Zusammenfassung: | Process for the production of hydrocarbon blends with a high octane number by the hydrogenation of hydrocarbon blends, containing branched C8, C12 and C16 olefinic cuts, characterized by sending said blends, as such or fraction ated into two streams, one substantially containing the branched C8 olefinic cut, the other substantially containing the branched C12 and C16 olef inic cuts, to a single hydrogenation zone or to two hydrogenation zones in parallel, respectively, only the stream substantially containing saturated C8 hydrocarbons, obtained by the fractionation of the stream produced by the single hydrogenation zone or obtained by the hydrogenation zone fed by the fractionated stream substantially containing the branched C8 olefinic cut, being at least partly recycled to the single hydrogenation zone or to the hydrogenation zone fed by the fractionated stream substantially containing the branched C8 olefinic cut, and the hydrocarbon blend with a high octane number, obtained by the fractionation of the stream produced from the single hydrogenation zone or obtained from the hydrogenation zone, being fed by the fractionated stream substantially containing the branched C12 and C16 olefinic cuts.
Proceso para la produccion de mezclas de hidrocarburo con un numero alto de octano a traves de la hidrogenacion de mezclas de hidrocarburo, que contienen cortes olefinicos de C8, C12 y C16 ramificados, caracterizado por enviar las mezclas, como tales o fraccionadas en dos corrientes, una que contiene sustancialmente el corte olefinico de C8 ramificado, la otra que contiene sustancialmente los cortes olefinicos de C12 y C16 ramificados, a una zona unica de hidrogenacion o a dos zonas de hidrogenacion en paralelo, respectivamente, solo la corriente que sustancialmente contiene los hidrocarburos de C8 saturados, obtenidos por el fraccionamiento de la corriente producida por la zona unica de hidrogenacion u obtenida por la zona de hidrogenacion alimentada por la corriente fraccionada que sustancialmente contiene el corte olefinico de C8 ramificado, siendo al menos parcialmente reciclada hacia la zona unica de hidrogenacion o hacia la zona de hidrogenacion alimentada por la corriente fraccionada que sustancialmente contiene el corte olefinico de C8 ramificado, y la mezcla de hidrocarburo con un numero de octano alto, obtenida por el fraccionamiento de la corriente producida desde la zona unica de hidrogenacion u obtenida desde la zona de hidrogenacion que es alimentada |
