摘要： For the removal of trace quantities of iodine-containing contaminants from corrosive liquid feed streams, an adsorbent with distinct advantages over prior-art materials is provided. The treatment method involves the use of a metal phthalocyanine compound where the metal selected from the group consisting of silver, mercury, copper, lead, thallium, palladium, or mixtures thereof. Such metals are known to be reactive with the iodine-containing contaminants in the feed stream. Furthermore, the metal phthalocyanine is deposited on a carrier material selected from the group consisting of an activated carbon, a phenolic polymer, and an inorganic refractory metal oxide. Such adsorbent materials have proven substantially insoluble even in corrosive liquid feed streams associated with the invention. Reactivation and regeneration techniques, which are generally incompatible with prior-art adsorbent materials, are also disclosed.

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： An integrated process to produce diisopropyl ether from propane has been developed. In a first reaction zone the propane in a feedstock, after any hydrocarbons containing four or more carbon atoms are removed from the feedstock via fractionation, is dehydrogenated in the presence of a dehydrogenation catalyst to form propylene. After removing hydrogen, the propane and propylene mixture generated in the first reaction zone is separated into a propane enriched stream and a propylene enriched stream where the propylene enriched stream contains at least 65 mass % propylene. The propane enriched stream is recycled to the feedstock fractionation unit, and the propylene of the propylene enriched stream is reacted with water in a second reaction zone in the presence of an acidic catalyst to form isopropyl alcohol which is concurrently reacted with propylene to produce diisopropyl ether. A portion of the second reaction zone effluent is recycled to the second reaction zone, and the remainder may be collected or further separated to provide a high purity diisopropyl ether product. A variant to produce high purity propylene as well as diisopropyl ether is also discussed.

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： The present invention relates to a process and apparatus for the production of light olefins comprising olefins having from 2 to 3 carbon atoms per molecule from a feedstock containing heavier olefins. An intermediate cut from a fractionation column is used as olefinic feed to an olefin cracking process preferably after undergoing selective hydrogenation of diolefins. In one embodiment, a liquid side draw from a fractionation column is selectively hydrogenated and then returned to the fractionation column from which a vapor side draw containing olefins is cracked in the olefin cracking reactor.
