Abstract
A process can include making a bio-diesel, a bio-naphtha, and optionally bio-propane from a complex mixture of natural occurring fats & oils. The complex mixture can be subjected to a refining treatment for removing a major part of non-triglyceride and non-fatty acid components to obtain refined oils. The refined oils can be subjected to a fractionation step to obtain a substantially unsaturated liquid triglyceride part (phase L), and a substantially saturated solid triglyceride part (phase S). The phase L can transformed into alkyl-esters as bio-diesel by a transesterification. The phase S can be transformed into substantially linear paraffin's as the bio-naphtha by an hydrodeoxygenation. Fatty acids can be obtained from the phase S and transformed into substantially linear paraffin's as the bio-naphtha by hydrodeoxygenation or decarboxylation. Fatty acids soaps can be obtained from the phase S that are transformed into substantially linear paraffin's as the bio-naphtha by decarboxylation.
