STEAMCRACKING BIO-NAPHTHA PRODUCED FROM COMPLEX MIXTURES OF NATURAL OCCURRING FATS AND OILS

摘要

A process for making a bio-naphtha and optionally bio-propane from a complex mixture of natural occurring fats & oils, wherein
said complex mixture is subjected to a refining treatment for removing the major part of non-triglyceride and non-fatty acid components, thereby obtaining refined fats & oils;said refined fats & oils are transformed into linear or substantially linear paraffin's as the bio-naphtha by an hydrodeoxygenationor from said refined fats & oils are obtained fatty acids that are transformed into linear or substantially linear paraffin's as the bio-naphtha by hydrodeoxygenation or decarboxylation of the free fatty acidsor from said refined fats & oils are obtained fatty acids soaps that are transformed into linear or substantially linear paraffin's as the bio-naphtha by decarboxylation of the soaps.
