Abstract

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.

Изобретение относится к нефтепереработке, конкретно к способам каталитического риформинга бензиновых фракций на полиметаллических катализаторах риформинга. Предлагается способ проведения каталитического риформинга бензиновых фракций на платино-рениевом катализаторе с очисткой циркулирующего водородсодержащего газа от сероводорода на регенерируемом адсорбенте путем введения предварительной стадии циркуляции водородсодержащего газа через пустые реакторы риформинга и слой регенерируемого адсорбента. Стадию осуществляют до загрузки катализатора риформинга при температуре в реакторах в интервале 350-520oC и продолжительности обработки не менее 1 суток. В качестве регенерируемого адсорбента предпочтительно применяют алюмоцинковый контакт со структурой шпинели. Предварительная стадия циркуляции водородсодержашего газа до загрузки катализатора риформинга через пустые реакторы и слой регенерируемого адсорбента на 0,5-2,0 % повышает выход ароматических углеводородов при жестких условиях проведения процесса.The invention relates to oil refining, specifically to methods for catalytic reforming of gasoline fractions on polymetallic reforming catalysts. A method is proposed for carrying out catalytic reforming of gasoline fractions on a platinum-rhenium catalyst with purification of the circulating hydrogen-containing gas from hydrogen sulfide on the regenerated adsorbent by introducing a preliminary stage of the circulation of the hydrogen-containing gas through the empty reforming reactors and the regenerated adsorbent layer. The stage is carried out before loading the reforming catalyst at a temperature in the reactor in the range of 350-520 o C and a processing time of at least 1 day. As a regenerated adsorbent, an aluminum-zinc contact with a spinel structure is preferably used. The preliminary stage of the circulation of the hydrogen-containing gas before loading the reforming catalyst through empty reactors and the regenerated adsorbent bed increases the yield of aromatic hydrocarbons by 0.5-2.0% under severe process conditions.
