    摘要： A process for production of alcohol or ether by hydration of olefinic feedstock containing at least one lower alkene by contacting the olefinic feedstock and water in a hydration zone with porous solid metal oxide acidic olefin hydration catalyst under olefins hydration conditions. The process is characterized by the step of pretreating porous solid catalyst, such as acid zeolite, prior to contacting with the olefinic feedstock with a wetting agent containing at least one polar aliphatic oxygenated hydrocarbon to substantially wet said solid catalyst and sorb said wetting agent into pores of said solid catalyst. After initiating hydration reaction by feeding the olefinic feedstock and water, increased catalytic activity is obtained. The process is particularly useful for making isopropanol and DIPE from propene and water.

    摘要： Light olefins are catalytically converted to ethers, e.g., propylene is converted to diisopropyl ether, in a dual stage process in which product ether is recycled to a first stage reaction zone to significantly reduce the operating temperature of the olefin hydration/etherification reactions taking place in that zone. Alcohol produced in the first stage reaction zone undergoes conversion in the second stage reaction zone, e.g., by etherification with light olefin or by catalytic distillation, to provide additional product ether. The process contemplates the use of zeolites as olefin hydration/etherification catalysts.

    摘要： A single path process for alkylating a hydrocarbon feedstock containing an olefin and an isoparaffin is disclosed. The process includes dispersing an acid-based liquid alkylation catalyst into a reaction zone for contact with a continuous hydrocarbon phase. The process further includes separating the hydrocarbon phase from the acid catalyst upon completion of the alkylation reaction and providing a continuous on-line regeneration of the entire volume of catalyst once it has been separated from the hydrocarbon phase.
