摘要： An improved catalytic reforming process. The process is operated at high severity in order to obtain a reformate product having an enhanced octane rating. Higher octane reformate is required to compensate for the reduction or total elimination of lead-based additives used in motor gasoline for increasing octane rating, since reformate is a primary component of motor gasoline. High severity operation results in the formation of quantities of polycyclic aromatic compounds whose presence is highly undesirable. These compounds are removed from the vaporous products of the catalytic reforming process by adsorption on an appropriate material. It was totally unexpected to find that these very high molecular weight compounds are present in vapor streams comprised of hydrogen and light normally-gaseous hydrocarbons such as methane, ethane, and propane.
摘要翻译：改进的催化重整过程。该方法以高度苛刻度操作，以获得具有增强的辛烷值的重整产物。需要更高辛烷值的重整油来补偿汽油中用于提高辛烷值的铅基添加剂的减少或完全消除，因为重整油是汽油的主要成分。高度严格的操作导致形成多环芳族化合物的量，其存在是非常不希望的。这些化合物通过在合适的材料上吸附从催化重整过程的蒸气产物中除去。完全意外的是发现这些非常高分子量的化合物存在于由氢气和轻质正常气体烃如甲烷，乙烷和丙烷组成的蒸汽流中。

摘要： A multiple-stage catalytic conversion system in which a hydrocarbonaceous charge stock and hydrogen flow serially through a plurality of catalytic reaction zones in each of which the catalyst particles are movable via gravity flow. Dissimilar catalyst particles are utilized in the reactor systems which share a common regenerating tower through which the catalyst particles are downwardly movable via gravity flow and in which the catalyst particles are regenerated in segregated fashion. Dissimilarity of the catalyst particles stems from a difference in activity, stability and selectivity characteristics. In turn, this difference may be attributed either to physical, or chemical distinctions between the two composites, or both.
摘要翻译：一种多级催化转化系统，其中烃质电荷原料和氢气连续地流过多个催化反应区，其中催化剂颗粒可通过重力流动移动。不同的催化剂颗粒用于共用共用再生塔的反应器系统中，催化剂颗粒可以通过重力流向下运动，催化剂颗粒以分离的方式再生。催化剂颗粒的不相似性源于活性，稳定性和选择性特征的差异。反过来，这种差异可能归因于两种复合材料之间的物理或化学差异，或两者兼有。

摘要： The present invention is directed to a device for interactive psycho/social evaluation and treatment of individuals, and to a method of using the device in the evaluation and treatment of individuals. The client is asked to distribute, under specific headings, 31 adjective words that describe their behavior. This distribution, along with some internal test manipulation not only pictures their behavior but their defense mechanisms, as well. As the client describes the reasons for the distribution of adjective words, important psycho/social historical information is also obtained.
摘要翻译：本发明涉及一种用于个体的交互式心理/社会评估和治疗的装置，以及在个人的评估和治疗中使用该装置的方法。要求客户在特定标题下分发31个描述其行为的形容词。这种分配，以及一些内部测试操纵，不仅描绘了他们的行为，而且是他们的防御机制。由于客户描述了形容词分发的原因，也获得了重要的心理/社会历史信息。

摘要： An improved method for processing the effluent of a hydrocarbon conversion zone. The invention is particularly useful in a catalytic reforming reaction, wherein practice of the invention results in an increased recovery of butane and propane. The effluent is separated into vapor and liquid components, which are then recontacted at a higher pressure. Several recontacting steps may be employed. Liquid product is then subjected to fractionation. Overhead vapor from the fractionation zone is recycled back to a recontacting step in order to recover a portion of the hydrocarbons contained therein, instead of routing the vapor to the plant fuel gas system.
