    Abstract: A process is described for fixed bed hydrodesulfurizing a nonasphaltic oil feed or feed blend for a zeolitic FCC riser cracking system in which cracking occurs at a space velocity sufficiently high to prevent formation of a catalyst bed. It is found that sulfur dioxide emissions from the zeolite catalyst regenerator associated with the riser are reduced to a lower extent than total sulfur removal from the feed oil. This indicates uneven sulfur removal in the hydrodesulfurization step whereby a smaller portion of the sulfur is removed from the heavy portion of the feed from which the coke is derived than from the lighter portion of the feed. The present invention shows an advantage in keeping hydrocracking at a specified low level during the hydrodesulfurization step. This is accomplished in part by introduction of the high boiling portion of the feed to the upstream end of the hydrodesulfurization reactor and the low boiling portion of the feed downstream in the hydrodesulfurization reactor. In this manner maximum sulfur removal from the high boiling portion of the feed is approached, while hydrocracking is maintained at the specified low level. The further discovery is demonstrated herein that the ratio of gasoline to total conversion during the subsequent riser cracking step is enhanced by maintaining hydrocracking at said specified low level.

    Abstract translation: 描述了用于沸石FCC提升管裂解系统的非沥青油进料或进料共混物的固定床加氢脱硫的方法，其中裂纹以足够高的空间速度发生以防止形成催化剂床。 发现与提升管相关联的沸石催化剂再生器的二氧化硫排放量比从进料油中除去总硫的程度更低。 这表示在加氢脱硫步骤中不均匀的硫去除，其中较少部分的硫从可得到焦炭的进料的重部分除去，而不是从进料的较轻部分除去。 本发明显示出在加氢脱硫步骤期间将加氢裂化保持在特定低水平的优点。 部分通过在加氢脱硫反应器中将进料的高沸点部分引入加氢脱硫反应器的上游端和下游的进料的低沸点部分来实现。 以这种方式，最大程度地接近来自进料的高沸点部分的硫，同时加氢裂化保持在指定的低水平。 在本文中证明了进一步的发现，在随后的提升管裂解步骤期间汽油与总转化率的比例通过将加氢裂化维持在所述指定的低水平来增强。

    Abstract: A PROCESS FOR THE SELECTIVE HYDROGENATION OF DIOLEFINS OVER MONOOLEFINS IN AN AROMATIC DISTILLATE STREAM IN THE PRESENCE OF A NOBLE METAL CATALYST AT A TEMPERATURE BELOW ABOUT 350 TO 400*F. AT WHICH TEMPERATURE SAID AROMATIC DISTILLATE IS AT LEAST PARTIALLY IN THE LIQUID PHASE, IN THE PRESENCE OF A DILUENT HYDROCARBON HAVING A BOILING RANGE ABOVE SAID AROMATIC DISTILLATE WHICH INCREASES THE PROPORTION OF SAID AROMATIC DISTILLATE IN THE LIQUID PHASE AND THEREBY BOTH INHIBITS SOLID POLYMER FORMATION IN SAID PROCESS AND PROVIDES IMPROVED TEMPERATURE CONTROL.

    Abstract: A multiple stage hydrodesulfurization process is described for the catalytic hydrodesulfurization and hydrodemetallization of a residual petroleum oil boiling above the gasoline range followed by a zeolite riser cracking process. The product of the hydrodesulfurization section comprises essentially material boiling above the gasoline range and comprises little material boiling below the initial boiling point of the residual oil feed. The hydrodesulfurization-demetallization section comprises an initial stage involving relatively high hydrogen pressure in the presence of a catalyst comprising a relatively low proportion of catalytically active hydrogenation metals. The process employs a final hydrodesulfurization stage in series having a relatively lower hydrogen pressure and a catalyst comprising a relatively higher proportion of hydrogenation metals. The stream entering the final hydrodesulfurization stage contains an amount up to 10, 20 or even 25 weight percent of the asphaltene content of the charge to the first stage while the effluent from the final stage is essentially free of asphaltenes. The metals content of the final stage effluent is so low that said effluent can be charged without blending with a distillate oil to a fluidized zeolite riser cracking unit (FCC) to produce gasoline and fuel oil. The zeolite catalyst make-up requirement due to metals accumulation on the zeolite catalyst is no greater than zeolite make-up requirement when a distillate gas oil comprises the entire feed to the reactor. The sulfur content of the final stage effluent is so low that the sulfur dioxide content in the zeolite regenerator flue gas is able to meet commercial requirements and so that the fuel oil range product of the FCC operation is sufficiently low that the FCC fuel oil product also meets commercial fuel oil sulfur specifications without requiring further hydrodesulfurization, whereby all hydrodesulfurization can precede the FCC step and no hydrodesulfurization is required after the FCC step. Of course, further desulfurization can follow the FCC step, if such is desired for a specialized requirement.

    Abstract: THE HYDRODESULFURIZATION OF A HYDROCARBON OIL WITH A CATALYST COMPRISING A SUPPORTED GROUP VI AND GROUP VIII METAL IS IMPROVED BY SODIUM PROMOTION OF THE CATALYST. THE IMPROVED EFFECT IS SUPRISING BECAUSE OVER AN EXTENDED INITIAL STAGE OF THE PROCESS THE SODIUM ACTS AS A CATALYST POISON AND DEPRESSES CATALYST ACTIVITY. HOWEVER, AFTER A PERIOD OF AGING THE HYDRODESULFURIZATION ACITIVTY OF THE SODIUM-PROMOTED CATALYST EMERGES SUPERIOR TO THAT OF THE NON-PROMOTED CATALYST. THE SUPERIOR ACTIVITY OF THE AGED SODIUM-PROMOTED CATALYST IS INEXPLICABLE IN VIEW OF THE FACT THAT THE CARBON, SULFUR AND METALS LAYDOWN ON THE AGED SODIUM-PROMOTED CATALYST IS ABOUT AS HIGH AS ON THE AGED NON-SODIUM-PROMOTED CATALYST.
