Separation of branched hexane isomers using zeolite BEA for the octane improvement of gasoline pool.
| Resumo: | Along the last decades, the refining industry has attempted to enhance the octane quality of the gasoline (RON) fulfilling the environmental standards. The phase-out of the MTBE in several parts of the U.S. stresses the need for alternative solutions that can improve the RON without additives. The Total Isomerization Process (TIP) developed by Universal Oil Products is used to boost the RON of the light naphtha. It consist of a hydroisomerization reactor (Hysomer) and an adsorption unit (IsoSiv). The first unit convert low RON n-paraffins into high RON branched ones by an incomplete catalytic reaction while the second one remove the remaining n-paraffins from the output of the catalytic reactor recycling their back to the Hysomer in order to increase the conversion rate. The aim of this work consists in optimizing the existing TIP incorporating a second adsorption unit packed with a proper adsorbent, with the goal of removing the low RON monobranched C6 |
