| Popis: | Residue conversion processes are becoming increasingly important in the world today, because of several market and economic factors. The residues contain a large mass fraction of heavy and polar compounds known as asphaltenes, which can cause major problems in the conversion processes. Heavy feedstocks with high asphaltene content can become an economic opportunity if they can be converted to lighter products. In this perspective, Eni has developed a process called EST (Eni Slurry Technology) to convert very heavy feedstocks into high quality transportation fuels. In the course of the EST process, the asphaltene molecules are converted to smaller fractions, enhanced to fuels; the unconverted fraction is recycled in the reactor and treated again and again. The technology is based on a very active, dispersed, nonaging slurry catalyst, which prevents coke formation and promotes upgrading reactions (sulfur, nitrogen, and metal removal and Conradson carbon residue (CCR) reduction). Knowledge of the asphaltene ... |
