摘要： An FCC feed injection arrangement injects feed transversely from the sides of a restricted opening into a stream of FCC catalyst to provide good feed and catalyst contacting in an arrangement that simplifies external pipe configurations and maintenance of the feed injection system. The invention forms a venturi or restricted opening by forming a generally square opening between two parallel extended chords on opposite sides of the riser. A venturi area may be built out of refractory lining or other abrasion resistant structures. The invention may use horizontally extended pipes that are tangentially positioned apart from each other across from the restricted opening to provide a simple construction for the feed injection arrangement. The pipes are easily inserted and withdrawn from the riser to permit easy maintenance of the nozzles in the highly erosive environment. Insertable pipe distributors for distributing feed may be arranged to provide good overall distribution while also providing cooling to the outer surface of the distribution conduit to prevent coking. The distribution conduit may also be arranged to provide mixing of oil and steam near the injection point of the nozzles.
摘要翻译： FCC进料喷射装置将进料横向从限制孔的侧面进入FCC催化剂流中，以提供良好的进料和催化剂接触，从而简化外部管道配置和维持进料系统。本发明通过在提升管的相对侧上的两个平行延伸的和弦之间形成大致正方形的开口形成文氏管或限制开口。文丘里区域可以由耐火衬里或其他耐磨结构构成。本发明可以使用横向延伸的管道，其相互间隔开限制开口彼此分开定位，以提供用于进料喷射装置的简单结构。这些管道很容易从提升管中插入和取出，以便在高侵蚀性环境中容易地维护喷嘴。用于分配进料的可插入管道分配器可以布置成提供良好的总体分布，同时还向分配管道的外表面提供冷却以防止焦化。分配导管还可以布置成在喷嘴的喷射点附近提供油和蒸汽的混合。

摘要： A method and apparatus for alkylating an alkylation substrate with an alkylating agent in the presence of solid catalyst particles in a transport reactor is disclosed. Solid catalyst particles in the transport reactor effluent recirculate to the inlet of the transport reactor through one or more conduits. The rate through each conduit is regulated by fluid-controlled valves that use the alkylation substrate as the regulating fluid. This method and apparatus help ensure uniform or symmetric flow of catalyst from the effluent of the transport reactor to the bottom of the transport reactor. This method and apparatus also help ensure uniform or symmetric flow of alkylation substrate to the bottom of the transport reactor with minimal bypassing by the alkylating agent around of the transport reactor. This invention finds use in the production of motor fuels by the alkylation of liquid hydrocarbons in the presence of solid catalyst particles.

摘要： An arrangement for the controlled production of an essentially linear array of hydrocarbon feed injection jets reduces required clearances and elevation while facilitating modification of the contacting locating a feed distributor containing a linear array of jets at a standpipe junction point to provide choke point for particle flow control. The flow properties of the extended particle layer are controlled by adjusting the density of the particles above the choke point created by the upper part of the standpipe inside diameter and the top of the distributor. Steam or another fluidization medium may be added to the particles directly above the distributor for this purpose. This invention can also modify the particle or feed injection characteristics by changing the projection of the distributor into the standpipe to adjust the flow area over the choke point and by the use of bottom slides or baffles to change the flow area size and configuration. Location of the distributor at a standpipe junction will also typically allow the placement of the distributor at a lower location in the process which eliminates the need to add vessel height for supplying pressure drop for the particle discharge point. The distributor arrangement also fits compactly into most common standpipe junctions. Thus, the arrangement of this invention solves the problem of inserting an extended array of feed injection points into a fluidized particle contacting process without providing a large amount of clearance or additional vessel height.
摘要翻译：用于控制生产基本上线性的烃类进料喷射喷嘴的装置减少了所需的间隙和高度，同时促进了在竖管连接点处定位含有线性阵列阵列的进料分配器的接触的修改，以提供用于颗粒流控制的阻塞点。扩展颗粒层的流动特性通过调节由竖管内部直径的上部和分配器的顶部产生的阻塞点之上的颗粒的密度来控制。为此目的，可以将蒸汽或另一种流化介质加入分布器正上方的颗粒。本发明还可以通过改变分配器到立管中的投影来调整颗粒或进料注入特性，以调节阻塞点上的流动面积，并且通过使用底部滑块或挡板来改变流动面积的大小和构型。分配器在立管接头处的位置通常还允许将分配器放置在该过程中的较低位置处，这消除了增加用于为颗粒排放点提供压降的容器高度的需要。分配器安排也紧凑地配合到大多数常见的立管接头中。因此，本发明的装置解决了将延伸的进料喷射点阵列插入到流化颗粒接触过程中而不提供大量间隙或另外的容器高度的问题。

摘要： An improved process for the catalytic dehydrogenation of paraffinic hydrocarbons is disclosed. Feed paraffinic hydrocarbons are dehydrogenated by means of contacting the dehydrogenatable hydrocarbon with a dehydrogenation catalyst in a first dehydrogenation zone wherein the endothermic dehydrogenation reaction reduces the temperature of the resulting hydrocarbon stream containing dehydrogenated hydrocarbon compounds. The resulting effluent from the first dehydrogenation zone is then contacted with a stream of gas comprising normally gaseous hydrocarbon compounds having a temperature greater than the hydrocarbon stream to increase the temperature of the hydrocarbon stream and then introducing the resulting heated stream into a second dehydrogenation zone to produce additional dehydrogenated hydrocarbon compounds.
