amounts of certain oligomers. The process is carried out at a temperature comprised between 125 and 175° C. when the feedstock contains only alkenes with 3 carbon atoms and between 140 and 240° C., preferably between 140 and 200° C. when the feedstock contains comprises at least one alkene with 4 or more carbon atoms.
