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： 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.

摘要： The present invention provides an integrated process for the production of propylene oxide from an alternate feedstream such as synthesis gas. In the process, propylene oxide is produced from a feedstream comprising hydrogen and a carbon oxide. A portion of the feedstream is passed to an oxygenate production zone to produce an oxygenate stream comprising methanol and dimethyl ether, and the oxygenate stream is passed to an olefin production zone containing a metal aluminophosphate catalyst to produce a propylene stream. The propylene stream is epoxidized with hydrogen peroxide which has been produced from hydrogen separated from a portion of the feedstream. The spent water stream produced by the epoxidation reaction is treated to remove heavy components and returned to the hydrogen peroxide production zone. The return of the unreacted propylene from the epoxidation reaction zone for its subsequent recovery and recycle permits a less complicated, lower energy propylene separation. The recycling of spent water from the epoxidation reaction zone and the removal of heavy compounds eliminates a low value water stream and the recovery of heavy hydrocarbons therefrom produces a valuable secondary product.

摘要： A multistep hydrocarbon conversion process for the production of ethers including methyl tertiary butyl ether (MTBE) from light paraffins and alcohols is disclosed. A mixture of C.sub.4 isoparaffins, normal paraffins, an etherification recycle and butane isomerization effluent enter a deisobutanizer column. Normal paraffins withdrawn from the fractionator are isomerized and returned to the fractionator, and isoparaffins are withdrawn from the fractionator and dehydrogenated. The resulting olefins enter an etherification zone for reaction of isobutene with a C.sub.2 -C.sub.5 alcohol. Unreacted paraffins and olefins comprise a portion of the etherification effluent entering the deisobutanizer. After separation for recovery of the ether product, unreacted paraffins and olefins are passed through a dehydrogenation zone for saturation of the olefins and then returned to the deisobutanizer column. Normal butanes are withdrawn as a sidecut from the deisobutanizer. The sidecut passes to an isomerization zone and a mixture of isobutane and normal butane is recycled to the deisobutanizer. In a highly preferred embodiment, spent catalyst from the isomerization zone fulfills the catalyst requirement of the dehydrogenation zone.

摘要： A hydrocarbon conversion process is disclosed which may be used to produce high purity isobutylene and/or tertiary butyl alcohol and methyl tertiary butyl ether. A mixed C.sub.4 feed stream is divided into two portions with a first portion being passed through a hydration zone to produce the tertiary butyl alcohol. The remaining hydrocarbons withdrawn from the hydration zone and the second portion of the feed stream are changed to an etherification zone. The unconverted hydrocarbons exiting the etherification zone may be subjected to isomerization and/or dehydrogenation to produce additional isobutylene. The high purity isobutylene is obtained by dehydrating the tertiary butyl alcohol.
