PROCESS FOR UPGRADING CRACKING CATALYTIC GASOLINE

The invention relates to a process for upgrading cracking catalytic gasoline. According to the installation, the process consists in the catalytic treatment, in the presence of hydrogen, of cracking catalytic gasoline as such or mixed with other light petroleum fractions in two reaction vessels with fixed catalyst beds, connected in series or in a single monolayer or double layer catalytic reactor wherein in two catalysts are placed separately or mixed, at a temperature in the range of 1...60 bars, for 2...10 h at a rate of volume flow of 0.5 : 10 h-1 in a molar ratio hydrogen / raw material of 1...12: 1. Inventia se refera la un procedeu de innobilare a benzinelor de cracare catalitica. Procedeul conform inventiei consta din tratarea catalitica, in prezenta hidrogenului, a benzinelor de cracare catalitica ca atare sau in amestec cu alte fractiuni petroliere usoare, in doua reactoare cu paturi fixe de catalizatori, conectate in serie sau intr-un reactor monostrat sau cu dublu strat catalitic, in care cei doi catalizatori sunt dispusi separat sau in amestec, la o temperatura de 300...500°C, o presiune de 1...60 bari, timp de 2..10 h, la o viteza volumara de 0,5 : 10 h-1 intr-un raport molar hidrogen : materie prima de 1...12 : 1.
