METHOD FOR CATALYTIC REFORMING

摘要

FIELD: oil processing industry; methods for catalytic reforming of gasoline fractions on polymetallic reforming catalysts. SUBSTANCE: proposed method for catalytic reforming of gasoline fractions on platinum-rhenium catalyst comprises following features of inventive novelty: circulating hydrogen-containing gas is purified from hydrogen sulfide on regenerative adsorbent by introducing preliminary step of circulating hydrogen-containing gas through empty reforming reactors and through regenerative absorbent bed. This preliminary step is carried out prior to charging reforming catalyst into reactors having temperature within range 350-520 C, treatment duration being at least 24 h. It is preferable that aluminium-zinc contact having spinel-type structure be used as generatable adsorbent. Inventive preliminary step of circulating hydrogen-containing gas through empty reactors and regeneratable adsorbent bed prior to charging reforming catalyst increases by 0.5-2.0% yield of aromatic hydrocarbons under severe process conditions. EFFECT: increased oil reforming process efficiency.
