    摘要： The present invention comprises a process for removal of oxygenates from a paraffin-rich or olefin-rich paraffin stream which comprises passing a feed stream, comprising one or more C10 to C15 feed paraffins or C10 to C15 olefin-rich paraffin stream and one or more oxygenates through an adsorbent bed comprising one or more adsorbents selected from silica gel, activated alumina and sodium x zeolites to remove essentially all of said oxygenates; and recovering said paraffins. A second adsorbent bed may be employed to more thoroughly remove these oxygenates.

    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： 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.
