СПОСОБ ДЕСУЛЬФУРИЗАЦИИ КАТАЛИТИЧЕСКИ КРЕКИРОВАННОЙ БЕНЗИНОЛИГРОИНОВОЙ ФРАКЦИИ (ВАРИАНТЫ)

Номер: RU2282659C2

FIELD: petroleum processing. SUBSTANCE: catalytically cracked gasoline-ligroin fraction is processed in first reaction-distillation column wherein diolefins and mercaptans react in presence of group VIII metal catalyst and hydrogen to form sulfur-containing products and heavier bottom gasoline-ligroin fraction. Bottom fraction and hydrogen are routed to second reaction-distillation column wherein sulfur-containing compounds contact with hydrogen in presence of hydrodesulfurization catalyst in rectification section. Second bottom fraction and hydrogen are routed to third reaction-distillation column wherein sulfides contact with hydrodesulfurization catalyst in presence of hydrogen to convert a part of sulfides into hydrogen sulfide. The thus obtained gasoline-ligroin fraction id fractioned to remove hydrogen sulfide, which is withdrawn as main distillate, while heavy gasoline-ligroin fraction is recovered as bottom fraction.

Once the catalyst has passed through the reaction zone, it is then passed to a regeneration zone for regeneration. The process eliminates the need of passing the hydrocarbon feed through a sulfur sorber prior to entry into the reaction zone, as the spent catalyst which is leaving the reaction zone for regeneration acts as a sulfur sorber and removes the sulfur from the feed entering the reaction zone.

The UZM-8 and UZM-8HS are related in that the UZM-8HS are derived from the UZM-8 zeolite by treating the UZM-8 with a fluoro-silicate salt, an acid, etc. The UZM-8 and -8HS have unique x-ray diffraction patterns. These zeolites can be used in alkylation of aromatics, transalkylation of aromatics, isomerization of aromatics and alkylation of isoparaffins.

A hydrogen desulfurizer (11) includes a tank (17) designed for downflow of hydrocarbon feedstock containing a plurality of layers (41-44) of catalyst interspersed with layers (46-49) of adsorbent. The layers may all comprise baskets, the adsorbent comprising pellets, such as zinc oxide pellets; the catalysts may be wash-coated on catalyst support such as monolith or foams, or may be wash-coated on netted wire mesh instead of being contained in a basket. The catalyst is heated to between about 442° F. (250° C.) and about 932° F. (500° C.). A mini-CPO (36) supplies hydrogen to the desulfurizer (11). Heaters (53, 55), which may either be electric or circulating heated fluid may also be used.

Methods and catalysts are provided for performing dewaxing of diesel boiling range fractions, such as trim dewaxing, that allow for production of diesel boiling range fuels with improved cold flow properties at desirable yields. In some aspects, the methods can include use of dewaxing catalysts based on an MEL framework structure (ZSM-11) to provide improved dewaxing activity. This can provide sufficient dewaxing activity to achieve a desired level of improvement in cold flow properties at the lower hydrotreating temperatures that are generally desired near the start of operation of a hydrotreating reactor. In other aspects, the methods can include use of MEL dewaxing catalysts with reduced ratios of molecular sieve to binder so that trim dewaxing can be provided while maintaining a desirable yield under end-of-run hydrotreating conditions. 119-.
