    • A process for maximizing p-xylene production includes producing a naphtha fraction and a light cycle oil fraction from a fluid catalytic cracking zone. These fractions are combined and hydrotreated. Fractionation of the hydrotreated product makes a hydrocracker feed that is sent to a hydrocracking zone to make a naphtha cut and a hydrocracker product. The hydrocracker product is recycled back to the fractionation zone, and the naphtha cut is dehydrogenated in a dehydrogenation zone to make aromatics. Reforming catalyst from a catalyst regenerator moves downward through the dehydrogenation zone. Straight run naphtha and raffinate from the aromatics unit are introduced to an additional series of reforming zones. The reforming catalyst moves in parallel through the first reforming zone and the dehydrogenation zones, then is combined for entry to the second and subsequent reforming zones prior to regeneration.
    • 最大化对二甲苯生产的方法包括从流化催化裂化区产生石脑油馏分和轻循环油馏分。 将这些级分合并加氢处理。 加氢处理产物的分级使得加氢裂化器进料被送入加氢裂化区以制备石脑油馏分和加氢裂化产物。 将加氢裂化产物再循环回分馏区,并在脱氢区中脱氢石脑油馏分以制备芳族化合物。 催化剂再生器重整催化剂向下移动通过脱氢区。 来自芳烃单元的直馏石脑油和萃余液被引入另外的一系列重整区。 重整催化剂通过第一重整区和脱氢区平行移动,然后在再生之前组合进入第二和随后的重整区。

    • A reforming process includes integrating catalytic cracking product naphtha dehydrogenation and naphtha from a hydrocracking zone and feeding them to a dehydrogenation zone. The dehydrogenation zone includes a first portion of reforming catalyst from a catalyst regenerator that moves downward through the dehydrogenation zone. A product stream from the dehydrogenation zone flows to an aromatics unit and is separated into an aromatic-rich extract and a raffinate. Straight run naphtha and the raffinate are introduced to a first reforming zone that includes a second portion of reforming catalyst. The reforming catalyst moves through the first reforming zone then is removed from the bottom of each of the first reforming zone and the dehydrogenation zone and is fed to a second reforming zone. An effluent from the first reforming zone is fed to a plurality of reforming zones. The reforming catalyst moves downward through the multiple refoiniing zones then to a regenerator.
    • 重整过程包括将加氢裂化区的催化裂化产物石脑油脱氢和石脑油整合并将其送入脱氢区。 脱氢区包括从催化剂再生器向下移动通过脱氢区的第一部分重整催化剂。 来自脱氢区的产物流流入芳烃单元并分离成富含芳烃的提取物和萃余液。 将直馏石脑油和提余液引入到包含第二部分重整催化剂的第一重整区。 重整催化剂移动通过第一重整区,然后从第一重整区和脱氢区的每一个的底部移除,并被送入第二重整区。 来自第一重整区的流出物被供给到多个重整区。 重整催化剂通过多个回油区向下移动到再生器。
