A process for making propylene by dehydration of propanol can include gasifying a carbonaceous solid or liquid feedstock, or reforming a gaseous carbonaceous feedstock into synthesis gas. The synthesis gas can be fermented or co-fermented by means of a microorganism into propanol. The microorganism can be a wild strain having the natural capability to ferment synthesis gas into propanol. The microorganism can be a microorganism possessing the required nucleic acid sequence information to express the enzymes for the biosynthesis of C3-oxygenates modified with the required nucleic acid sequence information to express the enzymes of the Wood-Ljungdahl pathway. The microorganism can be a microorganism possessing the required nucleic acid sequence information to express the enzymes of the Wood-Ljungdahl pathway, modified with the required nucleic acid sequence information to express the enzymes for the biosynthesis of C3-oxygenates. The stream can be fractionated, purified, and then dehydrated at conditions effective to make propylene. |
