Process for making propylene by dehydration of propanol, involving the following steps: o Gasifying carbonaceous solid or liquid feedstock or reforming gaseous carbonaceous feedstock into synthesis gas, o Fermenting the synthesis gas by means of a microorganism into substantially propanol or o Co-Fermenting the synthesis gas with at least one liquid oxygenate by means of a microorganism into substantially propanol in which the microorganism ° Is a wild strain having the natural capability to ferment synthesis gas into substantially propanol or ° Is a microorganism, possessing the required nucleic acid sequence information to express the enzymes for the biosynthesis of C3-oxygenates, modified by conferring it with the required nucleic acid sequence information to express the enzymes of the Wood-Ljungdahl pathway (reduced Acetyl-CoA pathway), or ° Is a microorganism, possessing the required nucleic acid sequence information to express the enzymes of the Wood-Ljungdahl pathway (reduced Acetyl-CoA pathway), modified by conferring it with the required nucleic acid sequence information to express the enzymes for the biosynthesis of C3-oxygenates. o Dehydrating said above stream in a reactor at conditions effective to dehydrate at least a portion of the propanol to make propylene. |
