    摘要： The present invention discloses a valorisation method of a flux containing undesired D-lactic acid (ester(s)) in the production process of L-polylactic acid, the production thereof comprising: oligomerisation (30) of a substantially pure L-lactic acid feed; cyclisation (40) of the lactic acid oligomers, thereby obtaining lactides and a first residual stream transferred, at least partially, to a transesterification (80) and a hydrolysis (90) step; lactide purification (50), thereby obtaining purified lactides comprising L-lactide and meso-lactide, a second and a third residual stream, wherein the second residual stream is transferred, at least partially, to the oligomerisation (30) step and the third residual stream is transferred, at least partially, to a transesterification (80) and a hydrolysis step (90); polymerisation (60) of the purified lactides into polylactic acid; purification (70) of the polylactic acid, thereby obtaining purified polylactic acid comprising substantially L-polylactic acid and unreacted L-lactide, unreacted meso-lactide and impurities transferred, at least partially, to the lactide purification step (50); transesterification (80) and hydrolysis (90) of the at least partially transferred first and third residual streams, thereby obtaining a fourth and a fifth residual stream which are used, at least partially, as a base for the synthesis of molecules insensitive to the optical isometry D or L of lactic acid (esters).

    摘要： Processes for fatty acid ketonization and alcohol dehydration, wherein an alumina catalyst disposed in, or removed from, a reaction zone may be regenerated by contacting the catalyst with steam during or after a coke oxidizing step. In an embodiment, such processes may provide C2-C43 alkenes. In another embodiment, such processes may provide C11-C43 ketones, which can be deoxygenated to give saturated hydrocarbons, unsaturated hydrocarbons, and mixtures thereof. Base oils and transportation fuels may be produced via such processes.

    摘要： The present invention relates to a method for producing ketones which method comprises the steps of:
    d) providing a feedstock of biological origin comprising fatty acids and/or fatty acid derivatives having an average chain length of 24 C-atoms or less,
    e) subjecting said feedstock to a catalytic ketonisation reaction,
    f) obtaining from said ketonisation reaction a product stream comprising ketones, which ketones have a longer average hydrocarbon chain length than the average hydrocarbon chain length in said feedstock,
    characterised in that said catalytic ketonisation reaction is carried out in the presence of a K 2 O/TiO 2 -catalyst;
    and use of ketones obtainable according to the method as base oil components or as intermediate material for product of base oil components.
