Résumé
Madagascar, the world's fourth largest island, is rich in biodiversity and mineral resources. There are huge deposits of hydrocarbons underground. Madagascar, for example, has a mining area called 3104 from Tsimiroro in the Morondava Basin, with an estimated 1.7 billion barrels of heavy oil reserves. Petroleum is both an energy source and a raw material. Therefore, the purpose of this study is to convert this heavy oil into different cuts. To this end, the methodology consisted of construction of a cracking plant, subsequent distillation of catalytic cracking products, and physicochemical analysis of heavy oil, cracking products and distillates. The results showed that the crude oil contained 46.58% aromatics with a viscosity and density of 2847.76 cSt and 0.98 respectively. Catalytic cracking produced 3.0% coke and 6.8% non-condensable gases, but the yield of combustible cracked oil reached 90%. The distillation of the cracked liquid produced light, medium and heavy fractions with a yield of respectively 14%, 78 % and 8 %. These results have shown the effectiveness of the process adopted, nevertheless, some improvements are being considered to optimize the quality of the fuel obtained. Of course, the use of eco-friendly alternatives is required to protect the environment, but for Madagascar, the development of this black resource, combined with measures to reduce environmental impact, is an important part of today's society, energy and It will be a way to overcome economic problems.
