摘要： A hydrocarbon conversion process for producing C.sub.8 hydrocarbons suitable for use as motor fuel blending components from normal butane or a mixture of isobutane and normal butane. A butane feed stream is fractionated to produce a normal butane stream which is passed through a butane isomerization zone. The effluent of the isomerization zone is admixed with isobutane and passed into a butane dehydrogenation zone. The C.sub.4 effluent of the dehydrogenation zone is passed into an HF alkylation zone in which C.sub.8 hydrocarbons are produced. The alkylation zone effluent stream is passed into the feed stream fractionator. Preferably, an isobutane stream is withdrawn from the feed stream fractionator and divided into a portion which is passed into the dehydrogenation zone and a portion passed into the alkylation zone based on a measurement of the isobutane inventory of the process.

摘要： A process for the separation of isobutane from an alkylation reaction zone hydrocarbon effluent stream comprising isobutane, n-butane, propane and alkylate is disclosed. The hydrocarbon effluent stream is charged to an isostripper column. An isobutane vapor stream from the column is condensed in indirect heat exchange with the lower liquid stream from said column comprising n-butane. The lower liquid stream is flashed in indirect heat exchange with said vapor stream at conditions to provide a vapor phase, said vapor phase being compressed and recycled to said column at a temperature to promote vapor formation therein.

摘要： The average propylene cycle selectivity of an oxygenate to propylene (OTP) process using a dual-function oxygenate conversion catalyst is substantially enhanced by the use of a combination of: 1) moving bed reactor technology in the hydrocarbon synthesis portion of the OTP flow scheme in lieu of the fixed bed technology of the prior art; 2) a hydrothermally stabilized and dual-functional catalyst system comprising a molecular sieve having dual-function capability dispersed in a phosphorus-modified alumina matrix containing labile phosphorus and/or aluminum anions; and 3) a catalyst on-stream cycle time of 400 hours or less. These provisions stabilize the catalyst against hydrothermal deactivation and hold the build-up of coke deposits on the catalyst to a level which does not substantially degrade dual-function catalyst activity, oxygenate conversion and propylene selectivity, thereby enabling maintenance of average propylene cycle yield near or at essentially start-of-cycle levels.

摘要： For the removal of trace quantities of iodine-containing contaminants from corrosive liquid feed streams (e.g. commercial acetic acid), an adsorbent with distinct advantages over prior-art materials is provided. The overall treatment method involves the use of a suitable zeolite having a silica to alumina molar ratio from about 5 to less than 15 that has been cation-exchanged with an iodine-reactive metal. This inorganic adsorbent may be used in unbound form, or it can be bound with a substantially insoluble porous inorganic refractory metal oxide binder. Reactivation and regeneration techniques, which are generally incompatible with prior-art adsorbent materials, are also disclosed. In general, it is advantageous to pretreat the feed streams to remove the most easily separable contaminants (e.g. iodine, hydrogen iodide, and metal cations) and thereby reduce the iodine compound loading and detrimental effects of metals on the adsorbent. Thus, the expensive iodine reactive metal (e.g. silver) used in the adsorbent preparation is judiciously used for the removal of trace quantities of iodine-containing species (e.g. alkyl iodides) that are not readily separable by other means.

摘要翻译： 为了从腐蚀性液体进料流（例如商业乙酸）中除去痕量的含碘污染物，提供了与现有技术材料相比具有明显优点的吸附剂。 总体处理方法包括使用与碘反应性金属进行阳离子交换的具有约5至小于15的二氧化硅与氧化铝摩尔比的合适的沸石。 该无机吸附剂可以以未结合的形式使用，也可以与基本上不溶的多孔无机难熔金属氧化物粘合剂结合。 还公开了通常与现有技术吸附材料不相容的再活化和再生技术。 通常，有利的是预处理进料流以除去最容易分离的污染物（例如碘，碘化氢和金属阳离子），从而降低碘化合物的负载量和金属对吸附剂的不利影响。 因此，在吸附剂制备中使用的昂贵的碘反应性金属（例如银）被明智地用于除去不易通过其它方法分离的痕量的含碘物质（例如烷基碘化物）。

摘要： A process and apparatus for contacting reactants with a particulate catalyst while indirectly contacting the reactants with a heat exchange medium performs heat exchange in a first reaction zone and moves catalyst, at least intermittently, through the second reaction zone while the process is operating. The first reaction zone is preferably a fixed bed reaction zone. The use of first reaction zone as a fixed bed reaction zone simplifies the process arrangement by not requiring means for catalyst movement in a reaction zone that performs simultaneous heat exchange. Long periods of operation are possible since the first reaction zone will typically experience a slow rate of catalyst deactivation and need infrequent regeneration. The first reaction zone may also be designed for catalyst movement, but independently controlled from the first reaction zone to facilitate the movement of catalyst therethrough.

摘要： A process and apparatus cools a heat exchange type reaction zone by passing the incoming reactants through heat exchange channels in heat exchange relationship with the reaction zone. The invention simplifies the operation and construction of the heat exchanging type reaction zone by directly communicating reaction channels that contain the reaction with the heating channels that heat reactant across an open manifold located at the end of the channels. Additional reactants, cooling fluids, or other diluents may enter the process directly through the manifold space to permit further temperature control of the reaction zone. The invention promotes better heat transfer efficiency than tube and shell heat transfer arrangements that have been used for similar purposes. The narrow channels are preferably defined by corrugated plates. The reaction channels will contain a catalyst for the promotion of the primary reaction.
