METHOD OF TREATING GASOLINES RESULTING FROM SECONDARY PROCESSES Russian patent published in 1995 - IPC

Abstract RU 2043390 C1

FIELD: petrochemistry. SUBSTANCE: gasolines resulting from secondary processes are subjected to hydraulic treatment in two stages. The first stage catalyst comprises (wt): 0.5-0.65 platinum; 0.5-2.5 fluorine; and alumina, the balance. The second stage catalyst comprises (wt): 0.3-1.2 platinum or a mixture of platinum with promoter; 50.0-75.0 high-silica ZSM type zeolite in Na-form; and alumina, the balance. The catalysts ratio is (0.3-2.5): 1. The promoter is rhenium, iridium, rhodite tungsten or molybdenum. The platinum to promoter weight ratio is (0.5-12):1. EFFECT: more efficient treatment method. 3 cl, 1 tbl
