Abstract : As acids are intermediates during the catalytic conversion of triglycerides to hydrocarbons, the purpose of this research was to investigate octanoic acid conversion to hydrocarbons. The shortage of oil resources has led to the development of new technologies that can more fully exploit renewable energies such as fats (rape or sunflower oils) and their derivatives. The general aim of this study is to produce chemical base products with high added value in lubricant and detergent sectors. To increase the knowledge of vegetable oil catalytic cracking, a laboratory pilot was conceived in Nancy. To describe the running conditions of the fixed bed reactor, the physical quantities (mass of oil per mass of catalyst per hour, time of contact,...) were defined. Liquid and gaseous products were analyzed by GC/MS and gas chromatography and CO-CO2 by infrared spectrometry. The conversion of octanoic acid and yields of products (ketones, hexene, nonene,...) showed that there is a close link between the type of catalyst and product distribution; the best conversion of octanoic acid was obtained with activated alumina. This emergent oils and fats chemistry field could lead to new processes and new products (lubricants, surfactants) coming from vegetable oils and therefore biodegradable. (Résumé d'auteur)
